Filter fan on 3d45 not working

hi so i noticed that my filtration fan was not working when i print but when i go onto service tools and turn it on it works fine is this a problem or should i not be worried i did do a lot of back to back prints with no cooldown time in between could that be it and do i need a new fan

Hi RandomSAOfan,
It’s quite a time ago since your post. But because I have right now the same issue with the exhaust fan on my Dremel 3D45 I would like to ask you if you find a solition for this problem.

There are no hardware issues, you can check the M106 command. If there are multiple fans, you still need to use the P parameter to specify the fans. My friend encountered a similar problem when using PETG to print Sonic the Hedgehog for his son before
