QcadCAM ignores path direction
Posted: Wed Aug 07, 2019 10:33 am
Good day,
I have been using QcadCAM for 3 years now - recently noticed an issue with circles and direction of cutting. I don't know if the issue has always been there, but I only noticed it recently. It seems that the CAM processor ignores which direction you specify on the toolpath, and uses the codes G2 / G3 randomly. Attached DXF with multiple toolpaths all specified as direction-Conventional/Right.
When I export the G-code (using G-code offset (mm) as required by my machine) I notice the following:
N1860 G2 X-140.5 I-140.5 J0 F800
N1870 G2 X140.5 I140.5 J0
N1880 G1 Z5
N1890 G0 X100.7627 Y-100.7627
N1900 G1 Z-2 F200
N1910 G3 X-100.7627 Y100.7627 I-100.7627 J100.7627 F800
N1920 G3 X100.7627 Y-100.7627 I100.7627 J-100.7627
N1930 G1 Z5
N1940 G0 X90.1561 Y-90.1561
N1950 G1 Z-3 F200
N1960 G3 X-90.1561 Y90.1561 I-90.1561 J90.1561 F800
N1970 G3 X90.1561 Y-90.1561 I90.1561 J-90.1561
N1980 G1 Z5
N1990 G0 X128.5 Y0
N2000 G1 Z-3 F200
N2010 G2 X-128.5 I-128.5 J0 F800
G-code also attached.
Why would it create toolpaths for both clockwise and counterclockwise - when only clockwise paths has been specified? At this point I need to manually edit my NC files and replace all G3 with G2. And if I don't - I break router bits.
Please assist
