Hey All, 

I have successfully been running PlasmaC for around 18 months now without any problems. (isnt connected to internet so hasnt updated over this time either)

Yesterday I cut a sheet of 16mm steel for the first time.

Today my THC is not working image missing /media/kunena/emoticons/dizzy.png. I am using 'Auto' THC, as I always have and have not changed any material parameters. I am not sure if it was working whilst cutting the 16mm or not as the parts were only small and float swtich was not activated.

The 'THC Enabled' and 'THC Active' lights are not illuminated, however I am still able to read cut volts. The lights on my THCAD-10 are still illuminated.

Does anyone know if I could have burnt someting out whilst cutting the 16mm? is this just a coincidence? How can I go about troubleshooting/fixing this problem?

Any help is very much appreciated.

(before someone else says it, yes I do intend on trying out QtPlasmaC I just need to get the time to read up about it and make it happen. What computer would people suggest works best with this? As I have had nightmares with the ones I used to setup my existing configuration)

PlasmaC did have a separate THC enable in the material file, is it enabled for that material?

I am not familiar with the nightmares you had setting up your current config, if it was install related or hardware related or both. A friend of mine had freezing issues with a Gigabyte Brix with the J1900 processor, I even bought one (and sold it shortly thereafter) to try to work out what the issue was and never made it anywhere, just doesnt like linux I guess (in all seriousness there was an issue logged in intel's known issues list, but I cant recall what the exact issue was, rest assured they arent going to fix it :) ).

Otherwise, I am not sure what you are running currently, but if it runs PlasmaC it will likely run QtPlasmaC.

Anyways, I made this guide some time ago, it's like baking a cake (click by click, etc). Following the package install route should yield you a machine running MX Linux 19.4 a bit nicer of a user interface than the standard linuxcnc distro) based on Debian 10:

Be sure to back up your config/important files before you start!

Phill made a nice migration script to get your setup from PlasmaC to QtPlasmaC: linuxcnc.org/docs/devel/html/plasma/qtpl...tml#qt_modify-config

A lot has changed, and it may be worth re-creating your setup in pncconf.

All that said, I don't know what you use your table for, but if you are happy where you are at and it's working for you, staying put is also an option :)

Im not sure, unfortunately I dont l know all the different hardware combos, etc. but FWIW, I do most of my dev work inside a virtual machine running on an AMD FX8350, with no issue.
