Connecting the heaters
-
Is it a problem if I connect the heaters for the toolheads to out1 - out4 on the MB6HC3

@crazycreator I don't believe out4 is designed to run heaters directly and are mainly aimed at fans etc, I think you would struggle with the current needed, if you need another heater it will be safer to use an expansion board like a tool board.
-
Can i also use out0 as an output for the HotEnd-Heater, or is it only intended for the bed heater?
-
@crazycreator you can use out0

hi @jay_s_uk
That's what I originally thought too...
But nothing happens on out0 (these are the screwable connections, right?). The multimeter shows 0 volts.This is what the config looks like:
; Bed M308 S0 P"1.temp0" Y"thermistor" T100000 B4138 A"Heizbett" ; configure sensor 0 as thermistor on pin 1.temp0 M950 H0 C"1.out0" T0 ; create bed heater output on 1.out0 and map it to sensor 0 M307 H0 B0 S1.00 ; disable bang-bang mode for the bed heater and set PWM limit M140 H0 ; map heated bed to heater 0 M143 H0 S140 ; set temperature limit for heater 0 to 140C ; Tools ; Nozzle Heater Config ; Tool 0 M308 S1 P"temp0" Y"thermistor" T100000 B4725 C7.06e-8 ; configure sensor 1 as thermistor on pin temp0 M950 H1 C"out0" T1 ; create nozzle heater output on out0 and map it to sensor 1 M307 H1 B0 S1.00 ; disable bang-bang mode for heater and set PWM limit M143 H1 S280 ; set temperature limit for heater 1 to 280C ; Tool 1 M308 S2 P"temp1" Y"thermistor" T100000 B4725 C7.06e-8 ; configure sensor 2 as thermistor on pin temp1 M950 H2 C"out1" T2 ; create nozzle heater output on out1 and map it to sensor 2 M307 H2 B0 S1.00 ; disable bang-bang mode for heater and set PWM limit M143 H2 S280 ; set temperature limit for heater 2 to 280C ; Tool 2 M308 S3 P"temp2" Y"thermistor" T100000 B4725 C7.06e-8 ; configure sensor 3 as thermistor on pin temp2 M950 H3 C"out2" T3 ; create nozzle heater output on out2 and map it to sensor 3 M307 H3 B0 S1.00 ; disable bang-bang mode for heater and set PWM limit M143 H3 S280 ; set temperature limit for heater 3 to 280C ; Tool 3 M308 S4 P"temp3" Y"thermistor" T100000 B4725 C7.06e-8 ; configure sensor 4 as thermistor on pin temp3 M950 H4 C"out3" T4 ; create nozzle heater output on out3 and map it to sensor 4 M307 H4 B0 S1.00 ; disable bang-bang mode for heater and set PWM limit M143 H4 S280 ; set temperature limit for heater 4 to 280C

Out0 will only output VIN if you have connected VIN to the OUT_0_input terminals.
See the wiring diagram for the Duet 3 and study the terminal block.

Ahhhh... thanks for the tip...
I can just do it like in my quick drawing:
-
Yes a short jumper is fine.
-
then I'll try that
-
as soon as you do it right, it works
