Some profiles lag behind the firmware versions, which started to require certain minimum values, such as fan speed.

IL check on GitHub because this starts to be an issue because some presets are just old.

Thanks.

That reminds me, that those fan errors appeared after I changed filament to PM FRJet (Before, I was printing using Prusament only).

But I use the official PM FRJet filament profile delivered by Prusa. Indeed, it has a fan speed range of 5-15%, while Prusament PETG profile has 30-50%.

I had that fan issues with a Fiberology filament, the fix is to increase minimum fan speed in filament profile, see https://forum.prusa3d.com/forum/hardware-firmware-and-software-help/hotend-fan-not-spinning-check-it-for-possible-debris-then-inspect-the-wiring-error/#post-726328

I do not have the Mini, but my MK3 has been running fine with the fan check disabled for maybe three years or so. I just got tired of the (false) alarms/aborts that some glitch is causing.

Recently I encountered this error "print fan is not spinning" error twice. It caused immediate print interruption.

The error is displayed on the control panel. The Print Fan did not spin indeed. Attempts, with use of a finger, to make it work give no results.

But turning the printer off and on again, makes the fan spin again.

On the Internet, I found suggestions to disable fan check.

Is it a known issue? Does that mean that the fan deserves replacing? Or it's software problem?

Edit: I disabled Fan control and started the next print. After some while I found that the Print Fan is not spinning. In the control panel, in tuning section I found it's turned off.
