Another plasma component...

I had problems with the plasmac way too but this is easy to solve. jog down to whatever zero point you want to use (eg. just under the slats) and in Gmocappy click on the blue touchoff Z button and set it to Zero and you are done.

So then jog back to the upper limit and note the Z DRO coordinates (say it is 4 inches). Next time you have to reset it, jog back to this top limit (or straight after homing and touch off the Z but this time enter 4" so there is no need to jog down to the zero point.

Just set the Plasmac probing height so that you are high enough above the zero point so you clear the material. You'll never worry about the Z position again.

Z moving down is always more negative and moving up is always more positive the actual numbers are relative.
The probe height is measured as positive from your minimum Z set in your ini file.
Don't use offsets other than G54-G59.3 or you will confuse plasmac.
When plasmac finishes it ends up at the starting Z position because it needs to clear its axis offsets so as Rod just posted start up high.

How are you guys tricking the arc ok. I have been trying to cut for the last few hrs and all I do is pop a hole and it alarms out saying no arc detected. My voltage looks good on the THCAD10. Is there a way to just delete that function?

I can see the text from a button that’s not there asking for arc ok voltage. But there is nothing there to click on.

I suspect that is hidden becasue of the Plasmac mode you have selected. Check the notes in the ini file. That might have been a bit my fault becasue I probably assumed you have an arcOK signal when I wrote my how to.

I looked through the plasma config files and found the callouts for buttons and found the options and option 1 had the arc voltage set to “hide”. I thought I had been told to be using option 1 but after looking at the config file I switched to option 0 and all is good. And it’s cutting sweet.
