manually tuning Heating rate
-
I have a toolboard and I would like to manually tune the heater.
I've read the wiki and the gcode reference but I couldn't find any reference on how to find the R parameter (heating rate). Is it a constant that is automatically found by the firmware?
Alternatively I'll route everything to the main duet3 and run an auto-tune, but I would really like to understand how it works. Thanks

@matt3o If you have the 3.2 firmware installed, you can now tune on the tool board. Use M303 T0 S250 or your preferred temp. Using T0, will use the part cooling fan as part of the tuning.

@Stephen6309 you sure? They said it was postponed to 3.3

You can still use the gain parameter A in the M307 command instead of the heating rate R. They are related by R = A/C where C is the cooling time constant.
