X Axis motor and belt adjustment query
Hi
I have built my Mk3s and could not get the motor pulley/belt to run without the belt scraping on the orange housing. The gap between the pulley and motor is <0.5mm.
Even if the pulley touches the motor the belt still hits the plastic. I have resorted to fitting washers to move the motor back. Anybody else had to do this? 
Best Answer by Neophyl:
You have the pulley on back to front. The 'thin' rim section should be towards the motor.
