You cannot start a contour with a G24 block.
A chamfer is possible only in the working plane.
The corner point is cut off by the chamfer and is not part
of the contour.
A feed rate programmed in the CHF block is effective only
in that block. After the G24 block, the previous feed rate
becomes effective again.
