You may find the Mendel assembly data sheet useful during assembly.

Top circuits

M3 nuts are used as spacers to elevate the boards slightly. This will help get your wiring neater later.

RP parts



Stepper driver PCBs are elevated from the sheet by two washers.


The power and USB connections are held on by two 40mm M4 cap screws with their heads under the board pointing upwards. First secure the XLR male connector using two ordinary nuts and washers. Then add the USB board (no washers underneath) and secure that with nylocks and washers on top.
