QTPLASMAC integrated cad/cam

Good start!

Materials, there are two ways (at least). One is to set all options in Sheetcam and that overrides the settings from the Materials tab.
Sheetcam is then the master of everything. That's what you have seen.

An other way is to set material index from sheetcam, it uses then the material index from the Materials tab.
Still, you need to select that when you sit with Sheetcam.
For that you need to go in the post processor code and change to false line 24
useTool      = false  -- Set to true to use SheetCam's tool table to generate a temporary material file entry

An other way, that I use, is to set material myself when I am at the machine.
Sheetcam only makes the cutting movements, not the material selection.
For that, insert comments in the printouts on line 171 in the post processor
   else
      post.Text ('; M190 P' , tool,' (',string.lower(toolName), ' material)\n')            
      post.Text ('; M66 P3 L3 Q2 (wait for valid change)\n')         
   end
Note the initial ";" comment in the printout. Plus useTool=false.

Automatic nesting isn't needed, at least to start with.
Being able to read in several G-code objects and interactively
place them on a sheet would be golden.

I like your start and hope you continue.

I ran sheet cam for a long time on my mach 3 plasma table. Maybe I am a little confused with qtplasmac its my first time using it. I just dont understand why you would have a materials tab and then end up setting all your speeds and feeds in sheet cam? Is this only for the conversational? Either way all in one would be much better. I am trying to keep it super simple so that I can teach people super easy how to run my machine. There also is no automatic nesting in sheet cam and I know this is not a easy task but, for a basic version should not be to crazy. This is what I have done so far, all internal to qtplasmac

How good is Ethercat motion control?

Category: EtherCAT

This is just an interpretation from reading similar issues here(forum), not empirical experience.

But the pattern you describe (random errors on startup, weird state after homing, reboot fixing it, and then everything staying stable) really looks like something in the startup / state synchronization / handshake is sometimes not lining up cleanly.

It doesn’t sound like a continuous motion control problem, more like: sometimes the system and the drives don’t start in exactly the same state (mode, position reference, command bits, etc.), and once that initial state is “clean”, everything behaves fine.

Things like edge-triggered vs level-triggered command bits, timing of enable/mode changes, or initial position/mode sync could easily lead to this kind of “works most of the time, but not always at startup” behavior.

So my guess would be to look closely at the startup sequence and state/mode/position synchronization, rather than at EtherCAT performance or servo tuning itself.

On the probe page in qt designer, there is a button where the probe to is and the output from linuxcnc goes to the led on the probe graphic, use that as a template

First i hear about btop ... strange as i used htop a lot a while back!
htop should be in the repos, old and new.

@tcbmetalworks, focus on the features you like to have.
I'm sure it will spark some interest when you show us.

The OS is Welcome to Ubuntu 20.04.6 LTS (GNU/Linux 5.4.0-216-generic x86_64)

surprise
Let me check... I see. Quoting
www.thomas-krenn.com/en/wiki/BTOP_-_Moni...nux_system_resources

"btop is the successor to bashtop and bpytop and provides a modern, resource-efficient interface for monitoring system resources such as CPU, memory, network, and processes."

and

"On Debian 12 and Ubuntu 22.04 or newer, btop is already included in the standard repository."

So I guess that explains why you don't have btop available.

Maybe install btop, then you can watch a lot more stuff, including network and disk usage. When I learned of btop, I pretty much dropped using top because btop is sorta nice. sudo apt install btop

hope that helps

No manual entry for btop

Log in to SSH, start "top" and monitor CPU usage and see if "log" appears often near the top of the screen.
If high CPU usage and no logs = DDOS
If both = brute force = someone trying to find user passwords using automated software
-
We had no brute force for quite a while as the result of that was the influx of existing member accounts being hijacked and used to post spam.
Or also possible, users using stronger passwords so much harder to crack. This is highly likely as nowadays wherever you register there are several warnings to use stronger mixed passwords.
 

The CPU usage is back to normal right now.

It really seems to me like you are confusing what QtPlasmaC does and what the conversational inside of QtPlasmaC does.

QtPlasmaC does control the Z axis on its own, with exceptions being things like turning the THC on and off via g-code.

QtPlasmaC does not add lead-ins
QtPlasmaC does use the material feed rates


QtPlasmaC Conversational can add lead-ins if you so choose. It is also set up so that the material you have selected when creating the conversational file will be the material used for the generated g-code, thus using its feed rates.


QtPlasmaC is not a CAM package at all. Nor was its included conversational intended to be a replacement for a good plasma CAM package. It's there for convenience only.

This kindof makes a mess if you want to use sheet cam or something similar.

I suspect this view point to be a result of your inexperience with Plasma cutting. I create all of my cut jobs using g-code provided by SheetCAM. It's not a mess at all, and allows for great control of cutting.

aswell as theres not really a great way to run sheetcam via linux as far a i know.

Is the download link at the bottom of this link too convenient?
sheetcamshop.myshopify.com/pages/download-sheetcam

SheetCAM in Linux works fine.
