Multicolour printing with one hotend using hardware
Multicolour printing with one hotend using Slic3r
Multicolour printing with one hotend using Slic3r requires manually changing the filament, but the printer will stop at the required point and move the print head out of the way for you to do this so can be left alone barring the filament change routines.
Slic3r Printer Settings
Rather than modify your default settings, Slic3r allows you to create profiles to achieve different functionality.
Printer settings
Open Slic3r
Select Printer Settings
Click the Save icon next to the printer name
Enter a new name of Multicolour ….. whatever you want to call it
You will now have a new Printer setting alongside the original ones that Prusa supplies
Extruder settings
On the General | Capabilities Section is a heading Extruders
Increase the number of extruders as per how many colours you may want to print with on a single print based on the number of filament changes. You can have more extruders than you are going to use, 6 extruders is fine if only printing in 2 colours, Slic3r ignores the excess extruders.
Once modified you will see that the left hand Viewing Pane also now has 6 extruders
By default, if you select and of these extruders, you should not have to adjust any default settings from your normal printing.
Tool change G-Code
Now set a custom G-Code that runs for what Slic3r thinks is a tool change. Select Custom G-Code on the left hand Pane and then scroll down on the right hand side to Tool Change G-Code.
In the Tool Change G-Code box, enter M600 and click the save next to your printer settings name again to save all the changes made.
