seeing if i can get assistance with bed connectins
-
i have a 24 volt bed i am trying to hook up. i have a duet3 6hc i ran the bed to out1 and ran 24 volts to the out1 in. curious if that is wrong or my config is wrong. also is there a pos and neg on a bed.
-
@frnknstn i am also trying to figure out how you guys show your config on here. I appreciate the help

@frnknstn as of right now i get a fault for the bed not heating up. Sorry im new at this and i am really trying to learn this stuff. I am also trying to figure out the tool show bed and bed heater. Where would i change my settings to add the nozzle to that. or do i even need them in the tools. thank you
-
@frnknstn The bed heater mat doesn't have polarity. It's just a big resistor.
The fault you're getting. Is it the normal one where it's not heating up fast enough? If so, you just have to do a pid calibrate for the bed heater: https://duet3d.dozuki.com/Wiki/Tuning_the_heater_temperature_control
-
@gixxerfast yes sir. it says its taking to long. Heating up at .02.
ill look into this thank you -
@frnknstn i had to stop the tunes. My fans are not coming on
-
@frnknstn, do you know the power specifications (in watts or amps) of your bed heater and 24V power supply? You need to make sure the power supply can provide power to the bed, motors, nozzle, fans, electronics, etc.
-
Your config shows bed on OUT0 and extruder on OUT1
; Heaters M950 H0 C"out0" T0 ; create bed heater output on out0 and map it to sensor 0 M950 H1 C"out1" T1 ; create nozzle heater output on out1 and map it to sensor 1But you say:
i ran the bed to out1 and ran 24 volts to the out1 inCan you describe your connections using the names in the Duet3 wiring diagram image here so we know what you mean by out1 in?
Maybe also post an image of the board and wiring so we can see the jumper settings.

@frnknstn so i have my heat straightened out almost.. i started tuning but i cant get the fans to go. ill send a pic of my board

@alankilian i will see. the bed heats up and the extruder heats up. i will see what happens

image url)I changed it and it actually seperated the bed and extruder into 2 seperate tools
-
@frnknstn now im just trying to get these fans going
-
Looks pretty much like mine:
-
@alankilian i still have to do z probe and fans. then bed leveling. paused on probe was getting frustrated. So i have been messing with heaters. Now im trying to figure out fans on extruder and parts cooler
-
@frnknstn so on my extruder fan, should i just run that always on by the power strip, i am running 24v fans throughout
-
@frnknstn Not all 24V fans can be PWM:ed Do you have more than two wire fans? Can you show how you connected them ?
Have you set the jumper to V_fused for 24V ?
