So I have a Crossfire Pro with THC. I was able to stumble fumble and finally get it assembled. My cutter is a PowerPlasma 52i with CNC port. I followed the information available on the site and soldered together the communication cable. I am able to get a voltage from the THC controller, reads like 59v I believe, I will double check when I get home and edit OP for correct reading. I had to use sheetcam as fusion 360 would not work on my PC for some reason. Fire control will load these and trace the program but the plasma cutter WILL NOT activate and cut. I am at my wits end on this. I have turned away a bunch of potential work on this and need to get this sorted.
First the THC has nothing to do with the torch not firing. Lets get the torch to fire first. Are you using a hand or machine torch? What is you air set at for cutting? Are you wires to pins 1 and 2 on the CNC port? Did you check the torch fire relay in the control box? does it click when you command the cnc to fire?
@mechanic416, Firstly Thanks for the reply. I should have stated that I can manually operate the plasma cutter without trouble.
Can confirm wired pins 1 & 2.
For the relay everything looked correct, how can I double check this?
I cannot confirm a clicking when trying to manually fire with the program. I will check this shortly.
Where is the cable that is connected to pins 1&2 plugged into? It needs to be plugged into the torch on/off port on the electronics enclosure. For some reason people think it gets plugged into the VIM box.
Also, it needs to be fully plugged into the port. Some people have difficulty getting it pushed all the way in.
well… now I feel like an idiot. That was it. Swapping which cables went into the VIM and Torch on/off ports fixed the not firing issue.
I was able to successfully cut a test coupon, the entire program was not successful due to the settings of the program loaded (pierce delay too short) but I am going to take the victory by inches at it is.
Now the issue is the THC. it is reading a solid 0.0 volts now.
I run an Everlast 82i. Its wired raw voltage and has never skipped a beat. I don’t believe you will void the warranty either. If Everlast would update their cnc board we would not have to do this. Just REMEMBER the work lead is the red wire. Torch is the black.
Just follow the instructions on Langmuirs site.
