FAN control
-
Hi,
Im having trouble with the setup of my fans on WiFi 2 board.
I have a Chimera + hot end, with 2 parts cooling fans wired in parallel, as Cura doesnt allow individual contorl and it made my wiriing abit simpler.
I have the parts cooling fans connected to FAN0 output and Hotend fan to FAN1
I would like the below to work
- If H1 or H2 are above 50c, turn on FAN1. (currently working)
- Cura to control the parts cooling fans via gcode.
- Able to control the fans via the DWC (currently the sliders for TOOL FAN and FAN0 are linked together and they dont stay at the value selected. They will revert to 0)

@nedmo said in FAN control:

Cura to control the parts cooling fans via gcode.
Able to control the fans via the DWC (currently the sliders for TOOL FAN and FAN0 are linked together and they dont stay at the value selected. They will revert to 0)1 and 2 should work as you have it configured now, does it not?
For 3, TOOL FAN and FAN0 slider are the same thing. Tool fan will control the part cooling fan of the currently selected tool, and both your tools use the same fan, Fan0.
The slider will work to adjust the fan speed, but during a print that has fan control commands it will constantly change when commanded to by the gcode file you are printing. Is that what you're seeing?
-
So when I slice a file, the gcode is controlling the hot end fan and part cooling fan is free to be adjusted by DWC slider.
-
The hotend fan will be controlled by the temperature of the heaters you've assigned.
The part cooling fan will be controlled by Cura. The slider will work to change the part cooling fan speed temporarily, but during a print it will go back to whatever speed cura has it set to the next time it changes in the gcode file.
In DWC there is a little Pin icon/button next to the slider that lets you lock the fan slider in place, but it only functions while dwc is open in the browser.
-
slicer is definitely controlling the hot end fan. Its speed increases at exactly layer 3 as per my settings. Part cooling fan remains off until its manually turned on by slider in DWC
-
Please show your sliced gcode file so we can see what the slicer is sending for fan control commands.
Are you sure you're got Fan0 and Fan1 connected the way you are describing?
Your config should be correct, but I can't see the wiring or the slicer commands.
-
Yep have confirmed that hot end fan is connected to FAN1 and part cooling is on FAN0
Here is gcode from slicer OFFROAD.gcode
-
Check your slicer for fan settings. If it's Cura, check the printer profile. It looks like you have it set to command Fan1.
