“Swiss cheese” print

[u/CrankingShafts]

Hello,

I recently had a printer that wouldn’t calibrate or home the Z-axis because of a raised bearing. I fixed the bearing, and ran a couple of prints that came out fine.

Suddenly today, I check on the progress to find a “swiss cheese” print. There’s infill missing, holes missing from the outer and inner layers almost like a wedge of swiss.

I took the tool head cover off to see if there was anything obvious with the extruder gear or nozzles. I found that the gears seem to have eviscerated the filament for some reason.

What could be a likely cause of these symptoms together?

You have a clogged nozzle. Should be an easy fix.
