Working on a larger scale printer, Using RAMPS 1.4, and since the z axis already can handle 2 motors, I figured why couldnt the x & y?
So I built a simple rail system using 2 x motors driving belts. it does seem to work, however, at higher speeds it tends to "grind" on direction changes. Not a belt skipping, but its almost like the motors are magnetically becoming uncoupled. the funny thing is I can run it with 1 motor and its "better". So im thinking theres some backfeeding going on between the motors - kinda like when you turn the reprap z axis and the other side turns.
Is there any way to isolate these motors? Id really like to use 2 because of the carriage weight.
Or - at very least a diffrent type of controller with isolated steppers that can be "programmed" to both be x?
Thanks!
