Connecting Silicon Heaters

@ertence On the duet3 6hc. Where the OUT0 in connected to the SSR, that is the only thing you want in those two screw terminals. DO NOT put 24v into there, that is powering the SSR from start-up.

@ertence I'll be honest I don't like your wiring. Please buy some suitable wire and connectors.

Rushmere3D

@ertence Also your config.g doesn't seem correct, your bed needs to have Out0 as it's pin.

How many beds do you?

Rushmere3D

@ertence

This should be the config for a bed on OUT0, notice the thermistor locations and both are being controlled from OUT0 (How you have the SSR connected)

; Heaters
M308 S0 P"temp0" Y"thermistor" T100000 B4138 ; configure sensor 0 as thermistor on pin temp0
M950 H0 C"out0" T0 Q10                       ; create heater output on out0 and map it to sensor 0                           ; disable bang-bang mode for heater  and set PWM limit 
M143 H0 S70                                 ; set temperature limit for heater 0 to 70C
M140 H0

M308 S1 P"temp1" Y"thermistor" T100000 B4138 ; configure sensor 1 as thermistor on pin temp1
M950 H1 C"out0" T1 Q10                       ; create heater output on out1 and map it to sensor 1                           ; disable bang-bang mode for the bed heater and set PWM limit 
M143 H1 S70                                 ; set temperature limit for heater 1 to 70C  
M140 H1

How is the SSR going to be controlled if there is no signal being fed to the control inputs.

Without some source of positive voltage to the OUT 0 POWER IN V_OUT0 terminal there will be nothing appearing on the OUT 0 V_OUT0 terminal.

@fcwilt look at his picture and I didn't say not to power the OUT0 input.

I cannot make out what is actually there. Based on the "color blobs" the SSR was being fed from OUT 0.

@fcwilt What about other picture where they have daisy chained the power in all the screw terminals.

Well let's hope they didn't actually do that. It reflects a very poor understanding of what each set of terminals do.

Well it would explain why the heater is always on by default.

Hello again thanks for the answers while I was waiting for the answers I realized the problem was from the config then I see the replies I disconnected the 24v from out0. also changed the bed output from out0 to out2. everything is working well right now sorry for the messy wiring and bad "color blob" wiring diagram. it was my first project

Thanks to everyone.
