I've been thinking about converting the Mendel max to use a Bowden system. A first I'm going to use a single filament, but I definitely want to do multiple print heads for dual extrusion and more later.
I'm going to try the pneumatic press fitting first, and I also took another look at the quick change carriage. If I create the carriage that I mount the extruder on it will give me the same x travel as what I'm using now. On advantage is that I'll be able to switch between the Bowden and a regular one as I do my testing so I'll always be able to print if I need to. One other advantage is the fan mounts on the side so it's easier to see what's printing.
I'm hoping to have everything ready to install by this weekend and do my first test prints.
