I am using GT2 belts and pulleys on my Z axis that has 10 inches of vertical travel
No problems so far
I have the Probotix drivers set up for 16X and the motors are 200 steps - 1.8 degree
One single Nema17 is driving two drive shafts that have two belts and four GT2 20 tooth pulleys
The weight that this motor has to lift is not huge
My X axis and A axis are fairly light
I have set up the Z axis motor in Mach3 to handle this situation
