Usb smooth stepper

Yes no problem. If your tearing belts apart then something was very wrong. 2 ballscrews and 30Kg is nothing for belt drive. I use this method all the time with 2 x 20mm 10mm pitch ballscrews and never have any trouble with belts tearing.

Thank you for your help.
I used some old XL 10mm pulleys and belt I had from another project, the belt reinforcement teared from the inside. Will buy some HTD5 and give that a try. Do you use pulleys with set screws? If so, do they keep tight over time, the ball screw ends are Ø12, or do you use keyway connection or flatten the shaft where the set screws sit?

Regarding gantry squaring with dual motor drive - I understand that is a feature controlled from within mach3. Wouldn't it be possible to use mach3 to perform gantry squaring on CSMIO-IP-M also?

No, gantry squaring is handled by the motion controller, and the IP-M doesn't support it.

It tells you that on this page, right below the comparison chart.

Ok, thanks. Will go with belt synced dual screws on a single stepper. I use 2 screws Ø20 with 10mm pitch, length 1900. Will use the machine for plywood cutting. Plan is to use AM882 drivers on 70V. Any recommendation on stepper motor that will handle this setup allowing high feeds? Also read somewhere about stepper drivers running from mains power supply, should I consider that? - any examples on these kind of drivers?
