You should only need to calibrate your arc voltage electronics/display once. Of course if you change any of your components you will need to do it again. So don't leave your extension leads connected, you don't need to.

What you will need to do is a simple line test every time you use a new material or cutting conditions to figure out the correct arc voltage for your machine to use for the THC set point. I am still not sold on the auto volts method, it requires absolute confidence in your initial cut height.

This is really old news. You are already using a HAL_Button widget for the torch enable/disable button. I bet the reason someone came up with the HAL_LightButton widget is to get around all the problems with getting all the themes matched up in each window. I think this widget functions in some theme neutral fashion. I am only suggesting this because I have seen others use it for color changing buttons with success.

I looked through the read me and did not see any gcode commands to turn thc on and off. Had corner locking problems with small triangles as well. Right at the tip when it reverses direction the torch dives and hits the sheet.

When you say it's always on do you mean that the LED is showing that it is locked.

Cheers, Phill.

Yes if I select the check box then the light is on once I start cutting. And the Z does not adjust as it cuts. So if there is a bow to the sheet then it trips out as it triggers the float switch or stretches the arc and the cut is really bad. I have not updated since I got it working with the new install. Was kinda scared to mess with it and be down.

Could you post your ini file and a gcode file that shows that behaviour.

Cheers, Phill.

I have pushed an update that merges the new 2.9 (master) branch.
It also has an updated configurator that creates links instead of copying files. So once you have run this to do a new config or upgrade an old config then you won't need to run it again to upgrade after you hav done a git pull.

Cheers, Phill.

I want to say Thanks Phill for all of your hard work.

I did have a harrowing day trying to install Plasmac,

I first updated the package and could not find the Plamac Axis and Gmoccapy under sims.

I reinstalled the package about 3 times then gave up, It was by chance that I checked under by-machine and found it.

Now that I have set the basics up on my computer I will set up my machine and hopefully be cutting some steel!

If something doesn't look like it should then check out the first post on this thread, I update it every (almost) time that I change things.
I know it is a pain with so many changes but they should taper off as we get closer to the end.

Cheers, Phill.

If it helps to spur you on, I cut a full sheet of parts today on my half sheet machine with plasmac. (I had to index the sheet twice) I am not running the latest version but the only issue I had was warpage exceeding the probe height on one pierce but I was able to recover by holding the sheet down until it finished probing.
