I've wanted a CNC router/engraver for a long time and recently came across the MPCNC (Mostly Printed CNC) from V1 Engineering (https://www.v1engineering.com/specifications/) and this look like just the ticket.
He sells complete kits or you can download the stl files to 3Dprint your own, which is the route I took.
Besides printed parts you need a bunch of bolts, nuts, and bearings as well as Arduino Mega and CNC Shield, stepper motors, proximity switches, 3/4" electrical conduit and a spindle/router.
There will be more to come as the project progresses and hopefully some awesome products to offer in my shop.
keep an eye on this page for more to come
