[SFACT] Retraction always 0.0 My prints have some stringing if i do a oozebane test. I noticed that the Gcode generated by SFACT V2.1 11.08.11 is always is E-0.0 G1 X-4.421 Y-14.25 Z1.6 F3600.0 E0.321 G1 F900.0 G1 E-0.0 G1 F3600.0 G1 X4.141 Y13.733 Z1.6 F7800.0 G1 F900.0 G1 E0.0 G1 F7800.0 G1 X3.733 Y14.141 Z1.6 F3600.0 E0.0065 This is exact the same as described in an issue on github: ahmetcemturan/SFACT/issues/8 This issue is closed with the comment to set the value 'minimum retraction before extrusion' to 0. Doing that unfortunatelly causes a division by zero error. Putting the value on 0.00000001 does not cause a division by zero, but gives the same code as showed above. Is there anybody who can help me to reduce stringing/ oozing?
