Duet 3 - FW 3.0.1b - bed config issues

mkudzia

Hello,

i'm setting up duet 3 for my e3d tool changer.
I have already ported the firmware settings to the Duet 2 and they worked fine.

Now I have installed the duet 3 + 3ch extension card and setting it up and all seems fine EXCEPT

I got issues with the bed. Bed is 240VAC connected via SSR (setup works and worked on Duet 2 and Duet 2 with RR3 firmware)

Bed is connected via the Out0 and config is :

; Heaters
M308 S0 P"0.temp0" Y"thermistor" T100000 B4138 C0 		; Set thermistor 
M950 H0 C"out0" T0							        	; Bed heater
M143 H0 S225 											; Set temperature limit for heater 0 to 225C
M140 H0													; Map the heater to the bed

When I turn the tempreature on the bed - nothing happens, and on the board LED for out0 doesn't light up.
Also I tried the pin name "bed_heat" and "bedheat" and got message that the pins are undefined.

Issue with firmware or is the board faulty?

Have you provided power to the bed +VIN terminal as well as the main +VIN terminal? Duet 3 has separate VIN terminals for the bed heater.
