    Auto Leveling bed

    Hello,

    I don't have found post about auto levelling bed so I have started one.

    Anybody tryed to do it ?

    I have already bought the components.
    It come from china, so it will take a time.

    If it works I will let a tutorial.

    I do have both the components and the tutorial, but I do need time to get an adapter to adapt it to the extruder.... darn!

    hi Bolson,

    so many things to do, and not enough time to do it .

    Does your RL200 works again ?

    I have asked Ethan if we can connect servos on the board, and where exactly.
    I am waiting the answer.

    If not, i will install only the endstop and i will rotate the arm manually.

    Hi Bolson,

    I have just received the answer from Ethan : Engeeners have been looking at this but have determined the current board could not have auto leveling but the new board could if we develop it and change the structure of the printer to accommodate it.

    What a surprising answer
    By the way, I continue...

    I didn't succeed to locate where to fix the servos on the board But I have always 2 solutions use a manual arm with an endstop or use a capacitive sensor plug on a Z endstop.
    In order to be the most accurate possible, I have choose capacitive sensor, perhaps it is not the best solution... will see

    I have ordered one, I am just waiting it.
    I will report here, as soon as I make my tests.

    Thanks Bolson, with this, I have found where to connect the servos.



    Thank you very much

    As soon as I receive the components, I make it and I will do a tuto if it works.

    BTW; latest Marlin codes includes Manual Bed Leveling, which you can use without any additional hardware, though I can't try it yet.

    There, you can find a video that show autobedleveling on an extreme situation.

    The servo is to move in position and retract the Z min endstop.
    Without it, it will hurt the objet during the printing.

    With a servo and the endstop :

    A second solution with a capacitive sensor :

    The 2 solutions are cheap, less than 15 $

    An Alternative solution could be along the lines of this http://community.robo3d.com/index.ph...ke-kelly.2574/
    However im not sure if it would work with Rapide. Gets rid of all the need for seloniods and uses simple microswitches. personally I have a robo3d printer but I do not use any auto levelling. Just not worth it. Just dial in manually.
