Weird retraction problem. How is my end G-code?
-
Greetings!
Thought I'd ask here. I use Cura on an Ender 3. Trying a new fast profile. Same end g-code I have been using. But I've experienced the extruder retracting almost all the way up the bowden tube at the end.
I leaned the hard way on my next print when nothing was coming out.
Does my end G-code look okay?
G91 ;Relative positioning
G1 E-2 F2700 ;Retract a bit
G1 E-2 Z0.2 F2400 ;Retract and raise Z
G1 X5 Y5 F3000 ;Wipe out
G1 Z10 ;Raise Z more
G90 ;Absolute positioning
G1 X0 Y{machine_depth} ;Present print
M106 S0 ;Turn-off fan
M104 S0 ;Turn-off hotend
M140 S0 ;Turn-off bed
M84 X Y E ;Disable all steppers but Z

G91 sets relative mode only for axis moves.
For extrusion you need M82 to set absolute mode and M83 to set relative mode.

@fcwilt M83 is for relative extruder mode.

Thanks for catching my typo.
