Multi color print without an MMU on MK3S¶
Hero Shot of the Week¶
Summary¶
How to print a layer that has multiple colors.
Work Process¶
Introduction¶
So this was in a workshop at Fab25 that I followed. It was quit quick so my notes were mostly about it exist. So I searched on how to do it and found this guide.
My work¶
Making the model¶
To make the model I just created a cube inside Prusa Slicer
Right click > Add Shape > Box
Resized my cube with to have the correct size (a flat board).
Than downloaded an SVG file. Modified my cube with the SVG file
Right click Cube > Add modifier > SVG
Prusa Settings¶
(final version so that you do not make the same mistake as me).
You will need to be in expert mode !
Enable multiple virtual heads:
Printers > General > Capabilities

In the Extruder X (where X is a number) you can change the color so that you can better visualize what you want.
Than go to
Printers > Custom G-Code
Find the Tool Change G-Code Section and copy-paste the following line:
M600; Filament change
Printing¶
So I first went with the settings that I wrote down and remembered. It almost worked.
The only issue was that it did not asked for manual filament change so everything was white.
Than I found this guide. Corrected what I missed and it worked.
The only issue is that when I do a filament change it, at one point to clear the head or the color it extrudes a ton of filament in one place. Than moves over it. But as it first extruded a big lump it X / Y crashes...
So I accidentally removed the color change print place (or however you want to call it) while trying to flatten it a little.
This is getting risky. Some stuff might go where it isn't supposed to.
