Printing Generic PLA at 210C, bed at 60C.
extra fast 0.3mm",
AA 0.8 Nozzle,
4 * walls at 0.8 (for strength).
Some of my vertical holes have a gap between the inner layer and the infill. It's a bit concerning as I need to thread these with a tap after printing.
Looking at the print preview in Cura it seems to be OK.
Any suggestions would be greatly appreciated.
