The well-known company Bigtreetech<\/strong><\/a> returns again to the market with another powerful electronic board called BTT Octopus<\/strong>, which outperforms its little sister, the SKR GTR<\/a><\/strong>.<\/p>\n\n\n\n

Of all the high-performance electronics that have passed through our hands in 3DWork, such as the previously mentioned SKR GTR<\/a><\/strong> or the previous SKR Pro, we have to say that the BTT Octopus<\/strong> has been one of our favorites, without any doubt.

Brief introduction<\/h2>\n\n\n\n
\"BTT<\/a>
BTT Octopus<\/figcaption><\/figure>\n\n\n\n

Scratching the surface a bit we can discover that this “monster” has 8 replaceable drivers<\/strong>, 6 PWM fans to use with different voltages (thanks to its integrated DCDC) and even an Ethernet connector with support CAN Bus, to further expand its incredible features.<\/p>\n\n\n\n

In addition, it is worth mentioning that its compatibility with different firmwares makes it the perfect solution for the most demanding makers on the market.<\/p>\n\n\n\n

I sincerely believe that any user of a “CoreXY” machine will consider it to be the ideal board. Especially if you have a Voron 2.4<\/strong><\/a>, a BLV<\/strong><\/a> or a VCore3<\/strong><\/a>, being today the best machines in this format.<\/p>\n\n\n\n

Where can I buy the BTT Octopus?<\/h2>\n\n\n\n
\"-<\/figure>\n\n\n\n

You can buy the BTT Octopus<\/strong> in the Amazon and Aliexpress marketplaces, as usual. However, here we leave you the direct links to the components that we reference in this article.<\/p>\n\n\n\n

If you use them, the price of the product will be the same as if you log in regularly, but 3DWork will have a small commission left. Something that will help us support the project and continue generating content.<\/p>\n\n\n\n

Diagrams of the BTT Octopus<\/h2>\n\n\n\n

Before starting with the different diagrams and schemes, it is important to mention that there are to date 2 versions of the BTT Octopus<\/strong>, specifically versions v1.0 and v1.1.<\/p>\n\n\n\n

The most notable differences between the two would be a change in the polarity of the fans output, a problem in v1.0 with the LED of the SD reader and that the MCU regulator and the endstops have been replaced by another model. In any case, none of these cases affect in any way its operation or its current performance.<\/p>\n\n\n\n

As always, you have at your entire disposal on the manufacturer’s official Github the BTT <\/strong><\/a>Octopus manual<\/strong><\/a>, from which we recommend reading it due to the interesting information you can extract about this electronics in question.<\/p>\n\n\n\n
