Hey everyone,
when I am printing PLA with 220°C/45°C all works fine the prints run without any issues. But when I try to print ABS at 260°C/100°C it fails after about 10-15min with the message that the klipper lost the communication with the mcu. But that is all. I could get any solution from the logs. The thing is, another printer (Flsun SuperRacer) works without any issue at that temps.
Before printing I tuned the PIDs for the said temperatures. Can someone help me?
Greetings

This gets written to the journalctl, the thing is though, it doesn’t matter which cable I use. I used the cable of the SuperRacer to check if it is a cable issue. I even swapped the mainboard with a different one, same model though.

This could an issue with your power supply. The voltage might be dipping under the sustained load of running the bed at 100C.
I suspected it might be an issue with the power supply. I will try a lower bed temp.
It was the power supply, after lowering the bed temps it worked fine.
