Reseting the Z height with THC
« on: May 15, 2015, 11:27:30 AM »
When cutting a row of small part I'd like to adjust the Z height to what the THC as decided was .06 inches off the last cut instead of use the standard probe/limit switch function. I thought inserting "G92 Z0.60 right at the end of each cut would do the trick but it doesnt seem to be working. Below is a section of my code. What am I missing?

This should work BUT if you are loosing the Z positions then you are stalling the Z motor under THC control . You need to slow the Z down some so it does NOT stall.

That did it! Just had to issue G92Z0.06 right after M5 instead of before.

Thx much.
