    Just got this printer yesterday and i can't get it to print. It always starts printing in the air about half an inch off the bed. When it does the self calibration the extruder hits the plate in every stop it tests, but when it starts to print it goes up about half an inch. Whats going on?

    Open terminal and watch the results from G29 come back. Keep an eye to see if any are very off from the others. You can copy+paste the log here as well if you're worried.

    You might also need to adjust the Z offset if you haven't yet

    Actually first step would be to open a terminal and issue an M119 command and tell us the results, Likely the Z axis will show as triggered and it shouldn't be. Once we know if the switches are in the right place we can move on to any remaining issues.

    Sounds to me like the switch is working fine

    I had this happen when I got mine it turned out to be the switches were not positioned right due to shipping. If you lift the horizontal bar that the extruder sits on look at both the left and right switch, make sure they are positioned correctly then lower it back down making sure it sets properly and that the wires contacts are facing you. Then you may have to eyeball the bed and turn the left or right vertical rods together to raise or lower it. Here is a good reference for that plus you might as well start watching novice expert videos.
    He has a good video of this http://community.robo3d.com/index.p...ng-video-guides-bed-leveling-jams-clogs.5851/

    This helped me with my problem your problem/s may vary I am just sharing my experience.

    Yeah, told you Z would be TRIGGERED. one of your Z endstop switches either doesn't fully engage or it is not aligned with the X Axis Idler on one side or the other or both. Remember when troubleshooting problems always do the simplest things first, that will usually take care of the issue.

    Yeah it's pretty clear to me that your X axis is off level and so when it gets to the right side the trigger is activating early. Do a paper leveling to fix this. Just put a piece of paper down on the bed, lower the nozzle so it's just barely above it but not touching. Slide the carriage side to side, adjust the Z threaded rods by holding one side then spinning the other, repeat till level

    As Tim Cook would tell you, "Then you're not holding it right." You did the M119, it told you it was TRIGGERED, then something is wrong with the switch or both do not fully engage.

    They physically can't all be TRIGGERED in home position, because auto homing moves them away from the 0,0,0 position once it determines what HOME is.

    Waldo you're not helping. Triggered means little to nothing in the home position and since it doesn't just raise each and every time that means it's working somethings.

    Salty, did you do this?

    What my gut on this is saying that the little piece of plastic that holds the Z axis switch on the right side of the bed is either loose or somehow a hair low. The switch is not being fully engaged when the carriage moves right. The threaded coupler (the silver or brass hex part) is probably bottoming out in the cavity of the right side X-Idler arm and the switch just barely engages, you actually want the X-Idler arm to firmly rest on the switch and the threaded coupler kind of just goes for a ride along the threaded rod.

    Just for completeness I would check both sides.

    ...
    <-Bed x: 205.00 y: 230.00 z: 5.67

    Those numbers are a bit whack. Something is wrong when it did those leveling points, I can't imagine the bed is that warped.
    It sensed a false trigger.

    Can I get a picture of both of your Z endstops being sure to show the switch making contact with the carriage? Also a general picture of your X axis levelness
