Revision to Using the manual bed levelling assistant
|* You must set up a bed.g file in the usual way with at least as many probe points as adjusting screws. As a minimum, you should have one probe point close to each adjusting screw. You can have more probe points if you wish. For example, with a square bed you might choose to probe close to each corner even if you have just 3 bed levelling screws.|
|* The value of the S parameter on the final G30 command in bed.g must equal the number of adjusting screws.|
|* This facility does not work on delta printers. On a delta printer you can have auto calibration correct for bed tilt instead.|
