Heater issue: Heater extruder not heating at expected rate
Hi. So, I been having this issue randomly for some time now and it's driving me crazy at this point.
My VCore has been working fine with the Rapido (not UHF) for some time now and I have been able to even print for 40 hours with no issues whatsoever. However, for the past three weeks I haven't been able to print not a single thing because of the verify_heater issue. I can see on the Mainsail graph that once the temperature I use for PETG is reached (245), it randomly ramps down between 20 to 40 degrees and most of the times is not able to catch up and start printing.
I have searched around here for this same issue and tried all the options I have found: Redoing PID calibration, changing for loose/broken cables (I even changed cables from another Rapido), changing the thermistor and even replacing the heating cartridge but nothing works, I will always end with this same issue at some point. Usually happens before starting a print, but it also happened mid print multiple times.
I have attached both klippy log and printer.cfg. I don't remember changing any config parameter that could break the printer, but at this point I don't know what I'm missing here
