Hello RepRappers,

Yesterday I setup my LJC18A3 on my P3 Steel build onto a Geeetech GT2560 board and it detects and works fine. There is one issue however. When the printer executes G28 it goes up 5mm which is the value for Z_CLEARANCE_BETWEEN_PROBES. When I execute G28 and G29 then it does the bed leveling process and lifts the nozzle for the amount of inputted as clearance between probes and starts printing mid-air. I tried putting clearance to 0 but then it can't do auto-level properly as the probe is always triggered. At first it was risen for 10mm, then I removed the value for Z_CLEARANCE_DEPLOY_PROBE and then it lowered to 5 for Z_CLEARANCE_BETWEEN_PROBES.When it homes, the display shows Z=5 and I have to manually lower it to 0, but when I start printing it goes to 5 again. I have attached my configuration.h and configuratio_adv.h but the auto-bed leveling is disabled in these configurations (these are a backup before I setup ABL but the clearance behaviour is the same).
