Hey yall, New crossfire pro owner here. It seems that my machine is having some trouble doing its first cuts. I am wondering if someone might have solved this issue before.
My set up:
Crossfire Pro
Razor weld 45 (plug and play THC)
using fusion 360 and fire control
I have done my full break in period and i went to cut my first parts and it unfortunately through me an error… The error is “IHS fail. the torch did not reach the material within programmed travel”
After some searching through the forum’s I can check the common issues off the board such as loose cables and set too high on the z axis.
I have also noticed that my lead screw for my Thc doesn’t seem to want to move. You can hear the stepper motor turn on when attempting to move it in fire control but it doesn’t seem to want to move up and down on its axis. I did the Thc test which had all of the correct voltage for it to work and ran through the Thc trouble shooting page to unfortunately no answer to the issue.
Has anyone had these issues when attempting their first cuts? If so what would be the best step to resolve this issue. Sorry i am new to all of this and still trying to learn…
Welcome to the forum. Hopefully, this is just a little bump in the road to success with your new venture into the CNC plasma world.
This might indicate that your torch is mounted too high. The typical travel for IHS is up to 5 inches. If it does not open the contact switch in the z-axis at that point, it will trigger that error.
Can you move the torch with the z-axis controls in Fire-control so the tip of the torch moves about a 10th of an inch below the top of the slats? If not, adjust the mounting plate so you have this travel.
There could also be binding in the z-axis (needs some lubrication or adjustment of the bearings) or more likely, slipping of the coupler to the z-axis screw. This would mimic movement that actually did not happen.
If the coupler is slipping, tighten the screws in the coupler but be careful, they do strip (if not the threads the head of the screw).
Worse case: You have a bad motor or the control driver board. If that is the case, you might want to start a case with tech support: Pro Support | Langmuir Systems
