I have had my Creality CR10S-Pro about 2 tas by now. It has functioned well. Some filament jams only. I still consider myself a beginner though J
After a jam a couple of weeks ago I noticed that the fan pointing at the nozzle (fan2, placed on the right sid) wasn’t running.
I bought a new fan, tested it was working before installing it to the machine. When starting the machine I found that the new fan didn’t run. Fan #1 was running)
I checked the wiring , which seems to be ok.
Since there are separate cables to fan1 and fan2, are they not supposed to ran at different times?
I would be greatful for any help and /or tips how to solve this problem..
@bobenten Fan #2 that at the right side of the nozzle is controllable, you can adjust its speed in the screen menu. Please check if the value is 0 at the fan speed setting. If this cooling fan did not work, the filament will melt in the tube and cause filament jam.
If you replaced a new fan but the did not work on the printer, it probably a mainboard issue. The pin port for the control fan got something wrong.
But there is another fan port on the mainboard, please try that one.
