I have also connected and heated up a new heating bed as a test and I get the same message.
Have you done a PID tune for the bed heater?
not knowing if this a DC or AC bed - if it is a AC bed, it looks like you haven't wired it correctly to the SSR
I dont have a SSR ist a V Minion with the Skrat Board
then as Vitamin G said, have you PID tuned the bed heater? Is the bed heating at all?
The Bed is not heating anymore
check that you have continuity on the bed wires. You might have blown the thermal fuse
The new Bed to? I mean i printed 100h before without any problems...
@blacksmithforlife 🇺🇸 found the Problem
Can I cut out the defective piece and re-solder it?
I removed the defective piece and connected both ends with a wago.
Was able to print for 32 hours.
But now I get the same message. And the LED for the heating bed is not lit.
Could it be the fuse
The left one is Slightly browner on the outside like the right fuse
take the fuse out and use a multimeter to confirm it is working correctly
I removed the fuse and measured the resistance at 0.0 and also checked the continuity and heard the beeping.
I'm getting desperate with the printer...
what MCU do you have? SKRAT?
Yes
It doesn't matter which cable from the heating bed is connected to HB + or -, does it?
nope, bed is one big resister
What other options do I have?
Measure the heating bed again?
do you have the klipper.log file from your last print that had the issue? If so, can you upload it here
Yes here
looks like it didn't heat at all. So I would continue checking wiring, thermal fuse, etc
Ok Thank you, im gonna check it at the Weekend in my free time
