The F for feed rate does not work when probing for material, so you need to set the correct speed in the .ini file for AXIS 2 under max_velocity.

Regards,
Tom

The F feed speed works for everything except G0, G33, G33.1 and G76. There is no ini setting for probe speed.

For example my plasma touchoff subroutine:

Hi, Tom/JT.

I changed the max-velocity in the .ini file and also as per an earlier post by bubels I uncommented a line. (the Z-axis is controlled by thc.hal and not via G-code in the case of the Toma THC)

linuxcnc.org/index.php/english/forum/49-...works?start=20#50427

The Z-axis is probing correctly now.

I also cut a warped plate and it appears that the THC is working correctly.

A further question I have is if there is a way to switch off the THC when cutting small holes and arcs (via an M command?), or is this handled in the thc.hal?

Ziggy

Hello, i was trying to include the proma THC module (Up/Down/ok) in my working gmoccypa plasma cutter, but it doesn't work.
Two weeks are over and my nervs too.

I use linuxcnc 2.6.9 and the TripleBeast.
gmoccapy is working, but i have absolut no idea how to install all necessary THC parameters

In the machine.hal is:

net MoveUp <= parport.0.pin-10-in
net MoveDown <= parport.0.pin-12-in
net ArcOK <= parport.0.pin-13-in

and now????

I googled for days and days:
There is a THC configuration for EMC from Proma.
proma-elektronika.com/index.php/en/tips/plasma-thc-linuxcnc
But that doesn't work too. There is no F1 (EStop... WHY???) possible and the syntax is totally different to gmoccapy. So i give up.

wiki.linuxcnc.org/cgi-bin/wiki.pl?Torch_Height_Control (broken links)
wiki.linuxcnc.org/cgi-bin/wiki.pl?Gantry...e#Homing_HAL_Control (doesn't work, No_Force_Homing=1)
And so on...

Who could give me a hint?

This really doesn't have anything to do with Gmoccapy... so far.

Did you load the thcud component in your hal file?

JT

No, i have heared about that. The docu means that is for Mesa cards?
It seems that i have all the needed files...?
I downloaded that:
wiki.linuxcnc.org/cgi-bin/wiki.pl?Gmoccapy_Plasma

Now it works. But like a mill. There is no THC control. I think it is not ready or something is missing.
I took three ref switch pins for Z-up, down and arc ok.
I can see the signals (MoveUp, MoveDown, ArcOk) in the HalShow.
If i try to insert this as a hook in signals.hal or my-machine.hal then the signals panel and/or the plasma panel disappears.
And nothing else happened.

At the moment i would be happy if it stops without ArcOk signal....

If i install thcud i will crush the actual constellation and i have to install the 9th or 10th version...?

Maybe someone else can help, I don't have a clue what you are talking about.

That's my problem. It is to easy to explain.
At the moment i only want to control the height of the plasma head.
I have a THC controller with two pins with up and down signals.
It is connected with a triple beast.
I can see the signals in the Halshow.
But i have no idea how to connect with gmoccapy (button up/down ?).

What is a "triple beast"?

Can you try and describe what you want to do, I still have no idea what you want.

The triple beast appears to be some kind of device that is controlled over the network...

What signals exactly can you see?

JT

The Beast communicates via parallel port (printer)

The most needed parameters are:

net MoveUp <= parport.0.pin-10-in
net MoveDown <= parport.0.pin-12-in

I can see in HalShow both signals MoveUp and MoveDown and that they work on contact.
But i have no clue how to hook up...

I have no clue what you want to hook the parallel port input pins to? Do you want see a led change state as the input pin is toggled from the beast?

JT

Hmmm, that is difficult to explain.
LinuxCNC is working in default with the parallel port pins.
The pin 10 is connected with a "MoveUp" signal
The pin 12 is connected with a "MoveDown" signal

So forget the tripleBeast and THC module and so on. It is to easy.
I can see in HalShow both signals MoveUp and MoveDown and that they work on contact.
My question is how to hook up that signals in LinuxCNC (gmoccapy plasma)?

What do you want to hook the signals to in gmoccopy? Keep in your mind that a parallel port input pin can only be connected to something like a led not to a push button on the screen. This is why I stay confused to what your trying to do.

Can you just say:
I want to push a button on my screen and make the thc go up.
Or
I want the thc to turn on an indicator on my screen when it is moving.

The first on would use and output pin and the second one an input pin.
