I added additional page of information related to Auto Squaring on page 7, refresh browser to see the latest.

Auto Square Homing will perfectly square a paired axis Gantry automatically upon power up or when operator is required to “reset home”. Auto Square Homing saves the operator time, makes the machine easier to use and provides consistency in part geometry day in a day out. For Auto Square to work these conditions must be met.
Rules for Auto Square Homing:
1.) Auto Square Homing does not compensate for mechanically out-of-square machine tools.
Integrator must “dial in” the Gantry axis so that it is MECHANICALLY SQUARE before setting up software Auto Square Homing.
2) The Gantry must be very close to square when the Gantry is in its “relaxed” position.
Integrator must verify machine tool is very close to square when he gantry is in it “relaxed” state (no torque needed to hold it in position) for auto square homing to function properly.
3.) The Gantry must be very close to square when the machine is powered ON.
4.) The Gantry must be very close to square before starting the Auto Square Home program.
5.) The Gantry Home Switches must not be square to the machine. The Slave side Home Switch must trigger first when the Gantry axis begins to seek Home position. Line them up with Gantry then offset slave switch 0.025” closer to the Gantry.
6.) CNC12 Mill version 4.14+ with Pro or Digitizing bundle. (Software Axis Pairing is not available with the Free version of CNC12)
