Ultimate lash calibration piece

thingiverse

tired of "print -> measure -> adjust -> repeat" to calibrate the backlash of your axis? Here is the definite calibration piece: print once for each axis, no calipers required. Instructions These are basically just straight parallel lines along the axis, with pieces offset by a predefined and increasing amount - in the uploaded STLs it is 0.03mm*linenumber. Just print (with lash plugin deactivated!), then count the lines up to which you can't see the steps in the middle (starting from 0), multiply by 0.03 and you have your backlash. modify to your heart's content, openscad source included.
