Hackaday alumni [Will O'Brien] sent in a few projects he’s been working on lately while he’s in the process of upgrading his workspace. He’s building a 1200 x 1200 mm CNC router based on the Shapeoko router, and it sure looks like he’s having fun doing it.
The Shapeoko router is based on the Makerslide open source linear bearing system. This system uses common aluminum extrusions as the frame of a very simple, very inexpensive CNC router. The Makerslide system is designed to be expandable; if you want a larger axis, just bolt in a longer piece of aluminum extrusion. We haven’t seen many Makerslide builds take advantage of this fact, a shame as the stock Shapeoko only has a build area of 200 mm square.
[Will] is expanding this build area to 1200 mm square, but of course this means beefing up some parts of the build. He’s already moved up to very hefty 250 oz/in Nema 23 stepper motors (up from the Nema 17s for a standard Shapeoko), as well as beefing up the motor mount a great deal.
[Will] also sourced a few lengths of cable drag chain (yes, that’s what it’s called) to keep all the wires for his huge CNC routers out of the path of a moving gantry and spinning motors. It looks like he’s got a very nice build shaping up, and we can’t wait to see it in action.
