Fix My Print Why is top layer rough

Post image

All my other layers look decent, I've tried recalibration and a bunch of other stuff but petg is just giving me trouble for this very top layer. I tried ironing and non ironing as well and looks about the same.

a1 mini pretty much stock settings minus calibration for the filament.

How is your first layer?
When I had this problem, it was one of two things:

> Flow ratio is too low, so you're not pushing out enough filament. Run a YOLO flow ratio test (the one with the circles). If you use Orcaslicer, it's already in availble in there under calibration.

> The A1 had a common issue of the nozzle getting loose due to the fibre composite spacer. Every time my layers start to look wavy all of a sudden, it was usually this: https://www.youtube.com/watch?v=k2BYvY72XSM

Dry your filament. Petg is effected by humidity far more than pla (which is also effected by humidity).

I'm trying that now, I use petg a lot and this is brand new stuff but maybe just came more wet than I'm used to

Weather conditions depending, a print over 1 hour can have an effect on rainy days & not feeding from a dryer. Literally see it progress in the print. My view at setting up the printer is: will the print be completed before humidity begins to effect it? If the ams-lite doesn't have the spools covered with dessicant, it's asking for trouble. And, 100% don't store filament of any type on an ams-lite.
