Intro

End GCode is appended to the end of a print job to perform useful functions such as cooling the hot-end and bed, "presenting" the completed part, and shutting down the motor/heater power supply (where supported by hardware/firmware).

Home X Axis

G28 X0  ; home X axis to get head out of the way.

Cooldown the hot-end and bed ready for next print

M104 S120; Set Hot-end to 120C
M140 S40; Set bed to 40C

Shutdown the hot-end and bed completely

M104 S0; Set Hot-end to 0C (off)
M140 S0; Set bed to 0C (off)

Presenting the part

G1 X0 Y180 F9000; Feed the bed forward making removal easy.

Stopping the motors

Cut the steppers so you can manually move X/Y around to make part removal easier, remember to have a G28 in your [Start GCode Routine] for a good home before the next print.

M84; Stop the Stepper Motors

Shutdown power supply

M80; Power down main power supply

Custom End GCode
