hello Ritch,
Yes, I miss cut's, while the X-Axis walks out of the material during the Z move, as if a taper is requested.
Not only physical, bud also the X-DRO, as TrevorH wrote.
During this pass there is no cutting material.
Obviously the program keeps count of the passes and the infeed's
The next one, when it is not walking away, takes the new value, and makes the next cut, witch will be the double infeed.
If only the axis would move by it self, and not the DRO then I would think about noise pulses.
As a retired Electronic engineer, I can think about noise, while I don't use screened cables.
Close to the X Steppermotor are two cables from a measuring device.
For me as a Hobby metalworker the problem is not very serious, so, don't stay awake about it, but it would be nice if
everything would work in the end.
Rieks
