I used to be able to run a G32 or G30 command that would probe all of my bed points and return the trigger heights for all of the points in the gcode console. However, the best solution I can find at the moment is probing a single bed point with a G30 S-1 which only returns one result. Seems to follow the instructions for calibrating delta printers on the Duet website.
Is the ability to multi-probe the bed no longer available? I might have read some upgrade notes along that thought process at one point.
