RE: Crash Detected

 

Posted by: @m-zielinski

The reading from the strain gauge sensor is fluctuating. It doesn't matter if it's hot or cold. I'm waiting for a new one to arrive.

@Wojta, do you know which wire was bent or damaged too much?

How much fluctuation? I think a certain amount is "normal" but large spikes are a sign you might have issues. On my fully functional zero issues MK4S at any static reading there is about +-20 which seems to be acceptable. I think anything close to that should be fine.

RE: Crash Detected

Printer was assembled, new out of box. No visual damage on cable. Fluctuation was in thousands. Normaly +/-70 then it jumped to -4000(+) I thing that lowest number I saw was -6500.

I tried to pull wires but all seems to be secured. I dont know pinout of this cable so I didnt check for continuity/resistance. But I still have that cable.

RE: Crash Detected

I just upgraded my mk4s to CORE one and this was the first problem after startup.  Changing the code to add M104 0 fixed it….but wth…

do I bother opening a ticket and hours of frustration ?

RE:

The answer by @Raaz is correct.

The troubleshooting step for me, which identified the issue:

1. Start print
2. Select Tune
3. Turn off Nozzle Heating

Immediately after doing this, my first print completed.

Previously, I would encounter a screen that said: "Crash Detected": "A printer collision has been detected."
and then got stuck on a screen that said: "Crash Detected": "Unable to home the printer.  Do you want to try again?"  (below) "Try checking belt tension or debris on the axes".  - with the only button being "Retry" - no cancel button, and no Timeout.   So your bed and filament heater stays on indefinitely.  Isn't this a bug?
