^ Sounds cool!
If you are looking for a decent desktop printer for cheap the Folgertech 2020 is good. It uses the same electronics as the MPCNC and a similar extruder to the one sold as an add on. It is a kit and requires a lot of assembly, but just like the MPCNC once you get it built and tuned up it is a good machine.
But if you already have a 3d printer (presumably that you used to print the mpcnc) then it would be cool to print a printer. I’d imagine it will take a while for vicious to design one and release it. He is good about not releasing bad designs.
