Tuning seams again. In order to get them better I need to reduce retraction, to reduce the time at layer change. I can't seem to get the seam much better than this, at this speed/acceleration.
ABS. 500mms/50K/40SCV, 275C, .01ST, .006PA.
Having a retraction of nozzle diameter was causing a delay at layer change, enough to cause under cooling for the most part.
The seam width, under higher speeds/accels, seems to get wider. I have not yet figured out how to close it. You can see the bulge in front and after, as though the plastic is out of synk.
Is the filament being dragged or is it's mass giving it some velocity that does not follow the toolhead?
