Missing notification for stuck filament

Synopsis

When encountering a stuck filament issue, there's no PrusaConnect notification. The first alert is when the printer cools down due to inactivity.

 

General information:

PrusaLink type (Raspberry Pi Zero / Pi 3 / Pi 4)

MK4 built-in.

PrusaLink version

N/A, using built-in

Printer type

MK4 with MMU3

Printer UUID (you can find it in Printer detail page - address line)

84e8e2c2-f525-414d-aee2-b030df08e57e

Printer firmware version

6.2.6+8948

PrusaSlicer version (if applicable)

I believe this is not applicable, but 2.9.3.

Description of the bug, including steps to reproduce (if possible).

When there's a filament jam detected, the MK4 parks the printhead and waits for the user to confirm to unload/reload the filament. There is no notification generated by this step. If the printer is left unattended for a long time, heating will be disabled due to timeout, and there will be a notification when temperature drops below threshold - but that's the first notification. There is a notification generated *after* the filament reload before the print starts, but that's not necessary.

Steps to reproduce:

* Printer has issues with under-extrusion or other jamming

* Start a print

* Wait for the jam

 

Expected outcome:

* I receive an immediate notification to go to the printer and help with unjamming the filament

 

Actual outcome:

* I find out much later, after the printer has cooled down.
