Showstopper Plasma Cutter retrofit

update I turned ohmic probe off and it worked again.
If I try and use ohmic probe I get the same error.

There should be a .var file in your config folder that linuxcnc saves data (variables) in. Normally you never have to worry about it but sometimes when hacking into a config, it gets out of step with reality. Please delete this file and report back if it is still a problem

Try deleting the VAR file anyway. I will look at the ohmic hal file but there should be nothing in it to do with offsets etc.

Deleted var file and it worked again.

Hey guys,Still getting error messages for pierce height exceding z axis max limit.It's weird because it went away after deleting the .var file... But now I tried the same process and I still have the error. The only way I can get it to work is to disable ohmic probing.Also my pendant jog speed is really slow, maybe 100mm per minute. I have been looking in pendant.hal but I can't work out how to change it. It looks a bit different to the code that I find on the forums.
 

Does the machine have a float switch?
