This small bit of code will automatically unload your filament after the print job is done.
If you change colors/types frequently, This could save you 5 minutes of setup time per print.
In S3D look for your ending script and add an E -30 to the line of code that moves your build plate to the bottom when done. As the build plate drops, the filament will unload.
NOTES:
This should unload the tool/extruder that that was last active.
Make sure this command is placed before the cool down phase.
Not for use with the nylon filament guide. The roll must be placed above the machine.
When printing the same color, don't forget to reload the filament. (I've done that a few times)
Example end script below.
; **** Replicator 1 / FlashForge Creator dual end.gcode ****
M73 P100 ; end build progress
G1 Z150 E -30 F1000 ; send Z axis to bottom of machine and Unload filament
M140 S0 T0 ; cool down HBP
M104 S0 T0 ; cool down right extruder
M104 S0 T1 ; cool down left extruder
M127 ; stop blower fan
G162 X Y F3000 ; home XY maximum
M18 ; disable stepper
M72 P1 ; play Ta-Da song
; **** end of end.gcode ****
For dual extruder automatic unload. Add these lines to your end script just after the build plate moves down.
