This page will always follow the author's open source agreement.
I will keep updating this tutorial.
⚠️WARNING
Do not hot-plug or unplug the connection cable between the BMCU and the printer while the printer is powered on. -> Risk of damage to the BMCU motherboard

2._purchase_list_of_all_materials.zip *Note：You will need FOUR 6x2.5mm radial magnets, they are in fact listed in the BOM sheet of the PCB, so the author didn't list them in the mechanical sheet.
They are VERY important and BMCU can't work without them
NO!!!
YES!!!
Please note that you must purchase RADIAL MAGNETS(Right photo).

¶ 370 version
The 370 version means that its motor uses a 370 motor(24v 6000rpm) instead of the original FF-130sh motor
Version 370 will work quieter and smoother.
Version 370 has a potential problem with five-pass explosions. (That's right. Explosion.)
The reason is that when the print speed is selected higher than 100%, the BMCU feeds the material faster than the speed of the extruder, resulting in abnormal operation
