Hi,
using following settings in "other" tabs:
<toolChangeRetractionDistance>7</toolChangeRetractionDistance>
<toolChangeExtraRestartDistance>-0.5</toolChangeExtraRestartDistance>
<toolChangeRetractionSpeed>600</toolChangeRetractionSpeed>
sometime the extruder position is reset without restart extrusion:
G1 E-7.0000 F600
T2
; feature prime pillar
G1 X68.614 Y102.356 F6000
G1 X66.962 Y104.599
[...]
G1 X77.528 Y139.453
G92 E0.0000
usually there is a "G1 E-0.5000 F600" before the G92 that is missing twice in my G-code (104 tools changes, 102 are Ok, 2 wrong).
