    Default Help identify galvos.

    Can anybody identify this set of galvos and driver card?

    Driver Card


    A view of the Galvos (a slight mishap with one of the mirrors )


    Back of a galvo


    Another shot of the back


    And finally one of the connector cables



    Cheers for any help.

    Thanks dave.

    Do you happen to have any details on the adjustments for it?

    They seem to run great with a dmx/avr controller but when I use my ilda the images are upside down/back to front/inside out etc...
    and everything is totally distorted.

    Ill pm you the details.

    What are you driving it with anyway? Have you verified the output of your laser software/interface?

    I'm using Mamba Black with the Medialas USB box.
    I only bought it about a month ago so (brand new) so I expect it is ok although I have no way of verifying this.
    Maybe I should ask one of the members in the UK if I can send it to them to test.
    I must admit it does seem a little tempermental and I sometimes have to totally reinstall Mamba Black to get it to output anything.

    What happens when you scan at a slower speed? Can you invert x and y in mamba?

    The only invert that I can see is blanking.

    Just a thought, but if you invert +x and -x, +y and -y, they you mirror everything.

    The driver card for the galvos uses a common ground for the input, ie. 0v +5v for x and 0v +5v for y rather than -2.5 +2.5v x and -2.5v +2.5v for y.
    The avr/dmx card is also 0 +5v outputs with common ground too.

    Thinking of that could that be a problem because it will meen that the -2.5v outputs of the Medialas usb will be tied together so the voltage diffderntial will be all to cock.

    Normally ILDA defines +-5V differential (so from -10V to +10V measured between the two poles) and not +-2.5V for X and Y. So perhaps you mean -5v +5v.
