Flash stock - Extruder not heating at expected rate
Hey guys, I need to flash the backup .hex of my stock firmware back to my MK3S+, I've been getting a heater not heating at expected rate error, and generally things have been very unpredictable and bizarre after switching from calibrating PLA to PETG. Is there an easy way to load this .hex back onto my board?

I see now I was thinking at a bit too low a level. I think there's a workflow from prusaslicer for it
Did you do PID tuning? And did you remember to save it to the config with SAVE_CONFIG? It needs to be done both for the extruder and the bed
Sounds like you might not have. If you did, a more powerful heater usually solves that problem, and it's a cheap and easy upgrade, if it's the hotend that's the problem. I know those mk3s come with a measly 30w heater iirc.

I did not. I'm very very new to this as you very well must be able to tell.
I'll hook everything back up and run some more tests.
I think I would like to upgrade though, is there a commonly recommended bigger wattage?

Maybe your fan is spinning too fast, causing the heating head to be cooled by the wind
Heater extruder not heating at expected rate
Transition to shutdown state: Heater extruder not heating at expected rate
See the 'verify_heater' section in config/example-extras.cfg
for the parameters that control this check.
50 is a good spot

Thanks all
I reseated my hotend thermistor and heater cables and it's progressing further than it used to
Yeah it completed and didn't throw any of the errors
yay 🙂
Klipper is rather picky about heaters and temperature, it's a safety thing
