Calibrate X Y Z

thingiverse

I designed these prints to speed up calibrating my X, Y, and Z axes quickly and efficiently. First, print the "calibration test" file with conservative settings such as slower speeds and thinner layers for more accurate results. Next, measure all the axis of the print using the included drawings that list the dimensions of the parts. Then use this formula to calculate your new E Steps value: Desired Measurement / Actual Measurement x Current E Step Value = New E Step Value. For example, if the z-axis measurement is 19.86mm and the current E Step value is 80, you would plug in these numbers like this: 20 / 19.86 x 80 = 80.56. Finally, adjust your firmware or printer controller to the new Z axis E Steps value of 80.56. Repeat this process for each remaining axis. You can change the E Step value either in the printer controller or in the printer firmware. There are numerous YouTube videos that explain how to do this - watch several until you feel confident with the procedure. You can also use the "Calibration Circle" file to adjust your slicer's horizontal expansion setting. Changing this setting allows for adjustment of circles and hole printing so they print flat and true to dimension. This method is best suited for small-scale calibration, accurate within the size of the print sample. If you calibrate with a small sample but then print something 10 times larger, the calibration will likely be off. So my advice is to adjust your calibration objects to match the approximate size you'll be printing or simply calibrate the whole bed and be done. I'm not patient enough for that!
