I am trying to print some solid ‘U’ shaped brackets with 20mm (inside) sides to clip on to some 20mm box profile. The clip is currently 2.5mm thick. The first one printed fine but I slightly increased the lug diameter (not wall thickness). When printed again it came out as a shell and completely hollow. After trying many setting the one that has most effect on this is ‘layer height’. Either increasing by .01mm or decreasing can improve the problem but not eliminate it. I could understand if it had to leave out a single extrusion due space but it leaves out about 5. Sometimes it attempts to infill with dots but they don’t do anything to hold it together.
Bizarrely, if I adjust the layer height to get the best infill on a single bracket, then place 2 of them on the bed the infill goes wrong again and needs adjusting.
I understand a smaller layer height might produce a wider ‘squished’ filament but putting 2 identical objects on the bed shouldn’t mess that up?
edit, I should add that it is not a printer problem. I check and fix the gcode display before wasting ABS - well most of the time.
