Workbee CNC Converting to MGM12 linear Rails

thingiverse

This is what I've made after upgrading the original Workbee from Ooznest to a machine with linear rails. Hopefully, this will be helpful for some of you who are heading down that path. Benefits: I got rid of the wheels. Higher Z travel More precise Can drive the machine faster and harder Chattering in aluminum and brass is almost gone Before you dismantle your machine, it would be wise to have milled out the drill jig in aluminum on your machine. Parts to buy I bought most of the parts from Bulkman3D, - Linear Slide Bearing Block MGN12H: Four on each axis, so eight in total - MGN12 Linear Rail: I bought two at 30 cm and two at one meter (they need to be cut anyway) - Sliding T-Nut for 2020 V-Slot/T-Slot M3: To fasten the rails to the beams, buy a bunch - M3 Cap Head Screws: One, M3 * 8 mm to the tracks. Buy a bunch - Linear Rail Sphinx CNC X Z Axis Upgrade Plate Set This can be bought on eBay from Chrisclub1; really good quality.

It works very well. cable clips z endstop.stl Just to tidy up the cable management on the Z. dragchain mount onto the z axis.stl This mount is to hang the dragchain properly onto the Z axis; now the dragchain lies on top of the X-beam. The standoff that fits snug into the pillars on this mount will also fit the stepper motor. End Stop block z axis on the zbeam.stl This is the endstop mount with cable management inside, mounts to the C-beam. You'll also need to make an aluminum or 3D-printed stopper on the X carrier plate. Look at the pictures and you'll see. workbee drill plate.dxf This is the plate I used to flip my C-beam. I milled this out of 10 mm aluminum, and it mounts to the holes of the stepper motor. This is for the screw to align in the center of the C-beam when flipped. The drill jig worked out fine; see pictures.
