Quick questions folks
p
Just modelling up the Z motor mount plate to convert over to a 2:1 belt drive. Are you guys just running a pulley on the unsupported shaft of the stepper motor or are you adding some kind of additional bearing support? I'm conscious the belt is going to need to be pretty tight to avoid backlash, but worried about overcooking it and putting a tonne of side load on the motor shaft.

What have you chaps done?
