z plunging while using tangential knife
« on: June 02, 2016, 03:10:54 PM »
Ok I am still using Mach3 Rev 3.042.020
i have used this for some tangential knives in the past and had no problems.
this machine also has an atc on it
just made a simple square.
knife turns correctly for the cuts like normal.
gets to a corner, lifts, rotates, plunges to depth
then as the line is being cut the z also starts plunging
gets to the next corner
lifts, rotates, etc
it is random
sometimes after first rotation, sometimes after second or third

Does the Z axis DRO indicate this unwanted plunging during the line cut ?
