The extruder falls down at the end of the print

If at the end of the printing process the three steppers motors get disabled, the extruder may fall down and hit the printed object. This is caused by a command at the end of the Gcode, intended to save energy on Cartesian printers.

Disable the M84 command from the “END GCODE” section in the slicing software ( just add a semicolon before the command. Example: ” ;M84 “ ).
