I am using mach3 with machblue.set.
I set up my probe and grounded the mill head so that the tool tip could activate on my probe plate. When I activated the probe ... it went down to touch and when it made contact ... it tried to go down instead of retract the standard distance? I had set the thickness of my probe plate as a positive number.
What is going on here? Why did it go down, touch off, then go down more instead of retracting. Sometimes it works correctly.... sometimes not. I don't think I have any noise on the lines and even if I did ... would this happen?
Could relative vs absolute gcode setting have anything to do with it?
Any feedback/advice appreciated.
