Prusa Mini - PID Tuning?

I've been looking for a while and am of the belief the Mini does not support PID tuning that can be saved to the EEPROM. I have checked the Calibration selection on the printer and nothing says PID. There is one selection that seems to support a test to make sure it's working, but nothing about PID tuning. Is this another of those things that has been locked out, due to concern about someone breaking the printer by using your own Marlin settings?

RE: Prusa Mini - PID Tuning?

simply add the M301 command with right values in the start gcode within the slicer or octoprint.

no way for the bed, autotune is enabled only for hotend

RE: Prusa Mini - PID Tuning?

This post is very high in Google's results, so here is all the info I needed to PID-tune my Mini. Run this stuff from Pronterface, record the results, and add the gcode at the top of Printer Settings->Start G-code. I have a few mods, so my PIDs are way off Prusa's, and may be worse than the default for your printer!

-Extruder-
M301; view current values
M303 E0 S230 C10; 10 cycles at 230C
M301 P17 I1.5 D47.5; my measured PIDs!!!

 -Bed-
M304; view current values
M303 E-2 S70 C10; 10 cycles at 70C
M304 P44 I3.6 D360; my measured PIDs!!!
