I don't think that's it since S3D and slic3r often start new layers with holes. Post a link to the github discussion, I will certainly look into it more. Thank you for your comment!

They are all top.

Hi all, I have been using cura off and on for the past year or so but haven't used it in quite a few months. I came back to it and my last settings which worked, no longer do and I cant seem to figure this issue out. It mostly occurs on holes but the perimeters don't touch. Besides not touching, the holes look horrific. With S3D and Slic3r, i can print the models just fine, but there's something off when I try it with cura. I've uploaded a few pictures for you to see. Unfortunately i have recycled the worst ones, and kept the best ones, but the issue is still present. ----- Things ive tried: Increasing/decreasing flow Speed/accel/jerk adjustments Different filament ----- Any help is much appreciated. Thanks!!!

Yes, it is possible to print very well with PETG on the the UM3. I started with the generic ABS profile, and went from there. The settings I played with most were temperature(filaments recomended temp), and a tiny bit flow. The retraction settings themselves seemed to work great without any modifications. As for the rest of the settings, they've already been optimized by UM, so you don't really need to change them. Hope this helps Ryan
