I ran the THC test and voltage is within spec based on that. When I start a project with THC enabled the torch crashes into my material and never fires. I have a voicemail to support but thought I’d reach out here until I hear from them or hopefully can solve it prior. It is freshly assembled using a Hypertherm 45XP with Langmuir CPC attached. I can generate a straight cut or design without THC enabled and it works just fine.
Any ideas or items I need to check. It seems like the torch thinks the Z 0 is much lower than it is or the THC just isn’t sensing the material.
The THC doesn’t sense the material it reads voltage when torch is on. Sounds like a sticky ihs switch. The ihs switch is behind the lead screw on the z axis makes sure it isn’t touching the lead screw.
Are you getting any error messages?
Could also be programming error. Do you have the correct post processor?
I am using the post processor from Langmuir for FireControl within Fusion 360. I believe you may be right about the IHS switch posting a photo as it looks like it’s in constant contact if I’m following what your saying.
I would say IHS not THC is your issue. If you move the torch up and down manually there is a “light” on the bottom of the firecontrol screen that should change status when that IHS switch makes or breaks. My guess is your IHS switch is not signaling the control box that the material has been contacted.

Here are my errors. I wonder if it’s thinking my material is much thicker than it really is. I’ll have to try and generate the nc file again. I am accustomed to generating designs in mm from 3D printing and everything in CAD/CNC seems to favor inches. I will see if that helps if there aren’t any other suggestions.
Phillipw hit the nail on the head or the IHS on the lead screw if you will. There was a small brass tab on the back side that was touching the lead screw. I knew it was but assumed this was normal. It either came that way or happened when I moved my Z higher than I should have after getting everything together. Thank you everyone! I’m a little disappointed no return call from Langmuir support after leaving them a voicemail, but all’s well that ends well.
