3D Table Control

Am I a lazy guy? Well, not particularly, but I don’t like to do things that aren’t necessary.
I do a lot of 3DPrinting. I have built myself a BLV MGN Cube printer (thanks Ben Levy for this great design!) with a Duet2 Wifi board, and I’m very happy with it.


Only…..well, using a 3D-Printer is an easy job, once you’ve got yourself an .STL file, a slicer and a 3Dprinter you can go ahead and make something yourself. The only thing remaining is setting up the whole circus to get the 3D-Printer to produce something useful, not spaghetti.
