So good afternoon folks I have had to step back a couple of weeks from printing (vacation, bad heater in my hot end etc). All that is fixed..

I have printed of cloughs layer fan (and his auto leveling, and x carriage and hot end cooling etc) and its great.
However, when i run it, the print quality is noticeably worse (PLA).
I have 4 test prints .
1. 100% fan
2. 60% fan
3. 30% fan
4. 0% fan

the test cube 3 and 4 look a lot alike, because there isnt much air blowing at 30% i dont think.

The ones that are running more air, seem to be much lower quality.

None of them are as good as i had it printing before making the mods (perhaps i have a slight carriage bolt loose or something). but either way, there is a distinct difference in print quality.

from left to right 100 60 30 0




any idea why this would be?
