The root cause of the problem reported here is overloading of the Klipper host process. One can see this from a system graph of the log: [sys] In effect, the Klipper host process couldn’t process all the work it needed to do in sufficient time. This resulted in extended duration between heater …

[image] woodencliff: I have done PID tuning with 100% fan at 15C room temp. I do not understand what you mean with 15°C. You need to calibrate PID at your relevant target temperature, e.g. PID_CALIBRATE HEATER=extruder TARGET=265

[image] Sineos: I do not understand what you mean with 15°C. PID tuned with cool chamber. I upgraded heating cartridge to 80w, recalibrated PID, reprint, and failed again. klippy (10).zip (1.9 MB) The temp drop is filament change. printer.cfg (14.4 KB)

Sorry, no further idea. The recorded temps do not warrant this error IMO: [grafik] The big drop at the end is the error

[image] Sineos: The big drop at the end is the error From the log, the temp drop is after the error. What a doom. :scream:

Unfortunately not, since this would be too easy :wink: Your last recorded temperature is 270.5°C. The drop in the graph is an artifact due to the crash.

[image] EddyMI3D: Have you checked the PSU? You mean PSU overheat?

What ever. You read the thread? At last the solution?

@EddyMI3D I don’t think this is the cause. The hotend is quite good on target temperature and this is exactly what’s puzzling me: [grafik] These are the last recorded values before the error.

@woodencliff can you try to reproduce the error and immediately after it issue the M112 command? This will output additional debug information. Maybe it is good for nothing, maybe it helps. Absolutely possible that I’m dramatically missing something obvious, but currently I’m dumbfounded.
