Because at that stage the firmware is figuring out what the plane of the bed looks like. What this means is that you only need to probe the bed initially and then you can store it so all that is needed in your starting code is G28 then M420 S1 to recall the mesh data from EEPROM. Alternatively, the bed can also be probed some other time (while not printing), the mesh stored in the EEPROM and then restored with M420 S1 at the start of a print. Upgrade your Next Level Wheel Stand to the GTultimate Racing or Flight Simulator Cockpit with the following accessories GTultimate seat add on to turn the wheelstand into a full Racing Simulator. THE “mesh bed level” Z correction happens by probing for offsets before print, which is why you can’t print on a Prusa without performing pre-flight to set the nozzle to sensor offset. three-point-leveling.
