Z probe height
Im using ramps 1.4 with repetier firmware and host program. No matter what value I change the z probe height to it dosnt help keep from my extuder being to close to the bed to print, cause jamming in my extruder. I have changed values both in the eeprom and the configure.h file with seemly little to no results. I have made the values both positive and negative to see if it would get closer or further from the bed. From what I can tell all of my auto bed level is really innaccurate and when it does work it seems its just by luck. 1 out of ever 5+ bed levels might get me one printable z axis distance that wont jam extruder. Most of the time the extruder is just mashed in to the bed. Is there another setting that im missing? is auto bed level just that terrible? I don't understand.
from what I can tell the z probeis working. I can manually deploy it with gcode commands, and undeploy it. it does click in when iut touches print bed. If I try to auto level 2x in a row with out powering off printer first it will cause the printer to act werid, all the axis will go seperate ways and the z probe led light will flash, not really sure whats the deal with that either.

enables it and stores it in eeprom, so no need to repeat. G29 is not autoleveling, it is just measuring z as average of 3 points - at least in repetier-firmware.
Make sure the 3 points span a region that is reachable with active z probe. If you hit parts that just means the 3 points are too far outside.
If every print autolevels you must have the code either in host start gcode or in slicer start gcode. I personally do not autolevel every time. Only if I think I have moved the bed.
