Hi Sullie,
It is not all down to your version of Aspire.
Just as an example…
If you download a .dxf file and import it into Aspire then trace it to create a toolpath then that operation will copy any curves (comprising of many straight lines) into curves comprising of many straight lines. This situation can be improved by use of the Aspire ‘Curve Fit’ function which will, where possible, replace these many straight lines with true arcs. Overall this means that when the final toolpath is created (using the Mach2/3 Arcs… Post Processor) G2 and G3 commands will be used to replace the Many G1 commands which would otherwise be present. This produces much smoother motion from a CNC machine.
( Not a terribly good explanation but I tried ).
Tweakie.
