    Unhappy CC Error - Incremental

    I hope someone here can help. I am trying to use incremental sub-programs. However, I am getting a PLANE WRONGLY DEFINED 7628 error on line # 7665. I am trying to turn CC in a straight line. No issues in the Absolute code, but Incremental its not working.

    Any suggestions on how to correct my code to run?

    7661 LBL 6
    7662 ;FINISH ID 2
    7663 L IZ-1.8 FMAX
    7664 L IZ-0.615 F1000
    7665 L IX+0.045 RL F660 - error happens on this move
    7666 CC IX+0 IY+0.045

    7669 C DR+
    7670 CC IX-0.7125 IY+0

    RL refers to applying cutter comp left
    What radius is currently on the tool ?..it might be trying to fit a larger tool radius into a smaller corner.
    You might want to try proving off using R0

    It's quite simple. To engage tool compensation U have to make (or at least program) a move that is no shorter than tool radius. It's like U would want to paint the wall with roller, but U have to decide first which side of wall U'd like to paint so U need to stand in front of this side and push roller towards the wall.
    In following lines U start to move along arc so U need to proper define start point which actually depends on where U moved from to turn on the compensation. Both sides of cylindrical wall can be painted with the same side of touching with roller and in the same direction, so arc programmed is not obvious for CNC.

    The radius in the tool table is .0001, we commonly use WEAR type CC. so we program with the radius of the tool taken into account and only add the delta needed. Typicity is .0005-.002 is all that is needed. This allows us to use small leads in/out for the comp move needed. I ended up switching back to absolute to get these running., but still would like to use incremental in the future.

    But U need proper start point for arc anyway. Plane wrongly programmed refers to the improper arc programmed further.
