Add

[extruder]
pid_Kp: 23.862
pid_Ki: 1.020
pid_Kd: 139.595

then run PID_CALIBRATE HEATER=extruder TARGET=170 .Klipper recently made this a bit of chicken and the egg problem.

I ran the calibration on the heat_bed as well and stored the results in the main printer.cfg file. I noticed there are no other heat_bed settings anywhere else in the config. Is that expected?

[dz0ny]

Yes, as they are pulled as components from https://github.com/dz0ny/klipper-prusa-mk3s/blob/main/mk3s/einsy-rambo.cfg. so basically whatever you put in printer.cfg and is defined elsewhere you override the config.
