Kossel manual bed-leveling system

thingiverse

A system to manually adjust the bed. It was originally designed for the Anycubic Kossel Plus. You can use it to manualy fine-tuning the layer height at three points around the bed. I use it for a few weeks now and find it a relief to use. Having nice first layers since i mounted it without any trouble. You can use it besides your normal bed-leveling routines. You lose some build-height (10 - 15 mm). The build-diameter is almost unaffected, while the system still keeps the bed firmly in place. It consists of 4 printed parts. with the slider-A part you have the choice of a version that works with a brass insert (M4, 5mm high and 6mm diameter) and one where you can screw the thread yourself (also M4). To make it as sturdy as possible there is no extra tolerance between the sliding-parts of slider-A and B. You probably has to file it a little down until it slides without wobble. After mounting the three clamps you can use the horizontal screws/bolts to secure the bed. It sits like a rock and due to the material there is also a little springiness in the system. Two simple to use GCode-files are attached for setting the bed over three points (240 mm diameter). For more information and Gcode for smaller bed-sizes see https://www.thingiverse.com/thing:3829487 Update 25-oct-2019: Pyz and Pzx where swapped in the Gcodes. Doesn't influence the outcome but it is repaired. Happy bed-leveling :) --- First time use (Marlin 1.1.9 and maybe earlier) : -Lower down the clamps as low as possible and up again with 2mm -Attach the probe and set the Delta Height (prepare -> Delta calibration and Store) -Lower the bed manually 1 mm over all three points -Remove the probe and run the gcode to adjust the bed manually. -Attach the probe and run autocalibration and bed-leveling (store). -Run a print and from now on you can manually tinker the Z-height. Fist time use without a probe: -Lower down the clamps as low as possible and up again with 2mm -Use a paper and lower the Z until it touches the paper on the bed. -Subtract the current Z-height from the Delta height (store). -Lower the bed 1 mm over all three points. -Run the Gcode to adjust the bed manually. -Repeat the Gcode at least one time
