Duet Web Control 2.0.4 chamber temperature

andornot

Does the chamber temperature for Duet Web Control 2.0.4 works as i cannot get it to display, it did int the previous version?

I would update to 2.0.6 first. And then if you find that the issue still persists, then report it.

How do you add a bed chamber to Duet Web Control 2.0.4?

You configure it in RepRapFirmware, then DWC will display it. See M141 Hnnn parameter: https://duet3d.dozuki.com/Wiki/Gcode#Section_M141_Set_Chamber_Temperature_Fast

If you are using RRF3, don't forget to configure the heater first.

@chrishamm is RRF3 the firmware 3.0? If it is i have and just want to measure the chamber first before sorting out the heater end as i am still sorting out the control 240vac by pwm using one of the fan controls.

@chrishamm I am really struggling to understand the code i get the chamber temperature displaying on the web control, please can you help me, example code below:

; Bed
M308 S0 P"spi.cs4" Y"thermocouple-max31856"
M950 H0 C"bed_heat" T0
M143 H0 S180

; Hotend
M308 S1 P"spi.cs2" Y"rtd-max31865"
M950 H1 C"e0heat" T1
M143 H1 S450

; Chamber

M308 S3 P"spi.cs3" Y"thermocouple-max31856"
M950 F0 C"heater3"
M141 H3
;M950 H3 C"fan0" T3
;M307 H3 B0 S1.00
; set pwm to fan0 to switch phase angle controller
M143 H3 S150

chrishamm

Yes, RRF3 is firmware 3.0. It sounds like you want to use this

; Chamber
M308 S2 P"spi.cs3" Y"thermocouple-max31856"
M950 H2 C"exp.heater3" T2
M141 H2

That will configure sensor #2 with a MAX31856 thermocouple, create heater #2 on "heater3" and sensor #2, and map the first heated chamber to heater #2.

@chrishamm thanks for the code i changed it slightly to configure to sensor #3 as i am using a Duet 2 board as i assume sensor #2 is taken by the second extruder. By the way your Web control is really good, i used smoothie boards for years not a patch on the duet with all its features and software interfaces.

I have just ordered a duet 6HC and looking forward to interfacing it with the raspberry pi and designing my own screen.
