General Mach Discussion / Losing zero ref - related to feed rate changes?

« on: September 24, 2006, 03:24:00 PM »

I have a question.  I am using mach2 and a taig mill.  I am cutting wax for jewelry.  So far I have set up the machine and it has worked reliably for several pieces.  On the last one though, it abruptly changed its zero reference during roughing.  I had one other time when it lost reference during milling.  The only thing that ties these two instances together is that I was chanigng the feed rate via the Mach2 feed rate control during the cut.  I tend to start at a slow rate and increase up to a higher rate.  Or if it is moving to a new location (at the safe z height) I speed it up briefly.  Is this a problem?

I have also noticed that sometimes when I zero out the z height, the x and y reference changes.  Why is this?
