    G code limitations on tool radius compensatrion - any solutions?

    Hi,

    I'm faced limitation of Kmotion Gcode interpreter which is inherited from NIST RS274NGC when using toll radius compensation - it does not allow conacave corners.
    Is there any solution how to force it round this corner what ever the tool radius is istead of just fail and abort gcode?
    Otherwise - any ideas how and where is best to implement it?

    Hi funding33,

    KMotionCNC doesn't allow impossible paths.

    Rounding the corner properly would require looking ahead one or possibly many segments and in some cases becomes ambiguous.

    The code is located in rs274ngc.cpp. Search for:

    NCE_CONCAVE_CORNER_WITH_CUTTER_RADIUS_COMP

    Regards
