General Mach Discussion / Re: THC Setting Issue?

Thanks for the reply Sterling! The unit I'm getting is an older machine, only paid $2500 for it so a "couple grand" for a THC is kinda out of the books for now! I'll keep open for ideas, maybe come up with a solution yet! Thanks again, Brian

Hi Sterling,
      I am getting a Hypertherm HD3070. Is your THC able to work with that? I am using an Ethernet Smooth Stepper and I use Ohmic height sensing with a floating head. any thoughts?
        Thanks, Brian

I have a switch like this on my Z slide on my plasma table. The switches I purchased have three pins; NO (normally open) and NC (normally closed) and Line In pins. On my Z I have the switch pressed until it limits out so I used the NC pin. Then all my limit switches are configured alike in Mach 3. Wether possible to do that in Mach3, I don't know. I didn't try to figure that out because my switches came with either option. FWIW that my experience! Brian

I have a new Dell Inspirion (not sure of model) All-in-one that I run Mach3 on. It works great, although I wish for bigger "buttons" in Mach3 sometimes. Make sure it is "capacitive touch" not laser. Handles dirt better and is easier to control with touch only. Brian

I have a Proma THC and it keeps up to my machine when it works. I don't cut faster than 120 IPM, but if I can get Mach3 to move the Z the THC keeps up great! My problem is getting Mach to move the Z every time THC commands it. It work intermittently. What exactly did you setup in Mach? Where is the THC anti dive & THC Z rate settings? I've played with this for months already but maybe I'm missing something?!! I hope you find something that works reliably and keep us updated! Thanks, Brian

Hey thanks for the reply! This is a genuine ethernet smooth stepper mounted on an expensive Korean built BoB. One of my questions was, how can I use continuity probing without connecting signal ground to the frame/star ground? If not then what other way is there to probe top of plate with plasma?

Am I the only one in the CNC plasma league? Anybody else using a Ethernet Smooth stepper for plasma?

If I were building a plasma table from scratch, what is the proper way to set up the probe to reference the torch off of the top of the plate? Using a ohmic tip? I was reading posts on grounding and interference, and I figured out that 0V DC should not be connected to Earth/frame ground. So how do I get continuity for my ohmic tip to work if I can't connect to the frame of the table at all? I would like any input?!!

I also have that problem. When I type in my line of code that I want to run from hit enter and it always goes to line 100. Doesn't make any difference what the actual value I put in.

Hi! I have a CM-126-ESS (Ethernet Smooth Stepper attached to a breakout board) that I purchased on Ebay, see attached photo. I have an ohmic tip on my plasma table to probe the top of the plate. I ran a wire from the ESS ground to the table frame, and another wire from an open input to the ohmic tip. This works great except about every 2 hrs. of operation the input pin quits working. I just move the wire to another pin and reassign it in Mach3 and its good to go for a couple more hrs. As far as I know all the inputs are optoisolated, but is there another way to wire ohmic probing? Maybe use a relay? I don't know what else could be doing it. I tried backing up to some of the former pins that had quit a few weeks ago and they still don't work. Any body else using this setup for plasma? Thanks for any input!  Brian
