Multi-Coloured Owl Key Tag

thingiverse

This is a key tag in the shape of an owl that I made for my niece. The interesting thing is that I did multiple color changes since I have a single extruder/head. I printed with 0.2mm layer height. I use Octoprint to manage my printer, so all I had to do was insert a M0 just before the start of the new color's first layer. The table below shows when I changed. Note that I don't use a raft, so I didn't need to allow for that. | Height | Before Layer | Changed to Color | | --------- | ----------------- | ------------------ | | 0mm | Start | Black | | 3mm | 16 | Grey | | 3.6mm | 19 | White | | 4.2mm | 22 | Red | | 4.8mm | End | N/A | I also have some GCODE scripts in my Octoprint settings that assist in color changes during a "pause". Here they are: *After print job is paused:* {% if pause_position.x is not none %} ; relative XYZ and Extrude G91 M83 ; retract 5 filament, move Z up 5mm G1 Z+5 E-5 F4500 ; back to absolute XYZE M82 G90 ; move to a safe rest position (X100,Y100), adjust as necessary G1 X100 Y100 {% endif %} *Before print job is resumed:* G1 E5 F4500 G1 E5 F4500 ; absolute E M82 ; absolute XYZ G90 ; reset E G92 E{{ pause_position.e }} ; move back to pause position XYZ G1 X{{ pause_position.x }} Y{{ pause_position.y }} Z{{ pause_position.z }} F4500 ; reset to feed rate before pause if available {% if pause_position.f is not none %}G1 F{{ pause_position.f }}{% endif %} Hope this was interesting/helpful. I'm Australian, so "color" is the correct spelling!
