problem with plasma cutter touch off control.
« on: September 25, 2018, 11:47:59 PM »
Hello all I am narrowing in on my home built cnc. However I am about to cry. I can not for the life of me get the touch off/ floating head to work properly.

I have a floating head with a limit switch attached to the probe input. I am using G31 and G92 in my touch off sequence. I have shamelessly stole the programming from this site. The machine will run down and touch off of the plate and set the dro to zero some times and some times not? usually it goes to -1.0 and then it will go to the next cut, and touch off. each cut it wants to raise another inch until it is out of stroke. I also have gone from version .066 to .062 with no help. What is odd is that it will sometimes runs some of the cuts right but never all. It is not consistent, the next time it will act up in a different spot in the program.

If you have seen this before or have a suggestion please help a brother out.


Frustrated Dave!
