    It's a 450w 48v DC motor (looks like the 300w xcarve without it's mounting bracket) with a mach3 compatible speed controllr. 0-12k rpm based on a dial or a 5v pwm input. Er11 collet

    The motor, mounting bracket, PS & speed controller were about $100 as a set from ebay


    The controller is Grbl .9i on an uno with a Chinese engraving shield and 8825 stepsticks set to .75a

    Motors are 86oz openbuilds nema17 powered by a 19v 7a laptop brick

    Limit switches are 6mm proximity, at 90 degrees to motion so they can't crash. Basically a 1*1 L bracket passes the switch with about .5mm clearance enabling fast seek



    If you look closely you'll see that y&z are leadscrew while x is belted. that's temporary until we get another shipment of leadscrew.


    For folks wondering if Grbl+stepstick has enough power to be useful... It's plenty to snap a 1/4 shank so anything more is silly :)

    The wooden triangles on the outside corners were originally just quick alignment jigs. As I was working on it at the hackerspace several folks said they liked the steampunk vibe that gave it, so they may be expanded with more engraving.

    They're also good at preventing sharp corners from gouging you when loading it in the car. All the sharp corners will be getting MDF bumpers.
