suitable artcam post processor

Hi All,

I am using artcam to generate G-code for my machine , I don't know what is the suitable post processor to run on linuxcnc
I tried mach2.cnc but its very slow in circles
And tried G-Code Arcs.tab its fast in circles but in squares make a problem ... please check problem in attached photo

Thanks

I tried mach2.cnc but its very slow in circles

It probably uses lots of small segments to make an arc, which is slow because the controller executes each as a seperate move, there is no flow from one end to the other
as with a properly programmed G2 or G3

see www.linuxcnc.org/docs/devel/html/gcode/gcode.html#sec:G61-G61_1 and next section G64

The amount of rounding at corners can be controlled by these settings.

However you will probably have to adapt one from another CAM that is something near your output (Mach is normally not too far off)
