Tuning Mini Bed PID
Hi,
I've been using Octoprint to tune the PID settings on all my printers, but I'm unable to do so with the Mini. I'm using the following command:
M303 E-1 S100 C10
For most printers that would run the PID tuning program at 100ºC with 10 cycles. The Mini responds with:
Recv: PID Autotune failed! Temperature too high
I've tried temperatures down to 50ºC with the same results. Can anyone replicate this or tell me what I'm doing wrong? Is this a firmware limitation or a bug? Extruder PID tuning works fine. Firmware version 4.3.1
Thanks!

I do not think PID Calibration is an option on the Mini.

It's possible using an octoprint host.
M303 E0 will successfully tune the extruder
M303 E-1 returns a temperature error. Any value of S is considered outside of machine range, from 30ºC up to 100ºC
RE: Tuning Mini Bed PID
It looks like you need to use "M303 E-2".
