Is there anything different in how this version applies bed correction after g29? I notice it generates and outputs a bed compensation matrix. Is it adjusting the bed by applying a plane to the z values or is it adjusting different areas of the bed by differing amounts ie compensating for a truly uneven bed?
The reason I ask is that this is how bed levelling is handled in Rich Cattell's marlin fork for deltas and it improves first layers immensely. We all think our print beds are flat but this is not often true.
If it does use this method then there is every reason to use many more than 9 points when probing.
