Thank you both for your quick replies. I have had a look at it and I think I had misunderstood how it works with regard to being active/off and then selecting temperatures to actually make it start to heat the hot end. I have played around with the config file and it works as you describe by commenting out the T0. I initially thought you were talking about in the heater definitions, but I found it at the end of the config file.
Thank you for your help
Hi all. First time using and setting up a duet board, so this will probably be user error! I'm using a Mini5+ on an AM8. I have used the config tool to make a config file and have uploaded to the duet following the setup guides, but heater 1 seems to default to on (on the UI at least). I have only powered by USB so far, so main power hasn't yet been applied to the board. I have heater 1 set up as the hot end heater, and its plugged into Temp 1 on the board itself. The heater is 2A so I have wired directly to the Duet without an external relay etc.
from config.g
; Heaters
M308 S0 P"temp0" Y"thermistor" T100000 B4725 C7.06e-8 ; configure sensor 0 as thermistor on pin temp0
M950 H0 C"out0" T0 ; create bed heater output on 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 S70 ; set temperature limit for heater 0 to 70C
M308 S1 P"temp1" Y"pt1000" ; configure sensor 1 as PT1000 on pin temp1
M950 H1 C"out1" T1 ; create nozzle heater output on out1 and map it to sensor 1
M307 H1 B0 S1.00 ; disable bang-bang mode for heater and set PWM limit
M143 H1 S230 ; set temperature limit for heater 1 to 230C
I have tried M950 H1 C"!out1" T1 ; create nozzle heater, but it has made no difference after a reboot etc.
I have had a look through the forum and documentation but can't find a fix.
Any help would be greatly appreciated, thank you
