• WELplot reads HPGL commands from .plt files. When machining parameters have been set WELplot generates G-code data in various formats which can be used by a range of milling machine controllers. WELplot works best with HPGL plot files created by TechSoft UK Ltd's Design Tools - 2D Design.

• Open a plt file and WELplot displays your design

• Select the Tool and enter the cutting parameters for each colour in the design

• Circles can be interpreted as holes to be drilled. Here we are drilling an 8mm hole with a depth of 10mm and using pecking.

• The order in which the cuts are made is under user control. In this example the black path will be cut last.

• When the machining data has been entered, the widths of the tool paths are shown using shades of grey to represent depth of cut.

• The final stage is to choose from the four output formats that WELplot offers

Note: not all CAD software can export HPGL plot files and those that do may have a very limited implementation of the HPGL protocol. We recommend that you use TechSoft UK Ltd's Design Tools - 2D Design
