About this 3D model

This is the pattern we use to dynamically level the build plate. (Rep 2X) It seems to work much better than the paper method It gives a true idea of how the extruder will deposit the print. Gallery pics show warped plate possible fix (note at end of instructions) Pic 1: Print lifting on my warped plate Pic 2: Print lifting on my warped plate Pic 3: Straightedge showing plate warping Pic 4: Difference in plate level once nuts loosened (had to lower Z-Axis limit switch almost 0.200") Pic 5: Warp in plate gone once nuts adjusted.
