valid arc lost program is paused

So you mean editting the torch off before end path rule in the plasmac.tools file, not the post processor file? I am sorry to ask but how I can do it?

Sorry, I cannot help at the moment, my SheetCam tried to update itself and now it is trashed...

A couple of different things you could try from this pic you posted:

#1: in the left hand image for the torch enable rule check the include leadout box not for torch disable

if that doesn't work, try:

#2: don't enable the overcut in the right hand image

Either one may or may not work, I cannot test it here.

I tried the #1 and it WORKS like a charm. I admire your attention to details! I appreciate your help alot. Thanks and have a good night!

Hi! I have a similar problem. My problem is when the cut is finished and the part falls away my arc ok will halt. Can I pause the arc ok for the last couple of mm? I also have sheetcam. I heard that I should avoid having lead outs and that I shouldn’t look into this. But I heard that I could have rounder holes if I use overcut and therefore want my machine to ignore the last mm of arc ok. Is there a command for ignoring arc ok?

I believe you are looking for this:

If you have a newer config, it's pre-populated, but commented out in custom.hal.  The default is 0.0s so do change it.  I have been using 0.1s without incident for quite some time.
