Hi everyone. I'm Paul. I have a Chinese 6040 router I bought a couple years ago and have always had a problem with the Z axis maintaining the correct elevation throughout the cut. Example: I start a model with the maximum depth of 3mm on the first pass. It will run for a while maintaining the 3mm depth. But after a bit, the spindle starts cutting deeper than 3mm, although the DRO in MACH3 still says it's at 3mm. If I let it continue to cut, it will soon be down to 10 or 15mm while the readout still says it's at 3mm. Anyone hear of this before? Any ideas where I can look for a solution?
Thanks for any help
Paul
