*Note：You will always need FOUR
6x2.5mmradial magnets, they are in fact included with the AS5600 chips in the BOM sheet of the PCB, so the author didn't list them in the mechanical sheet.
Some of the finished PCBs do not come with this magnet. They are VERY important and BMCU can't work without them. You must purchaseRADIAL MAGNETS.
NO!!!
YES!!!
¶ BOM for PCB
Currently, all BMCUs use the same PCB regardless of motor version.
PCB BOM sheet download
¶ If you want to try the typec version you need to:
- 4 additional 16p typec vertical components
- Purchase the CH340X chip instead of the CH320V.
- Print the base designed for the C-port
¶ BOM for mecanical parts
130 version :
Mechanical Components BOM sheet download
370 version :
to do. for now see below
¶ If you want to try the 370 version you need:
- 4 x
370 motors(6000 rpm at 24v) instad of original ff130 motor - 4 x
0.6x4x15springs - 4 x
0.6x10x25and 4 x0.6x10x30springs (different versions of the structure may use different springs so maybe buy both) - M3x16 or M3x18 self-tapping screws
- 242A gears no longer required
- (Optional) Metal gears : 8 x 0.5-mod 18-tooth metal gears, and 4 x 0.5-mod 8-tooth metal worm gears
¶ Notes
-
You will need 4 sections of ptfe tube for connecting BMCU and the printer extruder. Recommended length is 60cm/each , at least 50cm are needed.
-
You will need some transparent, colorless filaments for light guiding, only 4 of approx. 10 cm are needed so maybe no need to buy a whole row.
