MK8/MK7 Nozzle Cleaning Script

thingiverse

Clean your MK8/MK7 stepstruder nozzle with this handy script that prints a cube with a nozzle-shaped indentation inside it, gradually burying the hot nozzle within. Once the nozzle cools to 70°C, move the platform away and use pliers to remove it for a shiny, clean nozzle. Credit goes to Crazy Jaw for the original idea on the MakerBot forum. Exercise caution as using this method may exert force on your bot's mechanics; preheat if necessary to prevent damage. For Replicator (5.5 Firmware) users, choose CleanMK8Left.gcode/CleanMK8Right.gcode for non-accelerated and CleanMK8AccelLeft.gcode/CleanMK8AccelRight.gcode for accelerated extruders; left refers to the left extruder, right to the right extruder. If you have a single extruder, download "Right". To clean two extruders simultaneously, download "Left" and use a dual printing script or "Firmware Ditto Printing (TBA)". Thingomatic (Jetty Firmware) users should use CleanMK7.gcode, with Jetty firmware recommended; customize gcode for other firmware, machines, or non-stock configurations by rebuilding the .stl file using 25% fill and 5 shells, then following the gcode example attached to this thing at the ends of the files. Remember to take the time to make it a derivative and click "I Made One" if you use the script.
