150mm Calibration L

They said that when you are calibrating the steps for your X and Y motors, that you should use a big as possible object for calibration, like 100mm. So if you have a bigger printer with a 200mm print bed, why not use a bigger calibration object?

This calibration "L" is 150mm x 150mm x 3mm in the XYZ. It is designed to print as fast as possible while still being rigid enough for taking measurements.

You can then calibrate your STEPS using this formula:

X,Y-Axis: [desired length in mm] / [measured length in mm] * [current STEPS]

So for this object "150" would be your desired length.

You get your current steps by issue M503 command to printer.

Create the new M92 command by replacing the X and Y values above with the new calculated values:
M92 X[calculated] Y[calculated] Z[what it was before] E[what it was before]
