How do you avoid the slicer running your gears together like this?
Was using Slic3r in this case.
You could move the gears further apart or reduce the extrusion width.
Gear teeth made with that fine a pitch compared to extrusion width seems like asking for trouble anyway — have you tried printing these gears solo to see whether they match your strength expectations even without the glitch?
Changed the extrusion width
@Peter_Hertel I did both and got slicer to work. Still getting teeth running together during the print, so may need to take it back even further.
@Jasper_Janssen I suspect I may need to go up a size in teeth.
Another trick I found is using dental floss for separating printed teeth.
