#Hotend fan Keeps turning off after enabled in slicer and manually enabled.

as the title suggests, I've been having an issue where my exhaust fan stops after a bit, despite being enabled in my slicer. I can enable it manually in my printer (Ender 3 Pro), and it stays on for a bit, but soon turns back off. I have gone through two bowden tubes (short because I'm using a DDE adapter) and have ended up with the same result every time. The filament then gets clogged, destroys the tube (hence to replacement), and hurts my extruder motor.

It sounds like there may be issues with the cooling fan and potential extruder clogs causing problems with your extruder motor. Here are a few steps you can take to troubleshoot this issue:

  1. Check the connections of the cooling fan to ensure it's properly plugged in and the wiring is intact.
  2. Monitor the temperature of the hotend during printing to see if it's overheating, which could lead to clogs and issues with the extruder motor.
  3. Clean the nozzle and hotend to ensure there are no filament residues causing clogs.
  4. Make sure the cooling fan blades are not obstructed and are spinning freely.

If the issue persists, it may be worth reaching out to the manufacturer or a 3D printing community for further assistance.
