    square corners getting rounded off

    I am using artcam pro 2008 and exporting to mach 3 to run my router. In my drawing the corners are 90 degree perfectly square. When I create a 2d profile tool path in artcam it is rounding the corners in the toolpath preview. If I select machine along vector it will square the corners but it does not compensate for the tool with and just centers the cutter along the vector. I need square corners with tool radius compensation. I have CV mode turned off in mach3 so I know that is not it.

    Did you cut anything? Compensated toolpaths will have rounded corners and still cut square cornered parts. The toolpath has corners with the same radius as the tool, so they leave a square corner.

    I cut one part with the 2d profile cutting from artcam and in mach 3 I had cv turned on but I had the check box lit up where it said "stop cv on angles > 89 degrees".

    I have dry run the machine several times and it seems to do the same thing no matter what setting I have on CV although it does come to a complete stop at the corner with it off. This is why I thought it was artcam putting it in the code.
