Abstract

This little helper converts HPGL files generated by InkCut to GCode.

Limitations: HPGL

The functionality is very limited and only understands the following HPGL commands:

• IN (initialize, ignored)
• PS (pen select)
• PU (movement with pen up)
• PD (movement with pen down)

Limitations: GCode

The following assumptions were made:

• HPGL pens are indexed starting with 1, GCode indexes tools starting at 0. This was mapped with a hard offset of -1.
• Machine is assumed to be in absolute coordinate mode (s. init file)
• Machine is assumed to be initialized to using millimeters (s. init file)
• Work coordinate system is assumed to be zeroed on work surface

Feed rates, z plunge depth and z-hight over work piece for rapids can be configured in the perl script.
