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?
