Dual Head XY Offset Calibration Tool

This tool is designed to assist with dual head nozzle offset calibration. You can customize this for your desired layer height, and also create a smaller or larger tool as per your requirements.

Within the customizer, selecting "extruder1" will always print the same thing regardless of the selected offset. By printing 0.2, 0.1, and 0.5 offset things for "extruder2" composited with the base from "extruder1", you can home in your offset calibration to 200, 100, and 50 micron accuracy in 3 steps, providing that you have a reasonably accurate starting point.

The tool is designed to home in with the minimum of filament used, opting to print only two layers at the configured layer height, thus completing quickly also.

I hope it helps someone out there.
