    Unhappy how to calibrate the articulated head on a flow waterjet

    does any one here have a flow waterjet with an articulated head?
    I am trying to see what are the steps to calibrate the A and B motors
    how do I check to make sure it is line up at 90 degrees so it can cut right?
    any help would be appreciated
    thank you

    Well, one more question, do you have spacer/ sleeve in your mixing tube assembly?

    Yea there’s a sleeve.
    So the way it is
    Is basically a mixing tube then I put the sleeve then
    I just insert the nut with the collect and make sure it’s all the way up
    And just tighten the nut and that’s it.

    Bare with I am new to this
    Thank you

    Perfect, same setup as mine.
    First you will need dial indicator in good shape, more precise - better, with some way to mount it on a tank ( I use heavy piece of steel with adjustable magnetic base for indicator).
    Home your Z,A,B, axis, remove splash shield and setup your mixing tube without a spacer (let it stick out). Set indicator on a bottom part of your mixing tube, 180° to axis of A or B motor.
    Next, on your control set FlowCUT in "Run machine" mode, on a top bar pick "Setup"->"Dynamic Waterjet"->"Straightness adjustment":

    Attachment 410864

    It will open new window:

    Attachment 410862

    Now, blue arrows next to "Height" will move your head up or down.
    Set indicator for a "0" in a top head position, move a head down and input indicator readout for a bottom for a specific motor, apply.
    Rinse an repeat until is straight, move to second motor (Let say you started with A, move to B).
    After you set second one, come back and verify if first is still straight.
    If not make correction and check second one again.
    When you finished, click OK, head will home itself.
    That is all. I hope that will solve your problem.

    Thank you
    I shall try that out and hopefully that's the problem.

    how often do you calibrate your tip?

    is it everytime you change you tip?

    thank you:cheers:

    Well, if you are not sure about machine, yes you can do it every time you change mixing tube, but if machine is Ok, it will hold calibration, unless you crash your head.
    In that situation, you'll have to check it, even if mixing tube survive (use brand new mixing tube for calibration).

    Question you mentioned out of round .010, question is it the same when you aren't using the dynamic option....

    Dynamic is for straightness of the material bevel.

    Try running that same circle without dynamic, if you are still out you might be looking comping the screw resolution.

    Re: how to calibrate the articulated head on a flow waterjet

    The screw resolution ?
    What do you mean by that and how do I do that?
    Actually when I cut small holes is when you notice it more this hose look like lemons .

    Forgot to mention is A axis left to right or front to back ? That's for when I line it up.
    Thank you

    After you have loaded your drawing to be ran, you have the option you can turn dynamic on or off.....

    Run your program both ways and check your results.

    Also what's the thickness of material that you are cutting, Dynamic should not be used on thin material, the system tries to make to many adjustments far too quick.

    Haven’t try not using the dynamic
    But I will that shot

    So how often do you guys change the mixing tube?
