MK1 Steel router build log 1500x800x200

For now a 2 stepper x setup looks more convenient from a mechanical point of view.
2 short belts.
lots of bed space

That's what I use you can run them 1.5:1 or 2:1 I used 3.1Nm but with 1610 screws motors from https://www.cnc4you.co.uk/Stepper-Mo...YGH301B-Nema23
with am882 drives from China

I do have a nema 23 4Nm on my mill but don't see a difference in them

Dear Boyan,

Not sure iam really clear what your preference is.

Do you mean use a single motor on 2 belts solution?
Mechanical advantage is :
- Y axis can not get out of alignment easy?
* disadvantage idler pullys

or

use 2 motors and solve alignment in the homing sequence by electronic controls...
- Y axis can be aligned easily that way.
* Some (cheaper) controls dont do gantry squaring sequence.

if you are experienced with belts, know how to tighten properly long belt, know how to align all components then go with 1 motor and belt system. If you dont have the space, have a suitable controller board, go with motor each side. At the end is a question of convenience.
