HIC Prusa i3 Custom Firmware/ bed level/ metal to metal zmin

thingiverse

Updated firmware for the HIC Prusa. The auto bed leveling feature is available, but not the servo arm feature due to my custom setup method involving splicing z endstop wires to the aluminum bed and x carriage, which triggers zmin when both make contact. This setup has worked flawlessly on my machine so far; however, please report any errors so I can update my firmware accordingly. If you only want the standard firmware without auto bed leveling, add "//" in front of "#define ENABLE_AUTO_BED_LEVELING". You can find a detailed video on YouTube: https://www.youtube.com/watch?v=rS_nvMX6wzM&feature=youtube_gdata. For metal-to-metal zmin detection, you will need to remove the existing z switch stop and just connect the wires. An aluminum bed is necessary for proper function. Connect one end of the closed ring to both wire ends using solder or a crimp, and make sure the wire clearance allows proper travel movement. Install the other end of the ring to your x carriage, which should be made of metal and contact the hotend for effective level detection. Neatly tuck your wires to ensure they clear all parts. To activate auto bed leveling, add "G29" after "G28" in your start/end gcode, with G28 being present without any accompanying values. If there's a separate line of code followed by Z0, delete the entire line to ensure G28 and G29 remain standalone. Simple, right? Tips: Add Elmer's glue on the aluminum for effortless measuring without using blue tape. Ensure nozzle cleanliness during measurement initiation, especially in the early stages. A 180-degree orientation has been proven effective so far with no plastic seepage. I'll post a video once the response count grows; thank you in advance!
