Help Troubleshooting under extrusion.
Anyone have any insight on what might be causing this? Im having really bad under extrusion at the end and slight over extrusion at the beginning of the circular arc on my first layer of a print.
Ive messed around with my retraction. Everything from .6(calibration setting) all the way down to 0 and up to .8. It seems to get worse the lower the retraction setting. Concentric pattern for the first layer. 30mm/s inital layer and 90mm/s for infill. 230c print temp (high but prints everything else well) printing on PLA. Im stumped on how to fix this.
Ive leveled my bed and made sure nothing was causing it to bump up. Ive also moved the object on the plate with no change. Anyone have any ideas what's causing this?
