FAN speed not working

Snapmaker 2.0
1

Hello together
I have noticed that the fan does not work properly. When printing it sounds like there is only 0% and 10% fan speed.
If I try with M106 S100 or M106 S255 it always sounds the same.
I have two print modules and both have the same behavior.
The SM2 has the latest firmware installed.

That is by design. The range is 0% to 100%. Anything above 100 will just be 100%.

There was a change in firmware a while ago which means the S was scaled to 0-100 instead of 0-255.
