Configure PlasmaC with only one BOB

thanks for this. I found the run panel where i can disable or enable the THC enable indicator.
The LED goes on and off when i change the radio button. But my relay doesn't do anything.
It is still on.
Where is the connection from the gui to the pin in my hal file? I don't understand this.

Hope you understand what i say?

Ok other question, how to enable or disable this circuit?

I connect the pin 16 out of my breakoutboard with this circuit.

The ohmic enable relays are still active when i start plasmac.

Have you connect the "DIGITAL OUTPUT" line to plasmac.ohmic-enable?

I don't know
I try to understand how this hal configuration works.
Maybe one can help?

For example. In the GUI i have the button PULSE.
Now i want to active my relay by pressing this button.
Whatever i wirte in the hal. I can't do this

I try this.

net test plasmac.toarch-pulse-start

in the hal file.

Also i write in the connections.hal

net test parport.0.pin-17-out

But this don't work.

Any help?

See Torch Pulse Time in the .ini file

linuxcnc.org/docs/devel/html/plasma/plas...tml#_ini_file_common

The torch pulse time is set to 1 sec.
Thats not the issue.

Is the relay connected to the torch-on signal in the hal file?
Do you have the torch enabled inth GUI?

Hi phillc54,
thank you for the quick reply.
When i delete my self edited code line in the hal file, then the control led turn on in the Hal-configuration panel in the pin section for pin plasmac.torch-pulse-start, when i press the pulse button in the gui.

But when i write this line in the hal file. the control led stay off.

net test1 plasmac.torch-pulse-start parport.0.pin-17-out

You don't need to connect to plasmac.torch-pulse-start, that is an input that is controlled by the button in the GUI.

You just need to have the Machine Power button on, the Torch Enable button on and press the Torch Pulse button, this will then pulse the output plasmac.torch-on. The pin plasmac.torch-on needs to be connected to the start input of your plasmac cutter in the <machine_name>_connections.hal fileI am guessing that ***YOUR TORCH ON PIN*** is parport.0.pin-17-out ???
