If you follow us regularly, a few weeks ago we reviewed the QIDI X-Max 3, a printer that we liked in several aspects but could be improved in others. On this basis, we were especially interested in how this new QIDI Tech model, the QIDI Q1 Pro, has improved those aspects to be polished that we detected during our review. Let’s get to it!!
As always before continuing with the article, remind you that you can join 3DWork on our Telegram channel full of 3D printing derangers, or on our social networks Instagram, YouTube, TikTok, TwitterandFacebook.
QIDI Q1 Pro
Like the models previously analysed by our QIDI Tech side, it is a fully enclosed printer, with CoreXY kinematics prepared for high speeds of up to a theoretical 600 mm/s through accelerations of 20000 mm/s2. In this case, the QIDI Q1 Pro has a print volume of 245x245x240 mm
Within the extrusion system QIDI has included a double filament detection system, and we can tell you that in our tests it has worked really well, which will allow us to detect blockages in the supply of filament and lack of it so that our prints never fail.
Like previous models, this QIDI Q1 Pro features robust, reliable and precise kinematics in the CoreXY format using axial linear guides for fast movements with low inertia to improve print quality.
It also has an “All-metal” structure that will provide stability and robustness to the whole. A new aspect in this model compared to the previous ones has been the implementation of an independent double Z-axis and a renewed leveling system that we will talk about in detail later.
We will also highlight the inclusion of an active heating system of the enclosure, something essential if we want to work on certain technical filaments. The system will allow us to maintain the printing area up to about 60ºC, which will improve adhesion problems between layers (“chapping”) and improve adhesion to the platform (“warping”).
Like the previous models, the machine works using Klipper, a version customized by QIDI and which we will talk about later, to get the maximum performance from the machine.
On the electronic side, which we will give you more details later, we have a 64b processor for the Klipper host part along with an EMMC of 32GB of storage so that we don’t have problems when it comes to managing our print history or timelapses. In the management of the printer we have TMC2240 drivers that, in addition to helping to improve the management of the motors and their kinematics, will do so by generating the minimum noise from the motors and optimizing current consumption, as well as significantly improving the generation of heat in the drivers.
Thanks to the use of Klipper and its freedom to expand and customize the system, we have two other functions that can be very useful… the inclusion of a 1080p camera with which we will be able to timelapse and/or remotely monitor our prints and another interesting improvement is that we will have a mobile application to be able to manage our printer from anywhere.

QIDI Q1 Pro Kit Contents
The QIDI Q1 Pro comes perfectly packaged and despite its contained print volume when closed and the enclosure format that QIDI usually uses, the package is a little bulky, although much more manageable than the QIDI X-Max 3, of course.
All components and accessories are perfectly protected andwe find everything you need for start-up, first tests and basic maintenance of the machine.
QIDI Q1 Pro Initial Installation
Once we have all the anchors removed it is time to install the filament spool holder, the bobbin and following the on-screen process load the filament into the printer’s extrusion system.
The process is very simple by following the instructions in the on-screen wizard.
Once we have loaded the filament, the next step of the wizard will perform a verification of the positioning of the bed and printhead and a cleaning of the nozzle. The Q1 Pro has a cleaning and purging system for the filament that we will tell you about later.
As a last step, it will carry out an Input Shaper test, vibration compensation, to improve the quality of our prints thanks to the accelerometer integrated in the print head. This process vibrates the printhead at different frequencies to detect the vibrations and get the sweet spot of our machine to reduce them.
We’ve got our Q1 Pro ready!! In any case, we attach a video of QIDI that you can find on their Youtube channel where you can see this whole process.
Q1 Pro Component & Mechanical Analysis
Kinematics
As we told you in the introduction of the Q1 Pro, it has a CoreXY kinematics, perfect for obtaining high-speed prints with precision and generating few vibrations… all mounted on a sturdy internal metal structure.
A novelty in this QIDI model is the use of a double independent motor in the dual Z system that supports the printing platform, separate drivers in the electronics, which will allow us to use an alignment functionality of this double Z.
This will allow us to always have everything correctly leveled, aligned and in an automated way thanks to the use of the leveling sensor.
Extrusion system, printing platform and enclosure heating system
We will start by reviewing the extrusion system which, we like, has been improved in several aspects over its sisters, which was one of the points that gave us problems in previous versions.
We can access the hotend in a very simple way without the need for tools to remove the front part.
Although it still mounts a proprietary system in this version they have modified the design by polishing aspects of previous versions, now the cooling system of the hotend does its job more optimally avoiding unnecessary jams.
Taking into account that it can reach 350º and a flow, depending on conditions, of up to about 35 mm3/s will allow us to print at high speeds and the use of technical materials such as PC, ABS/ASA, PET-CF, Nylon or CF. Although in our tests we have not reached the theoretical values, being on average between 10-15 mm3/s.
The extrusion motor is located in the print head, direct extrusion, and uses a gear system to supply filament to the hotend with a ratio of 9.5:1 that will provide good grip and speed to maintain the filament flow necessary for the assembly.
We also have a leveling sensor, an inductive probe which will facilitate the process of aligning Z axes, manual leveling assisted by the sensor of the printing platform as well as the meshing of the printing surface to compensate for unevenness.
Another novelty of this Q1 Pro is the use of a nozzle purging/cleaning system, the first impression and appearance gives the feeling of a flimsy and unreliable solution but we have to tell you that it has worked quite well and the problems of filament debris are reduced when starting, restarting a print or in filament changes.
The system consists of a lever that, when pressed by the movement of the head, adjusts a bowl for filament purging, a metal cylinder to separate the purge from the nozzle and a nozzle cleaning area. Once the cleaning movements have been carried out and when the lever is no longer pressed, the lever returns to its place and the purge falls from the bowl into a small tank that must be checked and the remains removed periodically.
Without neglecting the extrusion system, highlight the inclusion of a double filament detection system. One at the filament entrance in the enclosure and that will allow the detection of jams and another in the head to detect lack of filament.
We have a double layer ventilation system, while in the head we have the main system focused directly on the tip of the nozzle while on the side we have an auxiliary fan that will allow us extra ventilation for those filaments that need greater airflow.
A trend that we see with the inclusion of these auxiliary ventilation systems is that they are usually quite noisy, in addition to having only one located on one of the sides, not always being optimal and sometimes causing certain artifacts in our pieces. In addition, in the case of the QIDI Q1 Pro, the design of the air nozzle leaves areas where it does not reach effectively.
From the back we have access to the toolhead electronics very similar to previous models, again with some improvements regarding ventilation that we will show you later. To access these electronics we will remove 4 anchor screws to remove the protective housing.
Regarding the printing platform we have a bed with a house design where we have an independent double kinematics on both sides of it, with radial linear guides along with the typical spindle. According to the specifications we can reach 120º, which gives us a lot of freedom to work with technical filaments, although when using a 24v heater it takes a few minutes to reach certain temperatures.
The printing platform has powerful magnets that, together with an HF strap that gave us such good results on the QIDI X-Max 3, perfect to prevent warping and maintain a perfect adhesion of our parts without having problems when removing them.
Another improvement that we already talked about previously in this QIDI Q1 Pro is that we find a leveling system integrated into the structure of the printing platform.
Although not much technical information is available about it, it basically mounts a series of piezoelectric sensors that, together with the head leveling sensor, will allow the automatic adjustment of the Z-Offset when the nozzle comes into contact with the printing platform.
This Q1 Pro has also included a temperature management and heating system for the printing camera with a PTC set with a fan that will allow us to keep the printing cabin at about 65ºC. Something that with certain filaments will considerably improve the quality of our printed parts.
Also for the enclosure we have a fan for air recirculation which if we work with materials that give off odors or vapors we can print a modification that we will show you later to be able to use a carbon or HEPA filter.
Electronics
Regarding the electronics of the QIDI Q1 Pro we find, like other recent models of the brand, an all-in-one MKS electronics from which the Klipper host part and the printer are managed.
At the bottom we have an SSR, solid state relay, protected with a housing and that will power the heating system of the enclosure and in the final part of the review we will give you important information about this component.
All the main electronics are located on the back of the printer, removing the entire back panel, making access somewhat laborious. In the cabin we find the electronics, a 24v/360W/14.6A power supply as well as a couple of fans that we will talk about later.
In the control electronics part, as we told you before, an all-in-one MKS (MKSPI) adapted for this printer model, is the X-7 v1.0 model with an Arm Cortex-A53 processor of 64b at 1.5Mhz, 1GB RAM and a 32Gb eMMC (around 21Gb available) for the Klipper host part.
For the management part of the printer we have an Arm Cortex-M4 MCU from 32b to 84Mhz, we also have 4 TMC2224 drivers for the X and Z axes (double in this printer model).
Below you can see the diagram of the electronics of connections and pins that can also be accessed from the QIDI wiki.
On the back of the printhead we have electronics to simplify wiring and have some extras such as an integrated accelerometer for adjusting Input Shaper.
This electronics for the toolhead is also an MKS THR adapted for QIDI, which mounts an RP2040 MCU as well as a TMC2209 driver for extruder management as well as several outputs to control the leveling sensor, filament, etc…
In any case, I suggest placing a heatsink in the MCU, below the one that already has in the driver as you can see in the image we showed you above, which will allow us some degrees of extra margin in certain conditions that can avoid system instability.
Also in the electronic part we have a color touch screen with a proprietary interface that is quite functional, simple and with quite a few options… although we also encountered some problems during its use that will probably be fixed in future firmware versions. Another noteworthy aspect is the location and orientation of the screen, which helps to contain the size of the printer and, thanks again to the interface, it is very manageable at all times. I would like to highlight the filament loading/unloading assistants that have worked very well for us and are always appreciated since for an important process like this it is not always like this.
In any case, we would have loved to have a more KlipperScreen-style interface with some layer of customization that gives us more options/freedom.
We have an integrated camera which is not that it wastes image quality but it is more than enough for the management of prints and small time-lapses.
Firmware Klipper
If you follow us assiduously you will see that in our latest reviews this is an aspect that we give quite important, especially if we are users who do not want to depend on the service/support from the manufacturer who unfortunately tend to leave aside old models without support/updates.
QIDI mounts Klipper yes, but a customized and outdated distribution compared to the official version which limits us in features, compatibility and firmware problems/improvements.
The good thing about QIDI in this case is that it allows us access to a standard web interface, although outdated due to what we mentioned before, such as Fluidd. We can access this interface once we have the printer connected to our network and from a web browser (of a device on the same network as the printer) using the IP assigned to the printer http://<IP_QIDI> where we will have controls to operate and manage the printer.
One aspect that we have liked to see with the different QIDI updates in this section is the improvement of some aspects such as the use of modular configuration or comments on changes on versions, avoiding having configuration files that are a bit saturated with configurations, or the use of adaptive leveling (based on KAMP).
We can follow the changes and improvements that are being implemented from the QIDI Github for this Q1 Pro, just a better tip to apply new versions following the process from the printer or from the versions that we can download from the web and not from Github… We run into some trouble doing it this way.
Print test and use of the QIDI Q1 Pro
We’re coming to the end of our review, and now it’s time to put it to the test and see what it’s capable of!!
Once the machine is ready, it’s time to focus on the adjustments and one of the first steps is to go to our rolling mill to start generating our parts. In this case, we remind you that we can use QIDI Slicer which, based on PrusaSlicer with a customized interface by QIDI, has integrated profiles for its machines.
Although the experience with this QIDI Slicer is not bad, in our case we work whenever we can with OrcaSlicer, our favorite laminator and luckily we have base profiles for the QIDI Q1 Pro.
Following the OrcaSlicer wizard we will add the printer and go to the network connection options (WiFi icon) and in the Physical Printer configuration window we will select Octo/Klipper and we will put our <IP_QIDI>:10088
as you can see in the following screenshot, we will perform a Test to see that everything works correctly.
With this, we will have our browser ready to start generating parts and sending them directly to our printer from the laminator!!
In our case, we started our tests using the high-speed QIDI filament, but not before performing the basic tests that we have in our OrcaSlicer to fine-tune the basic settings of the profile that it carries by default.
After carrying out these tests and adjusting our print profile, we have obtained good results without extrusion problems up to about 250 mm/s... Depending on the type of filament and which have to be adjusted by the type of trace, an internal perimeter or fill is not the same as an external perimeter, even by the type of piece.
Taking advantage of the purge system and the excellent filament change and on-screen management macros, we did a lot of testing performing filament changes in the middle of a print as well as simulating filament supply cuts with various types of filaments such as PLA, ABS and ASA.
Changing filaments
The changeover process of having a good on-screen interface for these types of switches was to simply add the PAUSE macro in our laminator scripts to stop printing when required and manually change filament from the screen.
Time-lapses
Speaking of functionalities, the camera we haven’t talked much about. Among the functions of the built-in camera we find the print supervision options and another one that we are going to explain a little more in detail… Time-lapse our prints to leave our friends open-mouthed about how our works of art are created.
Or to see glitches during printing that never hurt.
The Q1 Pro has this feature that we will basically activate using a macro called TIMELAPSE_TAKE_FRAME
. In our case, since we don’t want to have to change settings in profiles to activate or deactivate it, we opted to automate this a bit in OrcaSlicer.
The first thing we did was, in our printer profile, adjust the Time Lapse script with this:
{if notes=~/TIMELAPSE/}TIMELAPSE_TAKE_FRAME{endif}
Basically, this script is going to look if our print profile, in the notes section, contains the word TIMELAPSE in order to insert the macro to make our captures.
In this way, you don’t have to maintain different profiles to manage whether or not we do time-lapses… All this, of course, is pending that OrcaSlicer allows you to have an option to carry out this process directly as if you have profiles from other printers. I’m sure they’ll be adding it shortly.
Once this is done, the operation is very simple, the laminator generates the calls to the macro in its gcode and our Q1 Pro will take the captures and assemble the final video that we will find access from the web interface from where we can view, download or delete these videos.
Filament tests
As always, we carry out tests with other types of filaments:
- PETG, it was relatively easy for us to print on this machine giving good results although fine-tuning the settings to find the right spot. Normally, PETG, which has good mechanical characteristics and is easy to print on any machine due to its temperature requirements, is a viscous filament and the condition, quality and settings usually avoid, for example, the adhesion of debris to the nozzle that can leave artifacts on our pieces. It should also be clarified that this filament has not been used for many months and although we store it, or try to, in conditions so that it remains in good condition, sometimes it is not always possible.
- ABS/ASA, as we did with the QIDI X-Max 3, goes perfectly with the Q1 Pro. The heated enclosure and the HF surface allow these types of filaments to be printed in a solvent way and with sensational finishes as well as being very resistant.
- PCTG, as with PETG we had to fine-tune the setup a bit to get good results.
- HIPS, another technical filament that we were able to test in the Q1 Pro and that we don’t normally use
- NYLON PA12, with additives for better adhesion and a filament in good condition we obtained an excellent result after a fine adjustment of the configuration.
- PA CF, like the rest, we had no problems except to spend a few minutes making adjustments to our laminator
We always like to make filament visualizers with some basic tests to see where to move in settings and on the other hand have them saved as a reference for them.
Taking advantage of the tests of this Q1 Pro, we also decided to make another filament visualizer, in this case more compact and with a storage system. The truth is that it has turned out great and we always have a sample of each filament for future reference.
Although we have only shown you a few examples, during our tests we use a wide variety of filaments and parts to try to correctly evaluate the performance of the machine.
AzureFilm Prime… Quality filaments
Something we always like to emphasize in 3D printing is that if we are looking for perfect results we must have a machine and settings that are as perfect and reliable as possible… But apart from this, it is also essential to use quality filaments in perfect condition.
The folks at AzureFilm sent us some samples of their new AzureFilm Prime range.
AzureFilm’s new range of Prime filaments are designed for those makers looking for a high-performance, high-quality PLA, ASA, ABS filament with:
- Excellent heat resistance, designed to withstand high temperatures are ideal for maintaining the integrity of our parts even in extreme conditions offering great durability
- Impact resistance, these filaments are designed to resist deformation, cracking or breakage due to impacts which will give our parts great strength
- Less deformation/shrinkage, normally when printing ASA/ABS is usually a problem during printing, deformation causing adhesion problems and ruining prints. The Prime range improves this aspect as well as providing dimensional precision to our pieces. Normally we usually print on this type of filaments (ASA/ABS) using a skirt to improve adhesion, with the AzureFilm Prime filaments we found that without this or in complex pieces using the skirts “ears” mode were enough to avoid the dreaded warping, although in this Q1 Pro we have the advantage of the enclosure with temperature control that always helps we have tried in other machines without it and even open with some Excellent results.
Of the AzureFilm Prime filaments we have tested, we find:
- ASA Prime, a type of filament that for us is exceptional for its technical characteristics of durability, temperature tolerance, dimensional accuracy as well as its use in outdoor conditions. A type of filament that is an ideal choice for use in demanding applications and high durability in environments that are not friendly to other filaments.
- ABS Prime shares similar characteristics to the previously mentioned ASA. In this case, AzureFilm has significantly improved an impact that many users don’t like about this type of filament… the smell that is generated during printing. In the case of AzureFilm’s ABS Prime, we have observed that it is drastically reduced.
- PLA Prime, an easily printable filament like PLA but with great characteristics as we mentioned before regarding its resistance to heat, impact and contraction. It is also designed for high performance with speeds of up to 300 mm/s, as long as your printer supports it clearly, maintaining that ease of printing and technical characteristics.
The result, especially with ASA and ABS, has been sensational where apart from the quality of these new AzureFilm filaments, the QIDI Q1 Pro has shone for its characteristics in these types of filaments
Final QIDI Q1 Pro rating
We come to the final part, that of evaluating the QIDI Q1 Pro and that, as happened with previous models, we see things to highlight and things to improve.
In any case, we would like to focus on this machine, due to the characteristics it offers, such as enclosure or compatibility with technical filaments and some interesting functions, and its price, it can be a great option for demanding users in this type of areas in which a versatile machine with a wide variety of work materials at a reasonable cost is necessary and that will require certain concessions in the final quality and finish of the machine.
We will not go into the aesthetic aspect, since it is a very personal issue of each one, but we will highlight that despite having a robust metal chassis, the plastic enclosure that looks correct seems a little far from the current trends where other normally more robust materials are used… and that, on the other hand, make the price of similar machine features more expensive.
It is a machine that we can obtain great performance with the corresponding settings and work with a multitude of materials, including technicians, in a reliable way… In this aspect, it should be noted that the extrusion system has given us better sensations and reliability than with previously analyzed models… A big slab that we had with them.
This is a note for our personal case in our shipped unit, the machine comes conveniently oiled and adjusted but… We advise you to check the tightening of the screws and personally clean and lubricate all the kinematics well once we have the machine verified and after the initial tests.
Checking screw tightening and cleaning/lubricating the kinematics is highly recommended after the initial start-up
The heating system, which is a great advantage in this type of machine, QIDI has decided to install a PTC heater of, in the case of the EU, at 220v with an SSR relay for its control. The problem comes from the fact that due to the type of heater the current/voltage passes through the radiator, something that can be potentially dangerous.
We have some mods on the QIDI wiki like this one, and we will have to make them in a filament that withstands high temperature, which will protect from possible accidents.
As we saw in previous models, the PEI/HF used has given us very good performance in general, but in certain materials the use of adhesive or laminator aids (skirts, rafts, etc.) is inevitable to help in those cases. Something that has not convinced us are the flaps or guides to place the PEI/HF in the correct position, since it is very easy for it not to be well placed in its place, affecting our impression.
Another aspect that has been improved, half-heartedly from our point of view, has been the location of the filament roll support that we now have an adapter to put it on the side of the machine.
And we say half-heartedly, because although it is an improvement in terms of usability, having it accessible and not like some previous models that had it in the back, the placement of this leads to the machine occupying even more… Luckily, though, we have community mods to improve in this area.
Let’s move on to perhaps the most compromised part of the valuation of this QIDI Q1 Pro… the software and electronics part.
QIDI has continued to improve the machine management interface on its screen, which, although limited in some functions, correctly covers these… Yes, we would have liked the use of a more KlipperScreen interface with a layer of customization of course, but it is functional except for some bugs and certain slowness at times that I am sure they will continue to solve in future updates.
Although Klipper doesn’t natively have print recovery in the event of power failures, QIDI has it implemented in its system, which is great.
The reality, in our case we have not been able to take up a single impression in a totally satisfactory way, so if this function is something important for you… We advise you to accompany your printer with a good UPS/UPS.
Related to the power supply of the machine, we would have liked to have a power button on the front and not on the back, not only because it is in a difficult location to manipulate but also because the placement of the cable and the switch makes it difficult to manipulate.
Perhaps one thing that caught your eye throughout the QIDI Q1 Pro review is that we haven’t put much emphasis on the mobile printer management app. Although it is a very useful function, it is in development and has to be downloaded directly, in the case of Android, instead of the normal app store, so it is not advisable.
On the other hand, the application, although functional, is still an interface similar to the one we can find if we access the printer directly and the monitoring using the QIDI Cloud gave us some problems, as well as the online firmware update process, so these are functions that we hope QIDI polishes in future updates.
Klipper Enhancements
Regarding the Klipper system that the printer handles, and which we already mentioned at the beginning that it is a customized and not current version of Klipper, it can be in certain aspects a limitation to get the most out of this machine.
Given that the base is the same as in previous products analyzed, we are going to suggest some advisable improvements, taking advantage of the fact that we have access to the SSH command line of the machine.
Since basically the system used in this Q1 Pro is identical to previous models, we advise you to check out the mod guide we made for the QIDI X-Max 3. And we are going to explain below those that we apply in our case to the Q1 Pro.
- Time update, for us it is important because we will have correct estimates of printing times or dates/times of our printing history and so on. As the electronics do not have a battery to maintain it. Basically, we have two options to make these adjustments, which you can find detailed here.
- add MCU temperature report, something that will be very useful as you will see later, with this modification we will be able to see the temperatures of the host, the MCU of the electronics and the MCU of the toolboard. Basically we will add the following lines in the printer.cfg, we can use the web interface for this, just above the line containing
#*# <---------------------- SAVE_CONFIG ---------------------->
When we reboot we will get temperature readings from our interface.
### 3DWORK - Temperatures host + μcontroler
[temperature_sensor host]

[temperature_sensor mcu]
sensor_type: temperature_mcu
min_temp: 10
max_temp: 85
[temperature_sensor toolboard]

- Input Shaper, another essential improvement given that QIDI’s macros perform the process automatically and do not generate the graphs that can help us identify problems. You can explain the process in detail here. In our unit as the machine was adjusted, we found a lot of vibrations that the automatic adjustment of Input Shaper together with the default settings gave quite improvable impressions. And we include as a reference some improvements with respect to the initial state and once analyzed/improved through the graphs and the mechanical adjustment of the machine by adjusting the tension of the belts. By the way, the adjustment system of the straps is different from previous models and honestly… Nor is it a system that convinces us that allows a precise and simple adjustment of the tension.
Comparison of the belt tension test before and after adjusting these following the process that we can find on the QIDI-https://wiki.qidi3d.com/en/Q1-Pro/Maintenance/Adjustment-belt website
Input Shaper status after adjustments, with considerable improvements compared to the original values without adjustment. In any case, we were not able to optimize certain vibrations in the Y-axis.
Electronics Improvements
On the electronic side is where we have another negative point, despite the fact that we have not had as in previous versions high temperature problems in the electronics of the print head… that’s if the first thing we did was put a dissipative on his MCU to heal health… With the main electronics it’s been a different story.
As you can see in the previous screenshot we found random problems, if… both as well as the original firmware that came with the latest version available, and that they passed on to us when we went from testing with filaments that required heated enclosure where the system works at its highest performance.
Thanks to the basic improvements in Klipper that we suggested in the previous point, we had the temperature of the different components available and we were able to relate the restarts/failures to a considerable increase in the temperature of the main MCU of the printer’s control.
In the previous screenshot we can see errors for arriving at different temperature thresholds that we put until we found that 85º was the maximum temperature at which our machine was stable.
In any case, we will continue working to improve some aspects that you can see in the following image in which we basically check the operation of the fan that extracts air from the enclosure and that, if heated, directly expels it to the electronics area. On the other hand, just like we did on the printhead electronics, we added a heatsink to the MCU and the wiring wasn’t as organized and clean as we’d like either.
We decided to solve both problems by using the mod recommended by QIDI to add a carbon filter to that fan, but again we saw that it still left a large space where the hot air continued to enter the electronics area and we continued with stability problems. We also didn’t feel that the ventilation of the electronics wasn’t the most optimal considering the temperatures we observed during our tests. So we decided to try to improve all these aspects.
We rearranged all the wiring so that the wires do not go over the electronics whenever possible.
We redesigned the carbon filter to lengthen it to the outer lid so that all the hot air flow out of the machine directly. We leave you the mod published in Printables.
We also designed a stand for a 40×10 5v fan that would improve the airflow of the electronics, as well as being very quiet, and we repositioned the original fan on a bottom to make an airflow circuit. You can access these mods here.
Connection diagram for the mod to improve the cooling of electronics with a 5v 80×10 fan
We also took the opportunity to place a trim with the QIDI logo on the fan of the enclosure that, although it does not contribute much, makes the whole thing much more professional.
After applying these modifications to the machine we did not have a single fault or problem with it having the machine running 24×7.
Where to buy the QIDI Q1 Pro?
QIDI has its ownonline store where you can buy the Q1 Pro directly as well as its accessories and spare parts.
In any case, we provide you with some links to other reference stores:
this is an awesome review. on the mainboard, is that a USB-C port above the (1) on the left top corner??
Thanks JP!! yep is a USB-C connector acting as a HOST USB interface usually used to do some tasks like write on eMMC mainboard verdions. You can probably obtain more information if you search for MKS-SKIPR as this printer use a customized version.
