Can anyone help me. I slaved my a to the y axis but the motor s are not syn exactly the same. I increased the the denounce , I lowered my acceleration it seamed to help but not completely. I am using mach3.

Hi,
de-bounce is noise filtering for input signals and has nothing to do with outgoing motor signals.

Are the motors and drivers the same?

When you say 'out of synch' what do you mean? Do they rotate at the same speed? Does one get ahead of the other and if so how much? Does the difference keep
increasing?
