Extruder retracting filament at start of print OK, I've looked everywhere, what setting would make skeinforge retract an inch or more of filament at the start of a print? I can't see or understand what in the g-code would cause this. Anyone have an idea as to what setting might cause this? https://reprap.org/forum/read.php?154,174758,174758#msg-174758 Wed, 17 Jun 2026 16:13:46 -0400 Phorum 5.2.23 https://reprap.org/forum/read.php?154,174758,176056#msg-176056 Re: Extruder retracting filament at start of print https://reprap.org/forum/read.php?154,174758,176056#msg-176056

G92 E0 (as said by Jbernardis)
G1 X100 Y100 E-3.0 F4500 (going to the center of Mendel's plate and retracting filament for 3 mm)

After that, gcode written by Skeinforge automatically pushes the 3 mm just before printing.]]> François Delègue Skeinforge Fri, 11 Jan 2013 03:33:29 -0500 https://reprap.org/forum/read.php?154,174758,175092#msg-175092 Re: Extruder retracting filament at start of print https://reprap.org/forum/read.php?154,174758,175092#msg-175092 dbarbe Skeinforge Sat, 05 Jan 2013 20:06:16 -0500 https://reprap.org/forum/read.php?154,174758,174768#msg-174768 Re: Extruder retracting filament at start of print https://reprap.org/forum/read.php?154,174758,174768#msg-174768
Without this command, the E axis will retain the value from whatever it was doing before - including manual extrusions.

I got burned by this very early on when I switched from Slic3r to skeinforge, except my retraction wasn't just an inch. It retracted at a relatively high speed for a good 15 seconds. It took quite a bit of effort to get the hobbed bolt cleaned out.]]> jbernardis Skeinforge Thu, 03 Jan 2013 21:27:26 -0500 https://reprap.org/forum/read.php?154,174758,174758#msg-174758 Extruder retracting filament at start of print https://reprap.org/forum/read.php?154,174758,174758#msg-174758 dbarbe Skeinforge Thu, 03 Jan 2013 20:18:07 -0500
