under extrusion, may have never recovered from an extruder blob
Hello everyone,
I'm trying to print Montana masks for healthcare workers and after 2 prints began seeing under extrusion and the parts seperating.
PLA 65deg c bed, acetoned, greased the extruder gears, cleaned the nozzle with the needle, increased the filament rate but I'm not getting anywhere. This is how loose the extruder is, have I perhaps damaged something when I removed an extruder blob of PET?IMG_5914

Here is a first layer calibration attempt. Started from 0.0 but it seems just not the normal amount of filament being extruded
thanks for any help.
I'm running the wizard again in the meantime

also its an upgrade from MK3 to MK3S and since then I've had consistency problems. First try at PEK had an monster extrusion blob, needed to replace temp sensor to extruder, but have had some ok prints since. Just Got through 2 sets of PLA montana masks and the last print was fine, but suddenly started not being able to lay down a first layer. It seems filament starts flowing then gets really thin/small volumn and the first layer messes up.

worked on z height and may have got somewhere. 1st layer and halfway through print and seems ok.
I'm an anesthesiologist and these masks are for fellow physicians in our hospital's covid ward.
Underwhelmed by support, but carry on
