@dc42 have you downloaded the files?

Sorry, I've no time to look into it this week - I'm working on a very tight deadline for Duet 3. I expect to have time next Tuesday/Wednesday.

Is it possible to have an example of the parameter m308 connected to the pt100 sensor board?

M308 S1 Y"rtdmax31865" P"spi.cs1"

Marco Bona

Perfect, work with Y"rtd-max31865".
Thanks

I had a question about RRF3 on a Duet 3 Pre-Release 0.6 board. Is there an inbuilt fan behavior like the Duet 2. For example, Fan1 was "kind of specified" as the heatsink fan and was configured to power on the fan when the Duet was powered up just in case the temperature was above the set theromstatic threshold. Then when config.g kicked in it would actually begin checking if it were at the threshold or not and decide what to do with the fan.

No. https://duet3d.dozuki.com/Wiki/RepRapFirmware_3_overview#Section_Default_pin_assignments

Gotcha, so it could be plugged in anywhere on out4-out9, be defined as fan1 using M950. M106 can be used somewhere after that M950 to set that fan to thermostatic? The feature to turn that fan on full at power on I'm guessing isn't possible or needed because the fan won't be defined until config.g is loaded as well as config loads so quick that it doesn't matter if that fan is on at power up cause it's only a fraction of a second that it might not be.

@blt3dp Sort of. But because nothing is defined by default, then before you can use a fan in thermostatic mode, you first have to define a sensor, then a heater that you can associate the fan with.

So starting with the sensor and assuming that you have already defined S0 to be the bed sensor, and if you want to replicate the behaviour of Duet 2, you would probably elect to use S2 as the hot end sensor. So you would have something like:

M308 S1 A"Hot End Temp" P0.temp1" Y"thermistor" Tnnn Bnnn C etc....

Then you define the heater so something like:

M950 H1 C"0.out1" T1 .

You might find that a little confusing because in M308 the sensor is referred to by the "S" parameter but in M950 the sensor is referred to be the "T" parameter.

Then for you fan you'd have something like

M950 F1 C"0.out6"
followed by something like:

M106 P1 S255 H1 T60 C "Hot End Fan". (where T is the value that you want the fan to turn on at). Here "P" is the fan number ad "H" is the heater number.

Substitute your own pin numbers in the above.

Thanks for clarifying, I was going off the assumption that I had already defined sensors and heaters.
