Cura 3.5+ has changed MM support. I'm working hard on a new version of the G-Code generator and the manual!
I saw a lot of similar design, but nothing worked well for me.
So I decided to design my own.
I did a lot of variations of standard designs and a lot a lot of tests.
The result is here. :)
It is small and it works like a charm. :)
I did already a lot of prints and still without any problems.
2018-08-15 - Removed all G-code files and added a link to an Online G-code generator
2018-08-13 - Added UNTESTED V2 of G-code files
Print it, assemble it, attach it on your printer.
When the joiner is attached on your printer. Warm up hotend, insert filament inside one of the tubes on "starting position". It should be around 1 cm before going into the connector (picture attached). Start extruding and count, how much you extruded. When the filament goes out, you are done. Just replace the parking position in the Online G-code generator with your number, set your waste block position and size and you are done.
3) Before/After printing
Before and after printing the filament has to be retracted to the "starting position"!
4) Settings for waste block/prime tower (Cura 3.4!)
Update position of the waste block in the Online G-code generator.
Set your slicing program:
Nozzle Switch Retraction Distance = 0
Relative Extrusion = yes
Enable Prime Tower = yes
Circular Prime Tower = yes
Prime Tower Size = 32
Prime Tower Thickness = 14
Prime Tower X Position = 50
Prime Tower Y Position = 150
Wipe Inactive Nozzle on Prime Tower = no
Wipe Nozzle After Switch = yes
Prime Tower Purge Volume = 0
Ooze Shield = (if you need)
5) GCode (Cura 3.4!)
