Just upgraded my Anet A8 with Marlin 2.0.5 to get auto bed leveling. The Marlin upgrade was painless, but I can't get my auto bed leveling to zero the Z axis. I go through the Z offset setup and zero everything out. But when I hit the home all key, the Z axis shows +0.6 mm or so. And the nozzle IS 0.6 mm off the bed! So, it appears to be calibrated correctly. Just won't start at 0 for the Z axis. I am using the SN04-N sensor. Everything else looks good, but I can't print in thin air. I need Z to be 0.
