I have to admit I don't have a vast amount of experience of the internals of EMC but it shouldn't be difficult to probe the whole sheet then generate a correction matrix that is used before the G-code is generated. Probing a large sheet would be very time consuming. Do you need this for

One possible solution to the probing issue is to write a special kinematics that interfaces with probing. With the kinematics turned off, probe the sheet at the desired resolution. A special (new) command would write the X, Y, Z coordinates of each probed point to the kinematics. When the
