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.

Looks like I am making some headway , I changed the Z Need Pulse back to 6400 from the previous setting of 1700 and thats turning the motor much better so will put it back together and see what happens. |
