Gmoccapy - A new screen for linuxcnc

ESTOP is only to immediately stop moving mechanisms in an emergency.
Do not use it for anything else, and after use it, the machine is only suitable for re-homing.
In this situation, the discussion of how the state should have a signal after the withdrawal ESTOP makes no sense.

thanks for the reply,
I found error in its own configuration .hal file,
there found the right way to connect an external ESTOP.
I apologize for the false alarm.

Hi,

I am wondering if the Gmoccapy plasma screen is set up to work with a Mesa Thcad.

I am setting up a Mesa 5i25 and 7i77 with a thcad on Axis, and have it close to correct, but I would prefer to use Gmoccapy.

I have looked at the wiki, but am still unsure what needs to be done use Gmoccapy plasma.

Where is the file that takes all the settings from the main screen and calculates them into the the proper Z axis settings? Also, what type of a file is it?

Thanks,
Todd

Hallo Todd,

gmoccapy_plasma is mostly a normal gmoccapy screen with some special embedded tabs, so some controls like spindle and coolant are covered by the new panel for the torch control.

The additional panels do have there own hal pin, so they can be connected to every existing hal pin, so MESA should not be a problem.

The expert for plasma is indeed Marius, he did also make a comp for THC, sure he will read this and give also his comment.

You can find all relevant files in

/configs/sim/gmoccapy/gmoccapy_plasma/

Hi Todd
Norbert is correct about the Mesa card. You can use many variations of THC control.
With the Mesa THCAD I use two components. The first one look at the voltage that comes from the THCAD and compares it to the THC Voltage setting on the screen. It will output a UP/DOWN signal that is coupled to the THCUD component ( already in the distro's). This component will control the Z axis to follow the material at the correct height. This method requires you to make use of Gcode to control the torch actions.

There are many settings on the Plasma screen but not all are needed for every system. We have included many parameters in order to allow users to create a very comprehensive control system. Many systems use a hardware THC and then it only makes use of Gcode and a simple up/down signal setup. You could also do the whole THC control in a component if you use just the THCAD. It al depends on how much effort you want to put in.

I have been busy with a very comprehensive THC controller in software for some time (to many concurrent projects ) and I hope to finish it soon in the new year as my own plasma machine will be done by then. I will make use of all the settings on the plasma screen as I am only using a voltage input similar to the THCAD. The rest is done in the component without using Gcode. The M3 is remapped in order to allow me to control the sequence of events of the plasma.

Let me know if you need help on setting up the system. I suggest that you read up on the wiki about plasma procedures. I have put a lot of information on there that could be useful in understanding the process.

Hello all. I seem to have gotten an error after some updates that I can't track down, here are the 2 error sceens I get when trying to open. I have made no changes to the python file in these areas.
