Auto bed leveling for Wilson

thingiverse

These are the critical parts required to incorporate automatic bed leveling into the Reprap Wilson (or any device employing the direct drive extruder from that project). The design is compatible with both the standard fan duct (Jhead hot end) and the larger one used with the e3d-lite6. Video documentation of assembly along with an in-depth explanation of the firmware modifications can be found at: https://youtu.be/qsmwGBuHoBU. Additional requirements include a 9g servo, snap-action limit switch, M2 screws and nuts, and a few zip ties to maintain organization. Instructions: 1. Attach 70cm wires to both the endstop switch and the servo motor. 2. Mount the endstop switch on the arm and secure cables using a mini zip tie. 3. Connect the servo holder to the servo motor utilizing the small white actuator that comes with the servo, securing it with a flat head screw (which should be included with the servo). 4. Attach the servo to the larger plastic piece as depicted. Secure it using an M2x16mm screw and M2 nut. Ensure wiring from the servo is routed through the hole on top of the servo mount. 5. Lock down wires from both the servo and endstop switch to the servo mount utilizing a second mini zip tie. 6. Remove the two M3x30mm screws from the hot end mount. 7. Eliminate the two M3 nuts that retained the hot end mount screws. 8. Insert the M3x30mm screws through the extruder body, loosely attach M3 nuts, and then press the servo mount downward to engage; tighten firmly. 9. Connect the endstop switch to the Z-min connection on RAMPS. 10. Attach the servo wires to the servo-1 connection on RAMPS. 11. Verify that the servo power jumper is installed on RAMPS. 12. Re-flash Marlin with auto bed leveling incorporated into it. Further details regarding the setup of Marlin will be provided in a forthcoming update.
