The dreaded Bowden OOZE!
I’ve recently changed my extruder from Direct-drive to a bowden style extruder. My prints are looking much better from the elimination of weight on the Z Gantry (The extruder setup was quite heavy.) however, I’m faced with the issue of ooze. I understand the relation between hysteresis and distance between the drive gear and the hot-end. I’m wondering if anyone’s managed to come up with a solution?
I’ve tried extending my retraction length (up to 7mm) and increasing the speed (up to 60mm/s) but it doesn’t seem to have any effect. I’m also getting blobs at the perimeter seam, I’ve adjusted my jerk settings, checked my extrusion steps/mm which are all within tolerance.
I’ve also read theres a setting in Marlin’s Configuration_adv.h:
#define FWRETRACT // not fully tested
is this an option? Has anyone enabled this setting, then enabled firmware retraction in Slic3r?
anyone have any suggestions? Sorry for the poor picture quality.
Thanks in advance,
