Which Post Procesor?

[Alexanders]

I have a problem executing arcs generated by SolidCAM. This problem occurs sometimes and is difficult to see due to the large number of other trajectories.
There is an arc (entry move), the end of which is the beginning of the next arc (finishing pass).

An example of a part of the G-code from SolidCam:

Code: Select all

N1 G90 G17 G40 G80
N2 G01 F420.
N3 G41 D1 X31.693 Y33.086
N4 G03 X30.803 Y34.185 I-0.995 J0.105  (entry move arc R 1mm)
N5 G03 X30.803 Y34.185 I-0.398 J-3.779 (circle D 7.6 mm)
N6 M30

Gives the correct result:

But if you enter even the smallest negative value of ToolDiameter in ToolTable, for example 0.0001mm, the second arc is not executed.

And no warnings appear.

Additionally: If replace G41 with G42 and make the corrector value positive, the problem will look the same.

Hi Alexanders,

Most post processors have an option to break full circles into semicircles. The problem with full circles is that it is somewhat vague whether the intent is a microscopic arc, that truncated to zero length arc, or a full circle. Please see if you have such option.
