    Hi,

    Recently I have build my first CNC based on Sphinx.
    For the controller I use Gecko G540. CAD software use Aspire, and MACH3 to run the G-Code

    I have strange result for my pocket operation.
    When I make pocket toolpath frrom aspire, for example i make 20mm pocket, the result is 19mm. When I try to make 10mm pocket, the result is 9mm. Any size I want to make, the result is 1mm smaller in X and Y.

    But when I make profile toolpath, the result is right. 20mm profile, will cut 20mm. Also for other size.

    Need a lot of advice here.

    Regards,

    I'm not familiar with Aspire but I can tell you that the problem is with Aspire. It is possible that you have a setting that makes it smaller, like maybe it's only the rough cut and it expect a final, finish cut, which is many times 0.5mm (which is 1mm in total).

    hi, for cutting (profile toolpath), it has no problem. the size is right. but when doing pocket toolpath, it have the problem. and aspire doesn't use rough cut & finish cut except for 3d object. for 2d pocket toolpath, it doesn't use rough cut & finish cut

    here is the gcode from the aspire
