Hi,
I wonder if anybody could help me diagnose this? On recent prints of this particular piece (at this size) im experiencing bad layer shifting. Ive tried with another filament, and have got similar results. Previously though this print has printed just find though (as you can see in the photo). Interestingly other prints seem to be printing just fine without any shifting (same filament).
Im a little confused and was wondering if anybody had any suggestions? Ive done auto bed leveling and flow calibration. Have also lubed the axis recently.
Thanks for any help you can give!
Nick
You have some sort of extrusion issue
The bulges near the curves make me think pressure advance / k factor / flow dynamics (diff names, same thing).
The gaps in the extrusions also make me think flow RATIO is too low but it could also be something like a partial clog.
If all else fails, double check the screws on the heating fixture for tightness, slop in this shows up systemically all over in wierd ways .
Find a guide if you need, but unscrew these 3 screws completely, flip the black plate down, tighten these 4 screws
