Hello,

Using Mach 3.

I'm sure it's something obvious but....

If we rout several copies of the same item, the zero axis does not appear to stay at the same reading between copies - is this correct behaviour?  It means we have to zero the Z axis for each copy (we have a zero plate on the router)

I'm a bit of a noob, so is this how it should be?

Thanks!

Hi, GVP

If it's stepper motors and losing steps on Z-UP (each part, deeper cut) Reduce the Velocity and Acceleration in Motor Tuning Z axis,or

reduce F speed for Z.

More Info would help

See if this Helps, Chip
