Whenever I put in a Z offset during M851 during set up, it's giving me a positive result on the print bed (moving the bed further away from the nozzle). Any advice is appreciated.
Doesn't a negative z value mean the probe is lower than the nozzle?
My offset is negative, and yes when the BL touch is probing it is below the nozzle but when done it retracts the pin so its above the nozzle.
That is true. I don't have one so forgot about the pin ejection.
