M106 - Feature Request, Limit MAX PWM parameter

[gen2eng]

It would be nice to have a M106 parameter similar to L that would limit the maximum PWM value for a fan.

Usage:

• I was brain dead and discovered 2 hours into a 12 hour print that I really don't want to run my fan as hard as it is to minimize heat rise in the motor. A quick command in the console saves the day to cap the maximum value.
• Fan needs to be limited in an office environment with several newbies who are learning. Once again, brushed layer fan only wants to be run at 80% for extended period to times to reduce heat.

You can define the layer fan speeds in the slicer. Isn't that sufficient?

[gen2eng]

Yes, and limiting the max PWM is to mistake proof and protect against damage.

It would be more applicable to brushed motors than brushless motors

I have added this to the firmware wish list, however it will be low priority unless more users want it.

@dc42 Thank you!

@dc42 So here is another user (me) M106 Maximum Fan Speed Setting - that just missed this thread.
