BUG: XL Printer goes offline when extruder heat command is send

[ingbrzy]

Printer: Prusa XL 5 heads Firmware: 5.1.2

In the PRUSA Connect nozzle temperature is shown as 6°C when all heads are parked

When all heads are parked and I send command via PrusaConnect Control to preheat NOZZLE (any temp), printer goes instantly OFFLINE and error is shown on the screen

[ingbrzy]

one more point, when all heads are parked, nozzle position overlaps with text on Prusa Connect..

solved by 6.0.0 RC3 Firmware

oh nice, i missed this one, also that's not MK3 PrusaLink at all. Why is this repo plagued with connect and MK4 XL stuff aaa :D

[ingbrzy]

sorry, not fixed.. just tested again..

[ingbrzy]

where to report XL Prusa Connect issues?

[TojikCZ]

It's like multiple issues at once, one or two for XL firmware and some for connect. I cannot even move this issue to the appropriate repo since it's at least 3 in 1.

Again, this repo deals with the MK3 PrusaLink raspi thing,

Yes i'll go and split it myself :/ but please, use the connect feedback thing on the bottom right for connect issues and Prusa-Firmware-Buddy for FW ones

I think I've found another place where this issue pops up directly on the printer.

I'm using 6.0.0 RC3 on a 2 tool XL.

When heating a tool to 240, 250, or 230, (I'm sure it works at any temp above idle) via either, first, manually setting the tool temp or, preheating the system, or directly telling it to load a filament and then choosing a temperature, or going to > Move Axis > then setting the temp:

The printer will heat the tool correctly but after waiting, what appears to be the dwell time, the printer times out, crashes / resets, and then warns of a bad heater or temp sensor wire issue.

It seems to escape to the the watchdog somehow and never move past the safety checks in the preheat cycle.

The system will run cycles normally and not experience this issue but when attempting to manually interact with the tool's nozzle temp it leads, invariably, to an error.

This was tested on tool 1 if that makes a difference.

Possible related to this: #3888 ?

@ingbrzy @eltron247 can you test on 6.1.3 and confirm if this is still an issue?

Still an issue on latest non-alpha firmware. The temp starts going up and then a PrusaConnect error/Printer error occurs requiring a reset:
