Pals,

I have been building machine and never seens such a wierd issue, continuous XY Shift.

Its a CORE XY mechanism, I tried all common ways to trouble shoot steps skipping, but nothing gave results.

Can some body suggest to fix this.

So, what methods did you try?
Are the motors skipping steps, or is the problem mechanical?

Its mostly the motors, I dont think its mechanical

Check your stepper voltages.
