Auto_Bed_Leveling with positive Z_PROBE_OFFSET_FROM_EXTRUDER

[Roxy]

Hi All, Nice to see you working on this. I just got a printrbot metal simple. It's using an induction sensor for autoleveling. It's never extended or retracted as i just sits about 1 mm above the nozzle all the time. The sensor detects the metal bed about 2-3 mm above it and acts as the sole z-endstop. It was really simple to measure the offset and enter it into the firmware using M212. I'm really impressed with this little printer. I've since purchased another probe to install it on my bigger printer. I'll let you know how it goes when I get it installed.

It would be interesting to see how repeatable it is. Can you be talked into loading the M48 code and running the test?
