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?
We need to start to fill up lemmy :) Can you solve this issue? My HEVO (Hypercube Evolution), now 5 years old started to have very weird banding. It has a Bowden BMG Extruder and a E3D V6 printhead with CHT-Nozzle. MKS Robin with TMC2209 and Klipper. Benchy is ABS, lower one is HIPS. Printed at 230°/105° bed. part cooling fan off. I took apart and cleaned the extruder. The gears look intact and i can move the extruder by hand without binding. I found the E3D V6 was loose. I retightened it, which didn't solve the issue. I'll spend a beer to the one that solves this issue ;) Edit: Found the Issue: hotend not hot enough.
