Multi-Coloured Owl Key Tag by danricho

Last crawled date: 4 years, 12 months ago

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 colour changes (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 colour'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.

I also have some GCODE scripts in my Octoprint settings which assist in colour 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 %}
{% endif %}
Hope this was interesting/helpful.
I'm Australian, so "colour" is the correct spelling!
