3-Axis Calibration

thingiverse

I created this test piece to ensure the X, Y & Z axes on my printer are properly aligned.\r\n\r\nThe part features a notch at 50mm on all axes and an overall length of 100mm on each axis, allowing me to assess if any inaccuracies worsen with increased travel distance, i.e., is the percentage error at 50mm the same as at 100mm?\r\n\r\nI designed it with rounded edges to minimize edge bulges from affecting measurements. While I'm unsure of its effectiveness, this shouldn't impact printing anyway.\r\n\r\nWhen slicing this test piece, position the Z-axis section correctly by referring to the attached photo. The Z-axis has two protrusions halfway up, unlike the single lump on both X & Y axes.\r\nI inadvertently failed to do this initially, which is why I'm mentioning it!\r\n\r\nMy CAD package's coordinate system differs from Thingiverse's standard, and I haven't figured out how to adjust my designs for proper display within Thingiverse yet.
