No error when uploading print to Printer Host when printer not connected

[RichiH]

Version

2.3.0 RC3, Linux

Operating system type + version

Debian unstable/testing

3D printer brand / version + firmware version (if known)

Prusa Mini+, 4.2.1
Octoprint 1.5.2

Behavior

• Disconnect Octoprint from Prusa Mini in software (e.g. to change filament), USB connection is fine
• Slice a model
• Click the "Send to printer"
• Enable "Start printing after upload"
• GCode transmits correctly, print does NOT start and NO warning is shown

I would expect an error/warning instead.

I don't know if this is an issue with Prusa Slicer, Octoprint, or both, but I have to start somewhere so I did it here :)

Do you get a "failed" message in the upload log? Go to menu Window -> Print Host Upload Queue. We should add a notification for "upload finished" / "upload failed". ne 10. 1. 2021 v 0:28 odesílatel Richard Hartmann <notifications@github.com> napsal:

I can check after the current print finishes. I would argue that "success" is optional and it would be enough to have one of those new-style overlay notifications in the lower right of the 3D view. For "error" I would strongly encourage a pop-up so it can't be missed when you're in a hurry.

I disconnected Octopi from my printer, sent a job, and:

Completed means transferred, not printed.

Arguably that should be renamed then.

Yet, the main bug is that PrusaSlicer does not inform the user that the print didn't, in fact, start.

Yet, the main bug is that PrusaSlicer does not inform the user that the

print didn't, in fact, start. I am not sure whether the OctoPrint API supports that, at least in the upload API. I suppose PrusaSlicer would have to invoke another API, possibly after a while. út 12. 1. 2021 v 20:26 odesílatel Richard Hartmann <notifications@github.com> napsal:

That's absolutely possible; I had to start somewhere, but I can create a sibling issue in Octoprint, link the two, and try to facilitate the conversation that way.
