Anyone have any idea what might cause this sort of issue on PLA? I run into it frequently, but pretty much only when all of the following points are true:
- the print has multiple parts, so the extruder spends a decent amount of time off of any given part (only one part from this print is pictured)
- the affected part(s), like the picture above, have a relatively steep outward overhang, extending over the build plate
- the outward overhang part is relatively narrow, as seen from a top view
This is from a printer with a 4028 fan (i.e. pretty massive airflow, server type fan) so even the 35-45% (based on layer time) I have it currently set at is more than 100% with single/dual 5015's or etc.
I guess my other option is to try supports, but this doesn't really seem like a situation where supports should be needed. Anyone ever had a similar problem and solved it without just turning the speed waaaayyyyyy down?
