Bed leveling problems at higher temperatures?

Hey, after printing several things from PETG and PLA, I wanted to print something from ABS, since my ABS roll is totally packed, I had to attach it to the external spool holder. So I sliced the file in OrcaSlicer, started the print job with bed leveling and flow calibration, and it started its normal process.

But when it got to the bed leveling, it immediately gave me 3 error messages, all from the Z axis force sensors 1-3, that something was jammed, or the nozzle tip was dirty and it couldn’t do the leveling.

After trying several times to move the bed by hand and check for dirt, where I could not find anything, I gave up and tried to start a PLA print, everything works without any problems.

My guess is that the bed is so bent at 90° that it has problems moving it, although I was able to move it up and down to 90° manually without a single error message.

Maybe someone of you had the same problem before.

Did you ever just try the print again? Or did it fail, you manually poked at it, and then because you didn’t get an error you switched to PLA?

Start the PLA print with the bed temp set to 90ºC and see if it also fails like the ABS did.

It’s a bit stupidly worded. Yes, I tried to restart the print several times, but the same error message kept coming up, and then I tried PLA.

I will try to start the PLA print at 90° and see what happens.

Did you ever tram the bed? This is absolutely not suggesting that you should, I’m just asking if you did.

No I didnt, but I read about it tho.

OK, good. If the error was something like “abnormal/spurious force sensor detection” what I would do is mark all of the knob positions and loosen them exactly 1 turn (or 1/2 a turn if you can keep track of the position accurately).

Or you could just do the whole tramming process, it will end up with them looser (usually too loose).
