Hey Gil,

I already gave you the answer here:

> **The QCW frame is not where the workarea of the machine is.** While at the front you have the milling motor (router or spindle) and also the dust boot **protruding the QCW frame beyond the front edge of the frame** , where there is no wasteboard but only air, there is a portion at the rear of the QCW frame **that the bit will never be able to access.** You can make your wasteboard slats much shorter in the rear for this reason. You will not be able to surface this region when you want to surface the wasteboard.

This means that you have a g-code program loaded that would mill outside the workspace of the machine (outside the limits). Either you adjust the size of your 3D model so that it fits the workspace of 816 × 816 × 133 mm (165 mm for Z-20), or you set the workpiece zero (by probing or manually setting it) at a position so that the 3D model does not exceed the limits of the machine.

Since your 3D model is 527 cm × 449 cm wide, which is smaller than the X and Y dimensions of the Woodworker machine so should fit, I suggest to assume that you’ve set your zero coordinate on the real workpiece center at the wrong position, as the 3D model seems to exceed the workspace limits (=does not match the real workpiece’s position)

The _workpiece zero_ **you probe or set manually on the real workpiece** has always to be at the same position as the workpiece zero (workpiece “origin”) in your 3D model.
