I'm in need of help with my plasma cutter. I have a EZ Router CNC 4x8 Table, Thermal Dynamics A40 Plasma, and a EZR1000 THC (MP1000 re-branded)
A while back I lost function of my THC so I posted hoping to find some help. This is what I posted in the EZ Router Forums but I have gotten no help so far. I figure maybe its more of a Mach setting problem...
"So my table has been up and running well for the past few months, thanks to your guys help and specially the help from TerraWombat.
Recently though, I lost the use of my Torch Height Control. I'm not sure how to go about diagnosing the problem. I'm not a 100% sure but I believe it stopped working when I reinstalled Mach 3. So I have a feeling that I just lost a setting somewhere
Last night i printed out the Mach 3 Manual and went through it page by page with no fix. I took some screen shots of my settings and program run screen to see if hopefully someone can notice something wrong. From my understanding of how the THC works, I should see voltage stay about the same during a cut. because mine is inop, I see a change of about 50amps as the torch gap increase/decreases. To me this says that my sensor card is seeing the change and the computer is just not compensating and moving the z axis.
One thing I noticed is on my program run screen is "torch on/off" is not lit up. it is either off or if i click it, it blinks green. when its blinking and i run a program, the torch moves to the first pierce, fires, then doesn't move from those coordinates.
When running a program and watching the diagnosis screen, i get no lights on the "torch up" "torch down"
under config > milling options, I also tried "allow torch up/down control even in not in thc mode" and that made no difference either.
So at this point i'm not sure if im just missing a setting or if i have another problem. any help or ideas are appreciated."
