    Im new to CNC, playing with China engraver.
    Using Sketchup V8 and V16 with version 1.4d sketchucam.
    Have test file that puts gcode out for 2 levels of cut. Cuts a plain bax, moves to a pocket and tries to cut at wrong Z. Have tried many different options but all come out the same.
    Il try and post code I get.
    Newbe, so probably a simple thing Im doing wrong.
    Thanks in advance.

    the answer is right there in the code (-:
    Code:

    the Y moves...
    You have set your material size to be smaller than the cut, or positioned the 'safe area' such that part of what you want to cut it outside the safe area.

    The Z limit: you have set the Z_MIN and Z_MAX incorrectly.
    The answer is here http://swarfer.github.io/sketchucam/afterinstall.html

    Also, watch these videos to get you started using SketchUcam...
