G-Code ripper can read a g-code file, add probing points and export a new g-code file that will adjust the input g-code based on the probed data. Tool paths heights between probe points are estimated using bilinear interpolation. This video contains c couple of examples applications of using the G-Code Ripper auto probing function.
