No Calipers Required X and Y Axis Calibration Puzzle

thingiverse

Designed to test X and Y calibration, this test will show you which axis needs work and by how much. NO CALIPERS REQUIRED! "NOTICE: This test presumes that your calibration is close on x and y and that your extruder is dead on. Filament size can effect internal holes and exterior diameter if not correctly calibrated. This is to reconcile the axis against each other and ensure printed parts will fit into each other as expected. The procedures mentioned here are my own and may have flaws I did not foresee." The parts are labeled with the axis they are printed on length wise. So, each axis and should show true. (Meaning the X Bar should fit the X slot even if the machine is off, same for Y bar and Y slot.) The bars start with 20mm long and work down to 19.7mm. All bars are 5mm wide. The slots are both 20mm long and 5.2mm wide (To allow you only test length). I will post a full write up soon on the exact procedure to use this test. Instructions The X bar should fit into the X slot. The ID of the slot is 20mm, the OD of the bar is also 20mm. (If they are too tight move down to the next size until you find the one that fits. Let's assume the X1 Bar fits the X slot.) Use the X1 bar on the Y slot. If it fits the same as the X slot then you are calibrated. If not continue. Too big (The smallest bar doesn't fit the opposite axis slot)- Your Y is not stepping as far as your X, increase the steps/mm. Too small (One of the printed bars does fit, but is too loose length-wise.)- Move up one bar size if possible. If not, the steps are to long for that axis. You will have to reduce the steps.
