Can Planet CNC handle workpiece rotation and is yes, what’s the workflow.

I would like to solve the following situation as an example:
My stock material is a rectangle of 200mmx300mm
In CAM the x&y 0 is set to the middle of the stock.
The GCode should put a chamfer on the edge of the stock
When putting the Material on the Bed the stock is not placed perfectly square and the Software needs to compensate for this.

In my old software this was quite easy, measuring a few points, it automatically got the correct center of the part and the rotation. In TNG I was able to find a way to measure the angle of the stock, and a way to rotate the gcode. But the gcode is always rotated on the origin of the coordinate system, not the xy0 of the gcode. Additionally I have found no way to measure the middle of the part if the part is not square.

BR,
Klaus
