Hi, i need to buy a prebuilt printer (some assembly is ok, but it is for work, so hours long assemblies will probably get it rejected). I’d like to have DWC as the web interface, i really like it much more than klipper, but i cant find any printer that used Duet boards as stock, is there any?

@o_lampe Hi, thanks for the help. I just discovered that the problem was, of course PEBKAC. I was turning on the chamber heater but due to frustration i wasnt setting any temperature to reach.... yeah. Thanks for the help tho

I would like to setup a chamber heater on my duet 2 wifi. I tried vert hard but i cant figure out how to do. I want to use the exp.heater3 pin on the expansion port.

i tried doing this:

M950 P3 C"exp.8"
while true
    M42 P3 S1
    G4 P500
    M42 P3 S0
    G4 P500

and with a multimeter i can see the pin changing from 0 to 3.3v. so all good. I then tried declaring the pin as an heater:

M308 S3 P"e1temp" Y"thermistor" A"Chamber" T100000 B4138
;configure sensor 2 as thermistor on pin e1temp

M950 H3 C"exp.8" T3
;create chamber heater output on e1heat and map it to sensor 3

M307 H3 B0 S1.00
;disable bang-bang mode for the chamber heater and set PWM limit

M141 H3
;map chamber to heater 3

M143 H3 S60
;set temperature limit for heater 2 to 60C

and if i click on “chamber” on the gui the pin is only at 0v. Chamber active is 0v, chamber OFF is 0v.

i also tried:

M950 H3 C"exp.heater3" T3

same result. Does someone know how to do that? thanks
