I have a small (1" x 3/4") part that I'm printing in ABS. You can see from the images below that there are quality issues with the ABS prints (white, on left), which were exported using the Cura "high quality" setting. The part on the right in grey were printed in PLA several months ago.
It looks like the area around the holes are not filled properly, and the material flow is not consistent, as the surface is not smooth.
I'm using default settings for ABS (100% speed, 110C buildplate temp, 250C nozzle temp).
Any advice on how to fix this?
