Zelrp + Linuxcnc 2.7.12 + THC 150

Hello,

day after day i try to configure Myplasm THC (150 mode) with my machine. First time i use Stepconf to configure 3 axis and all work perfect! But now i have problem. I connect pins:
Pin 10 UP
Pin 11 Down
Pin 12 Arc OK,

I don't use e-stop, chargepump or limit switch. I try "thc-toma" files but anything work. When I change pins in the file parport.hal and delete some "estop" information in the other files i can use F1, and F2 to start machine, but when i try move X or Y axis i have information "Drive error".

My first configuration Stepconf:

Thanks for any respond.

I think its failing before he gets to the Proma. I suspect the drive error is related to the values for

I've never used a parport but I think these should be around 5000 but I think the experts say to start at 25000 and come down.

Thanks for respond!

I have some information from Prokopcio about connection Myplasm (150 mode) to my mainboard. I connect UP DOWN ARCOK to Pin 10 Pin 11 Pin 12. Now i don't already have floating switch (i have switch but torch is too heavy and i must build something new).
I don't have estop or any limit switch.
How can i test THC?

I think i do something wrong when I edit hal file.

What I do?

First i download files from here: proma-elektronika.com/index.php/pl/porady/plasma-thc-linuxcnc

Next I try to run this, and on my screen i see Linuxcnc and in the right i see THC panel.
F1 doesn't work. I think "maybe estop?" I search something about estop and delete it. Ok now i can run F1, and F2.
Next I edit hal file "parport" and now when I try move something I see Drive error.

Pin config from Stepconf is here:

Error

Bad position in drive 1

Maybe thc-toma config is not for my machine? I can't change pins in my machine...

Pin 1 relay (turn on torch)
Pin 2 - 7 driver
Pin 10-Pin 13 Up Down Arc OK...
Pin 14 relay

What can I do else? I have 10 sheet 2mm and i can't cut this... is too hot ;/

I do all again. Now i can use F1 but when why try F2 i see "drive in emergency switch". I delete one line in thc.hal and now i can use F2. I can move Z. When i try X or Y i see "driver problem". But when I set the speed <1200mm/min i can move X and Y. Next small problem is revert X. I try something like this:

net StepX stepgen.0.step => parport.0.pin-02-out-invert 1
net StepY stepgen.1.step => parport.0.pin-04-out
net StepZ stepgen.2.step => parport.0.pin-06-out

net DirX stepgen.0.dir => parport.0.pin-03-out-invert 1
net DirY stepgen.1.dir => parport.0.pin-05-out
net DirZ stepgen.2.dir => parport.0.pin-07-out

I try connect the pin 13 (floating switch) and i do not see anything in LinuxCNC. All wires is ok because when I try to use stepconf and assign pin 13 to estop i can use that without problem.

Thanks for help.

If we made it and all will be ok can I use this without floating switch?

Now already work! All the time I must learn... I have only two problems. First: i have velocity 100 but speed more than 800 have error... Second is something differrent. When I have too curve plate and move X and Y axis i switch on floating switch. (without burning). What can i do to move torch to up? (floating switch is on and i can't do anything).
