configtool Mapping more than 3 Heaters

gruen

Hi,
I have a Duet3 Mainboard 6HC. When I select Duet3 in the configtool, I cannot select out3 as a Heater only as a Fan.

In addition, it is not possible configure four heaters (1x Bed, 2x Nozzle, 1x Chamber).
What do I wrong?

@gruen Thanks for pointing this out. Yes, you should be able to use out3. I've asked @chrishamm to change this on the config tool. For the moment, you'll need to add it manually to your config.g using something like:

M308 S2 P"temp3" Y"thermistor" T100000 B4138 ; configure sensor 2 as thermistor on pin temp3
M950 H2 C"out3" T2                           ; create chamber heater output on out2 and map it to sensor 2
M143 H2 S120                                 ; set temperature limit for heater 2 to 120C
M307 H2 B1 S1.00                             ; enable bang-bang mode for the chamber heater and set PWM limit
M141 H2                                      ; map chamber to heater 2

Modify the thermistor parameters to match your setup.

Thank you.

After more than 2 weeks, the bug was still not fixed.

@gruen We'll get to it when we can. @chrishamm has been away for a few weeks, and is responsible for the config tool, but is also working on the Duet Software Framework. Bugs are tackled in the order of severity, and this particular one has a workaround.

Ultimately, the config tool is a place to start the customisation of your machine. It cannot do everything, particularly for complex machines that use bespoke parts. Understanding and learning how to edit the config.g and the gcodes is an important part of improving your machine.
