Say it's the Y-axis, if you move it from the origin (0) to a set point does it move the correct distance? If you then move it back to the origin does it end in the exact location it started?
If so, it's the configuration.
Here's why. The stepper has fixed increments, so for it to run slow it is either losing steps (could be due to mechanical, motor or driver fault) or being sent slower pulses. When steppers lose steps they do not recover them unless they have encoders (rare) so it will be short of the commanded distance.

I think i got confused with your questio the y axis versus the lift...The motor is controlling the lift , the other two motors to control X and Y axis I believe work fine, and when I hit the origin it goes back to the upper right side as I have it set that way in the configs. I should also note that in the manual the machine configs did not work well with the machine therfor the previous owner had made the values lower then what it said in the manual, so prior to making more changes I had written down what the previous owner had for settings..I could go back to those original settings but I will wait to hear what you have to say , that might do more harm to the settings that I have already messed around with.
Hi Zax, it is the table lift and im sure your right on target with what your saying. I should have known better if it aint broke dont fix it..I was trying to make axis adjustments..To answer your question about the y axis distance of travel yes your correct it ends in the exact location it started...So now a matter of resetting the machine config or have a recommendation what I should do?
