Multi Sized Calibration

thingiverse

When I conducted a swift search for calibration, I stumbled upon the standard cubes or stack of cubes, but measuring three 5mm cubes that aren't aligned or using a single cube doesn't always yield the best result. In the past, I've simply downloaded something like a 25mm cube and resized it to take a second measurement. This time around, I decided to design the test print you see here. By doing so, I can measure 50mm, 20mm, 15mm, 10mm & 5mm all in one single print while ensuring they stay in place as well. Hopefully, this will be useful for someone out there too. To calibrate your printer using this model or another similar one: Let's say, for example, my printer is utilizing the value of "86.95" for the X-Axis steps per mm. However, the 20mm cube actually prints the X-Axis at a size of 22mm. We would apply the following calculation to obtain the correct steps per mm. Correct Steps Per MM = (test length * steps per mm) / actual printed length X-Axis = (20*86.95)/22 So, the above X-Axis now equals 79.04. Simply adjust this in your EEPROM or firmware directly.
