I have mentioned this in the 1.8.x feedback thread before, but decided to start a new thread dedicated to this issue (feature?).
So OK, we have learned that the 100% fan jumps in the auto fan profile are meant to improve pillowing.
I still think the implementation is rather weird, but what's really bothering is that this feature somewhat completely destroys the possibility to use a fixed fan speed.
For this test, I sliced EXTRUDER-COVER-V6-front.stl from the library (Z-ABS, 140µm, high quality, 20% support lite) with fan set to 20% (auto off).
The fan profile shows that the oscillation between 100% and 20% starts at 7.5mm and ends at 14.1mm ... but then it stays at 100%.
4064
Start of fan oscillation at 7.5mm:
4065
End of fan oscillation at 14.1mm (stays at 100%):
4066
I think we can agree that while there is a top surface at 8.85mm and another at 10.8mm and 14.25mm , there is certainly no top surface for the next 30mm or so.
So why does the fan stay at 100%?
And is this 100% thing really supposed to work in fixed fan mode at all?
So there is no way whatsoever to set the fan to a fixed value if Z-Suite decides otherwise???
In some other thread we came to the conclusion that 100% in fixed fan mode actually only creates 99.608% fan speed while the auto mode and this new "anti pillowing" mode create true 100%. Issue of rounding vs. truncation maybe?
While a 0.392% difference seems negligible, the audible difference seems to be considerable.
Anti pillowing you say. Printed this at 0.09. Had much support under the part. Infill was set to light. Would be good if you could set how many layers you have on top which leads me to ask why isn't there a top layer option; something to do with warping?
With each new Z-Suite release comes new bugs and less features in the software. Zortrax's backward approach to their so called updates just blows my mind. I am still running Mac Z-Suite v1.1.0 as I haven't the time nor energy for their software headaches!
I cannot help but think we are nothing more than Beta testers, leaving us to do all the hard work of finding, reporting and figuring out the bugs....
if you need I can make another graph and send the stl
I have just checked it by myself, it has to be a bug.

I bet thats the broken fan’s fault. Can you get me ZCODE? I’m gonna print it
Dont know how you managed to eliminate pillowing on your printer, perhaps different colors have slightly different properties?. As for that for the .stl i have done much of a redesign and printed the parts up right. I am extremely happy with the end product. please see pictures.

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%).
