SuperCam can be used to draw and operate machines using metric measuring units.  CorelDraw 7.0 can be used with metric millimeter units of drawing to create HPGL files to be used as toolpaths by SuperCam.

In SuperCam, the X, Y and Z step distances must be expressed in metric units. The “setxysiz” and “setzsize” commands are used to do this. The size in millimeters can be found by dividing the step size in inches by .03937. Example a step size of .0025 inches/.03937 = .0635 millimeters, a step size of .000125 inches/.03937 = .003175 millimeters. Once the linear step distance has been expressed in metric millimeters the drawing units in SuperCamwill be Millimeters.

In CorelDraw, the menu path of “Tools|Options|General|Ruler|Units|Millimeters” will change the unit of measurement to Millimeters. Drawings can then be made using Metric Measurements. To use the drawings as toolpaths, execute the FILE|EXPORT function, with the file format of HPGL selected. A .PLT file is exported into the “SuperCam” sub-directory. CorelDraw‘s export parameters can be adjusted for the best output and sizing. Recommended settings are, Origin, at page bottom left,1016 increments per inch, 100% scale and no fill. Even though the drawing was madeusing metric measurements, the metric measurements are translated into Inches and thenincrements per inch to fulfill the HPGL file format requirements.

The HPGL plot file is then imported into SuperCam. The standard HPGL import variables of SCALE = 1.000, INCR/Inch = 1016 will produce drastically under sized toolpaths. Change the INCR/Inch to 40 to get the most accurate drawing replication, the smallest drawing element will be 1/40th of a millimeter, 0.0009842 inch. By changing the increments per inch in CorelDraw to 2032 and the SuperCam INCR/Inch to 80, the resolution of the drawing transfer can be increased to 1/80th of a millimeter.

A good test to see if the files are being transfered accurately is tocreate a CorelDraw drawing with a 1 and a 10 inch square with the lowerleft corner at 0,0. After the drawing has been imported, use the SuperCam“LIST” command to verify that the end points are as expected, at 25.4 and 254millimeters.

Once the file has been imported, the plot file can be edited. Toolpaths can be moved, copied, rotated and scaled to fit best on the material they will be cut from.
