I guess I should have posted this in the bugtracker. Still I kinda hoped there would be any kind of progress, yet it's nearly three weeks now since I started this thread.
I mean it can't be so hard to keep the same fan speed during the print in fixed mode instead of inserting these 100% jumps all over the place.
Guess it would be optimistic to expect any comment on the weird 99.608% vs. 100% issue (fixed mode doesn't use 100% even if set to 100% and "real" 100% much louder than 99.608%).
It's going to be fixed, 20% is going to be 20% all the time (for example). 99.6 or 19.6% could be rounding issue
