Build Platform Level Test Pattern

thingiverse

To ensure accurate build platform alignment for successful prints, utilize a thin calibration object measuring 0.25 mm layers that needs to be leveled within +/-0.05 mm across the entire platform. Employ this OpenSCAD program to generate an object with bars one thread tall and two threads wide, which will be converted into G-Code by Skeinforge or your preferred slicer. Printing this short and thin plastic extrusion reveals misalignments. However, remember to modify the OpenSCAD source according to your printing parameters for correct G-Code generation. Measure the bars' thickness with calipers; any discrepancy indicates adjustment requirements at specific screws. Additionally, ensure that the overall printed width of each bar matches the Skeinforge W/T setting and observe the tabs indicating axis directions for corrections.
