Kossel 3D printer (Anycubic linear delta) bed leveling

thingiverse

This is my first trial to solve the problem of no automatic leveling. I tried to make it challenging, but still not sufficient for precise leveling. It works, but I was dreaming of being able to keep the calibration even after removing the bed because I had extra nuts (the thin ones) to lock it. Another side effect is the reduced printing area. With new adaptors I had to set up Cura with 150mm instead of the original 180mm (but I really don't think this printer would be capable of printing something close to 180mm in diameter). Hint: If your printer is not very precise, scale up the nuts inside Cura (or Slic3r) before generating the g-code. I suggest scaling only X and Y dimensions by 101% (or a scale factor of 1.01). How to assemble it The Nut_counter is the first nut from bottom to top. If you look at the first photograph, you may see it. It's supposed to lock the big, tough nut. Step-by-step: 1) Attach the Base to your printer (you should center it in relation to each triangle vertex). 2) Add the Nut_counter and put it all the way down to free the way. 3) Add the Nut. 4) Add your printer bed. 5) Add the Nut_small_new. 6) Level the bed using the Nut and the Nut_small_new. 7) Use the Nut_counter to lock the Nut. 8) Print the AnycubicTestRing140 to verify if it's working. I also paused the printer to correct the bed level during the very first layers. Be careful, depending on your setup for brim/skirt, your printer may hit the bed levelers when printing the AnycubicTestRing140 test file. I've changed my Machine settings to a bed with a diameter of 150mm to avoid surprises. This bed leveler is not a very good solution because it's quite hard to get the leveling right and if you remove the bed plate, you'll need to redo it. In the future, I will design something better that allows me to attach an extra removable bed plate or, even better, remove the one I have without ruining the leveling.
