In this video we go over how to square and calibrate your CNC machine after installing dual endstops. This tutorial is for the original MPCNC running Marlin 2 but can be adapted for many other CNC builds and softwares including the MPCNC Primo and GRBL.

If you want to automatically draw the lines, use the following gcode with the pen starting in position to draw. Adjust the X and Y values with an ! to the maximum on your machine:
G1 X0 Y0
G1 X!
G1 Y!
G1 X0
G1 Y0
G1 X! Y!
G1 Z5
G1 X0
G1 Z0
G1 X! Y0
G1 Z10
