Crash when creating an Octoprint hardware printer

[laptop-laptop]

Describe the bug

I am not sure if I did that incorrectly or it is a bug. For the past year on both SuperSlicer and PrusaSlicer, sometimes when I set up an Octoprint connection, the program exited by itself. For example, today I pressed the cogwheel icon under Printer Settings. I entered the name of the printer, octopi.local as the URL and the pasted the API from the web browser. Clicked the Test button and no error. SuperSlicer told me that the name of the printer already existed and asked if I would like to replace it. I clicked OK. Then, the program exited by itself. I had to launch the program again and re-enter the name, URL and API. Then, when through the same thing and the program exited for no reason again. Over the year, sometimes both programs exited when I pressed the Test button. I wonder if my way of setting up the Octoprint connection is wrong.

To Reproduce
See above

Desktop (please complete the following information):
Windows 10
SuperSlicer 2.3.56.9

If it exits without a bug message, it's a bug.
But it may be a bit difficult to reproduce...
If you launch it on a command prompt (win+R, cmd)
with the command [...]\superslicer_console.exe --loglevel=3 (drag&drop the superslicer_sonsole.exe into the command line and add the --loglevel 3), can you copy & paste the last lines of logs, after making it crash?

[laptop-laptop]

Yes, it exists without a bug message. Where is the logs located?

BTW, are we supposed to launch SuperSlicer by double clicking superslicer_console.exe or superslicer.exe? Usually I do the latter.

[supermerill]

Where is the logs located?

on the cmd window where you entered the command

thanks
I'll add a bunch of logs to try t pinôint the moment when it crash. I'll come back to you this week.

[laptop-laptop]

Thank you. Is there a limit on the number of times I execute "[...]\superslicer_console.exe --loglevel=3"?

As another test, I entered the printer name, url and API. Then, pressed the return key when the cursor was in the API entry box. Again it crashed.

I tried to get the logs but I can no longer use the command you listed to launch SuperSlicer. Windows keep telling me that the application cannot be executed on my PC.

[supermerill]

no limit, it's just a way to add --loglevel 3 as a parameter to the exe to enable logging. You can also use the level 5 to have even more logs.

[laptop-laptop]

Is there a guide on how to set up Octoprint with SuperSlicer? Maybe I did not do it properly and caused the crash.

[supermerill]

I just copy the ip of my raspberry pi and copy/paste the key from the octoprint interface. Nothign special

[laptop-laptop]

After copy and paste the IP or the API, are we supposed to hit the return key? I recall that one time after I pasted the API value and hit the return key, it crashed.

[supermerill]

The return key validates the value, but clicking on something else out of it does the same thing.
The current nightly have more logs, can you make it crash and send me the new log?

I'm seeing this same issue. Spent some time setting up everything for print settings etc. and after "Add physical printer" and Octoprint settings, SS crashes to the desktop. Since I hadn't saved the presets (my bad), all was lost upon restarting SS.

Upon further testing, I have found that if you set your bed size (and a texture in my case), before you "Add physical printer", it will crash every time. If you set your bed size afterwards, it works fine.

Windows 10
SS Version 2.3.56.9

can't make it crash.
What are the exact steps?

[SW0rden]

Open SS, go to Printer Settings tab, Bed Shape/Set, change the bed size and OK, Edit Physical Printer and set it up for Octoprint, hit OK.......crash to desktop.

If you Edit Physical Printer and set up for Octoprint first and then set the bed size, your fine.
