Auto bed level Anet A6

prusaprinters

Alternative type of bed auto leveling sensor. It is only using the printer x-carriage to push a micro switch up and down. It does not use any servo or electromagnet, only the carriage movement. Lower the level switch by moving the x-carriage rightmost, then start the auto leveling procedure. Then raise the switch by moving back the x-carriage to leftmost. you need some firmware support for auto leveling. I'm using SkyNet3D firmware: https://sv-se.facebook.com/skynet3ddevelopment/ Updated axis orientation in the object file.

Two small PTFE-tube, OD 3mm, ID 2mm, length 18mm. These are used as linear bearing. 2. One screw M3x12 mm (spare part from Anet printer assembly). 3. One screw M4x20 mm. 4. One screw M2x12 mm (spare part from Anet printer assembly) 5. One micro switch 9x8x3mm (very small, salvaged from an old walkman... :) 6. One spring ~5mm in diam from a ball pen. 7. One square rod 2.5x2.5mm, 75 mm in length. It is a common welding rod for copper pipes. This needs to be bent in an s-shape in one end. See the SketchUp design for details. This is the most trickiest part... I've tried using a 3d-printed rod, but unfortunately is was bent by the heat from the printer head. Download and install "Skynet v2.3.2 fix 2". Also carefully read the SkyNet3D documentation for configuring and uploading the firmware and setup of the leveling procedure. See also the provided firmware configuration.h that I'm using. Connect the switch in parallel to the original z-switch. Adjust the switch limit set screw so the switch tip is above the nozzle when raised, and below when the switch is lowered. It is tricky to get everything working together. A tip is to use some kind of a foam layer or rubber sheet to save nozzle and bed from crashes when testing (it will happen for sure...).
