Pretty Good Bed Leveling & Z-Stop Kit for Makerfarm Pegasus

thingiverse

This is a kit to improve the Makerfarm Pegasus printer's bed leveling with ease, requiring only an M3 bolt driver. It includes a set of innovative nut/spring traps for the heat bed mount, and a Z-axis end stop that is much more accessible than before. I don't have a wooden heat bed mount, but I included a set of traps for one, assuming the mounting holes are offset in the same dimensions. The Z-stop arm uses the HammerNut from CaptainObvious (http://www.thingiverse.com/thing:245103), making this retro-fittable with no need to disassemble the printer. From the trap-alum or trap-wood STL file, you'll get: 1) A precision-made nut & spring trap for the bottom of the bed (QTY 4) 2) A high-quality round spring cap for the top of the spring (QTY 4) From the zstop-arm STL file, you'll get: 3) A long t-nut "bar" for the Z-axis adjustment screw, with two holes (QTY 1) 4) An angled arm for the end stop switch, with the HammerNut on one end, and a mounting spot for the switch on the other (QTY 1) See below for assembly tips. The license is inherited from CaptainObvious' HammerNut. Print Settings: Printer: Makerfarm Pegasus 10 Rafts: No Supports: No Resolution: 0.2mm Infill: 100% for strength Post-Printing: Assembly Move your z-axis up a few inches to get some room to work. Remove the original Z-axis adjuster and retain the long M3 screw. Insert the reclaimed M3 bolt through one hole of the long t-nut, no tapping required. The t-nut will be "pointing" up when installed, so be sure that the driver will be on the top. Install the t-nut bar into the bottom of the x-axis extrusion near the X-axis motor, poking out about 15mm or so. Use a short M3 bolt to secure it into the rail using the hole in the other end of the bar. Next, secure the endstop switch to the angled arm. The switch should be on the side opposite from the HammerNut. This way, when the arm is mounted to the vertical Z-axis rail, it will line up to the adjustement screw we installed. To install the switch arm, line it up against the vertical axis and insert the HammerNut into the slot. Rotate the arm to the right to fit the nut in place. The arm should extend out to the right, just above the Z motor. Secure the arm with another short M3 screw. Install the bed traps and spring cups. The bottom trap will hold an M3 lock nut.
