@gloomyandy i tried your suggested steps and here is the result :
Boot duet and sbc
Turn on heater from dwc panel
The fan don't turn on
I turn off the heater
wait for the temperature to go under 70°C
hit emergency stop
turn on heater
fan don't turn on
emergency stop (heater hot)
fan turn on
wait for the temperature to go under 70°C
fan turn off
Turn heater on
Fan don't turn on

Hello, I have a strange behaviour with a fan that I set to thermostatic on my Duet3 6CH with SBC.
If I start the Duet or do an emergency stop with the heater cold (<70°C) the extruder fan will never turn on when the temperature get hot. Either if I start a print or I set a temperature manually.
If I emergency stop with the tool hot, the fan will then turn on and will function properly until the next cycle.
I'm a bit lost and don't know if this is a bug or I made a mistake in my config.

I did power measurement and you are right about this, the power consumption reduced when regulating the temperature so it's an acceptable value. Thanks !
Hello, I have a printer with 5 axis.
A and C are inter-dependant as if I move A axis only C will also move. I need to move C in the opposite direction to only move A. Kind of like a CoreXY structure.
I would like to be able to use the quick move buttons easily, if I go A+10 only A axis really move (so C need to move accordingly).
Is it possible to configure the Duet 6CH with latest RRF this way ? I have the same reduction factor so the other motor need to spin the same way but in the opposite direction.
Hello, I'm building a printer with a heated enclosure. I want it to be at 150°C in 30mn maximum. Currently I have 2x 750W heating resistors and it's not fast enough. I want to add one more but I can't keep them all connected during the print because of the power consumption.
My idea is to have them separeted in 2 circuits (one with 1x 750W and the others with the other two) with 2 SSR. So I use the 3 of them at the begining and when I'm at the temperature set I disconnect one of the circuit and keep only one resistor to make sure I stay at the correct temp.
I don't know how I can do that with the Duet config as I don't want to have to do it manually.
My current config is this one, I use a Duet3 6CH :
; H1 Chamber
M308 S1 P"0.temp1" Y"thermistor" A"Chamber" T100000 B4725 C7.06e-8 ; configure sensor 1 as thermistor on pin temp1
M950 H1 C"0.out1" T1 Q10 ; create chamber heater output on out1 and map it to sensor 1
M307 H1 B0 R0.092 C2302.8 D104.47 S1.00 V24.3 ; PID parameters
M141 H1 ; map chamber to heater 1
M143 H1 S200 ; set temperature limit for heater 1 to 200C
Could you please guide me in the right direction ?
@dc42 this is the problem, thank you. I will try to repair it
Hello, the thermistor of the heated bed give me really strange values. I don't put the heater on and it goes from 200°C to 450°C and it vary a lot.
I checked the resistance with a multimeter and it's around 98k at 25°C ambiant temperature. It's connected to "TEMP 0" input on my Duet 3 Standalone. I don't think the problem is the wiring as if I'm correct the thermistor is not polarized.
Here's the config for this part :
; HEATERS
; H0 Bed
M308 S0 P"0.temp0" Y"thermistor" A"Bed" T100000 B4138 C0 ; configure sensor 0 as thermistor on pin temp0
M950 H0 C"0.out0" T0 ; create bed heater output on out0 and map it to sensor 0
M307 H0 B1 S1.00 ; enable bang-bang mode for the bed heater and set PWM limit
M140 H0 ; map heated bed to heater 0
M143 H0 S120 ; set temperature limit for heater 0 to 120C
It seems correct to me but maybe I'm wrong.

M84 S30 ; Set idle timeout
I can rotate the system when powered down. I will look into 1.8 deg motors.
I put the correct steps per mm in my config.g (1275) and I can only have really slow speed (max 700 mm/mn, 12 mm/s). I don't really understand why I can't go further. This is a really low speed.
I tried calculating with EMF Calculator, you can find my calculation here. I understand I may not be able to go to 150mm/s but 40-50mm/s should be doable. What am I missing here ?
