		/* coordintes units:
		* Coordinates are measured either in inch or metric (millimeters).
		* Inch coordinates are in six digits (00.0000) with increments as small as 0.0001 (1/10,000).
		* Metric coordinates can be measured in microns (thousandths of a millimeter)
		* in one of the following three ways:
		* Five digit 10 micron resolution (000.00)
		* Six digit 10 micron resolution (0000.00)
		* Six digit micron resolution (000.000)
		*
		* Leading and trailing zeros:
		* Excellon (CNC-7) uses inches in six digits and metric in five or six digits.
		* The zeros to the left of the coordinate are called leading zeros (LZ).
		* The zeros to right of the coordinate are called trailing zeros (TZ).
		* The CNC-7 uses leading zeros unless you specify otherwise through a part program.
		* You can do so with the INCH/METRIC command.
		* With leading zeros, the leading zeros must always be included.
		* Trailing zeros are unneeded and may be left off.
		* For trailing zeros, the reverse of the above is true.
