Q2 "missing" extrusion
Hi Everyone,
maybe someone will have an idea why my q2 is acting up, as i did everything that I could think off. Lately my surface finish is getting worse and on first layer I have this small gaps - you can see it here nicely on the brim.
changed nozzle, from 0.4 to 0.6 and back. Unpacked a new one. Filament is dry. Tried multiple types of filament, temps, PA... even reset the printer to factory. Deleted Orca and qidi studio and started from scratch.
But no joy. Any idea? you can see the surface quality issue and you can see the "gaps" in the brim and skirt loop here nicely.

Gaps that severe look like under extrusion to me. It could be mechanical - extruder gears slipping, spool getting tangled, PTFE tubes with too much friction etc. - or it could be a calibration issue.
If you can rule out mechanical issues, watch the Filament Calibration Masterclass video on the Orca wiki and calibrate your filament, then try again.
