Homemade, cheap, plasma CNC

I would not rush into QTplasmac until the dust settles after the move to Python3. I think have QTplasmac sorted but I'm not in love with it. It is very sluggish on my hardware

Perhaps it's not in love with you either...

I've not heard anyone else refer to it as "sluggish". Runs fine on everything I have it on, including the Virtual Machines I have set up. All on Python3 and cover Mint, Buster, and MX Linux.

I'd posit that there's an issue with your recently installed OS/dependencies that is to blame, and not QtPlasmaC.

Yeh dunno. It seems OK on my Chromebook running a Sim. The chromebook is not PREEMPT_RT. On the table I'm running on a Celeron J1900 with 4Gb (similar to the brix  Phil mentioned). Latency is better than my old J1900 Brix. I'm running Mint 19.3. I've done so much installing recently but I don't think the current environment is broken. I tried hard to do a deb install on MX Linux and Mint and just could not get either working so I am running a RIP install using your list of dependencies. Thats OK as RIP is all I have ever used in the past.

Upgrading to the latest Python3 version of V2.9 on my chromebook took me back to a dependency nightmare as quite a number of new dependencies were required even to open Axis. A lot weren't caught in the build process.  I don't think James needs that pain right now

But on the table QT seems like its running in treacle. You can't use the GUI buttons to stop the machine as they are not responsive enough which is my real concern so I reach for a hardware estop. There seems to be plenty of RAM when I run top.

I'm quite plasma time poor right now. My sales have gone through the roof, my supply chain is broken due to covid and I'm making parts I've never made for years becasue of shipping delays. I've even thought of buying a CNC lathe but I really need an 80mm spindle just to machine plastic so its not an entry level machine.

I'll have another look when I get time.
 

I think I went with xfce this time. I can never remember seeing any difference between desktops.

I might give MX another run. Its coming back to me now though. I was getting flaky WiFi with it...

Hold off for a bit, I may have installed standard 19.3 today from an existing download, my memory is so bad I can't remember.

Tommy has mint 19.3 covered and its not any harder than MX Linux.
The latest Python 3 upgrade has added heaps more dependencies and I think a lot are to do with QT.

Based on what Tommy shared, I might go looking for some more RAM once we get out of lockdown...
