# 3D Printing Log This log contains a list of events (most recent first) in using and maintaining my 3d printer. For larger upgrades, see [[Prusa Hardware Upgrades]]. ## Prusa Mk3.9 (See also [[prusa-mk39-8db42a]]) - 20251224 cleaned the extruder gear - Recent ASA prints have looked "wobbly". Same behavior when I took the printer off the shaking table. Same behavior when I switched to PLA. Cleaning the extruder gear didn't help with this but did help with failed prints. - 20251224 started this log
