RRF Configurator & PT100 on Maestro

JRDM

My uSD card died so I thought I'd try the RRF configurator to speed up setup.

Heater 1 has a PT100 on it and I set up what I thought was the correct setup. RRFC spit out this line:

M305 P1 X200 R2200

It should have been:

M305 P1 X200

RRF seemed to get confused with the 'R2200' parameter. Once I removed 'R2200', the sensor worked fine.

For the moment everything else seems fine.

The 'R2200' parameter is required for a Maestro.
If it was another board like the Duet2 i think is R4700.

This is my Hotend heater line for a E3D V6
M305 P1 T100000 B4725 C7.060000e-8 R2200

And my Bed is
M305 P0 T98801 B4185 R2200

Looks like you are missing some parameters, possibly

Thanks for pointing this out, we'll get it fixed.

Actually the R parameter is almost never needed. The cases when it is needed are:

When using a Duet 085 or a later Duet 06 with a thermistor, because the default for these boards is 1000 but later boards use a 4700 ohm series resistor;
When using a PT100 with a third-party MAX31865 interface board, and the reference resistor on that board is not 400 ohms.
