Generated G code in Fusion 360, and used Repetier Host to run the MPCNC. At the very end of the milling, the bit plunges straight down into the material, instead of lifting up out of the piece. Where should I start when looking for a culprit? The G code doesn’t appear to have any erroneous Z coordinates that indicate a downward plunge.
Here is a video of what we see just before it happens. The Z axis maxes out at - 9 for some reason, even though the tool travel is not maxed out. It registers changes in X and Y, but Z becomes useless. It then plunges down into the work piece, but the travel depth is not registered because it’s maxed at - 9 on the readout.
