That is a great idea… This is just 1/8" flat with 5-6 holes. Would you happen to know a good video I could watch to show how this is done? That would get me out of this bind I am in.
you should have the option to turn the thc off in firecontrol i am not around my table right now so i can’t confirm exactly how to do it. i dont recall ever cutting with my thc turned off so i don’t know exactly off the top of my head. you should be able to click on the thc green box at the top.
with thc turned off you should be able to cut it will set the cut height you have in your cam.

HEHEHE I have never tried it without either. I guess what I don’t understand is will the torch just set Z zero when it touches off the part or do I manually set Z zero like you would on a CNC Router?
it will work just like that on its own fire control will just not adjust cut height on the fly as they say.
10/4 I will definitely give this a shot in the morning. Thank you so much.

Hi, I just wanted to update you all on my issues. First off THANKS CAMRON. He helped out a very confused and frustrated person. After he logged onto my computer, we started running a few tests and we started unplugging stuff. After a while decided to unplug the SAFTEY SWITCHES and WOW the voltages went away. We plugged them all back in and tested each one by one. Y1 you little bugger you caused me hours of problems and several dollars in metal! I will say they are really cheapy switches but to have 1 of these cause a 50v interference I would have never guessed. Moral of the story is electric stuff can do very odd things. Bought new switches on Amazon to get by with for now and will make new brackets to mount better ones in the future. Gonna cut with no switches for a little bit.

So been having issues with our XR and bevels on 3/8 material; after lots of testing, found that with 0.06 cut height set in post (using Fusion 360), it was actually cutting closer to 0.16".
Ended up discovering that the IHS springback (and the 0.02 hardcoded backlash comp) post compensation feature is actually compensating with Z+ not Z-. Pretty sure that’s a bug as that features should be compensating for the sensing delay caused by the IHS contacts springing up as the torch moves up during a pierce, making it move too high.
Anyways, easy solution, just put a “-” in front of the IHS springback number. In my case -0.03 is dead-on perfect. (-0.02 of that just cancels out the backwards backlash comp, and actual IHS springback on my machine is right at -0.01") Smart-voltage is dialing in nearly exactly where Hypertherm says it sholud be at recommended ipm. This way you can leave the cutting height at 0.06 as was intended with those compensation features.
Devs am I on the right track with my thinking that this is a bug and the IHS number (and built-in backlash) should be inverted in the post, compensating to Z- instead of Z+?
What I do is just edit the G-code with note pad and remove the 0.020 backlash. Then when I cut I pause and measure then make the needed adjustment till I get an actual 0.06 cut height and that gives me what I need to subtract from the cam setting.
For instance my setting in fusion is 0.06 cut height but I measure a 0.08 so I would subtract 0.02 from the 0.06 and end up with 0.04 so I know going forward that I always set my cut height at 0.04 to get the 0.06 I need. It has worked flawless for me.
Also if you edit your G-code with note pad before you run it you can change your IPM or pierce delay or even pierce height then just save it and your good to go
I use the edit a lot when dialing in my cuts makes it way easier than going back through the whole cam process.
