You can still double the torque with a 2:1 beltdrive on the steppers and have 10000mm/min rapids.

Uwe
what do you recommend as a pinion level transmission size


que me conseillez vous comme taille de transmission niveau pignon

I would use HTD 5M 15mm beltdrive for this weight.

Calculation can be done here easy:

Very nice, but put the smaller pulley on the drive and the bigger one on the ball screw...

No to gain torque to move the heavy gantry fast without stalling the drives.

So I will have to make spacers with the right diameter

Du coup je vais être obligé de fabriqué des entretoises au bon diamètre
