Workbee CNC Converting to MGM12 linear Rails

thingiverse

This is the parts i made when i uppgraded the orginal workbee from ooznest to a machine with linear rails. maybye this will be helpfull for some of you that are going down that path. -Benefits: got rid of the wheels Higher z travel more presise can drive the machine faster and harder chattering in alu and brass is almost gone. Before you dismantle your machine, it would be smart to have milled out the drill jig in alu on your machine :) Parts to buy i bought most of the parts from bulkman3d, - Linear Slide Bearing Block MGN12h four on each axe so 8 in total - MGN12 Linear Rail I bought 2 on 30 cm and 2 at 1 meter (they need to 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 - 1, M3 * 8 mm to the tracks. buy a bunch - Linear Rail Sphinx CNC X Z Axis Upgrade Plate Set This you can buy on ebay from chrisclub1 really good quality. link: https://www.ebay.com/itm/Linear-Rail-Sphinx-CNC-X-Z-Axis-Upgrade-Plate-Set-seen-at-Openbuilds/254476035928?hash=item3b3ff42758:g:y5cAAOSw4OFeFo9C Tool.stl This is the alignment tool so you can get the MGM rails mounted right. cable clips spindel cable on xbeam.stl Just some nice clips that fits on the cbeam to mount the spindle cable . x endstop mount.stl This is the xbeam endstop mount i made to fit with the carrige on the rails. works very good. cable clips z endstop.stl Just to tidy up the cable managment on the z. dragchain mount onto the z axe.stl This mount is to hang the dragchain proper on to the z axe, now the dragchain lays ontop of the xbeam. the stand off that is to the stepper motor will fit snug into the pillars on this mount. End Stop block z axe on the zbeam.stl this is the endstop mount with a cable managment inside, mounts to the cbeam. you also have to make a alu or a 3d printed stopper on the x carrier plate. look at the pictures and you will see. workbee drill plate.dxf This is the plate i used to flip my cbeam. I milled this out of 10 mm alu, and it mounts to the holes of the stepper motor. This is for the screw to algin in center of the cbeam when flipped. The drill jig worked out fine, See pictures .
