Idex fans wont shut up . Part Fan and Toolhead Fan on full

What is up with the fans? Just got my Idex v-cove 4 500 up and running and the fans are so loud and stay at 100%. Why are the tool head fans even going by defaults when the heaters aren’t even on?

I am using the default fans that came with the system. The only thing I did differently from the walkthrough guide is follow the instructions on os.ratrig.com/docs/guides/4028. because someone commented that this was assumed setup with rat os v2.1.

so i have T0 pwm plugged into what bigtreetech shows as J50 - and which appears to be mapped to PA8 which has given me control of T0 part fan. but i didn’t know what to do with T1 pwm part fan. so i plugged into J51 - but dont know how to enable/use that pin in the config file.

should i just take both pwms and punch them down to their respective tool boards?

even if i do that and it works, how can i shut those damn toolhead fans off. they are so freakin loud i can’t even think about doing the configuration cause i have no control over them. going crazy! #fans #toolhead

Solution

Connect them down to the toolboards. Set it up correctly and they'll quiet down. It may be loud while you troubleshoot. The guide should help you find the right pin names; it doesn't sound like you are doing a strange setup. Without the pwm pins connected and getting a proper signal they will run at 100%
