Weird retraction problem. How is my end G-code?

westech

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

@westech

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.

@fcwilt M83 is for relative extruder mode.

Thanks for catching my typo.
