I attached a couple pic's of a part in ABS i can't seem to get it honed in right, i have PLA printing fine.
The pic's are printed at 260 and 250%c but around the though holes seems to be hollow the width of the hole.
I have printed a square cube 25mm and that looks good all around, just seems to get bad when i start the bigger prints
its a delta printer with duet2 wifi
and i did dry the filament for 6 hours at 170
