    Default laserworld 50k scanners - getting hot

    got some laserworld 50k scanners.

    the Y galvo is getting seriously hot, but X is just fine.

    i knocked the mirror off the Y, although ive put it back on, its vibrating a little. could this be the cause of the galvo over heating?

    Yes, when the galvos run hot the mirrors can get loose.
    Had experienced the same thing with a pair of laserworld 50K.

    Maybe you tuned it too hard.

    If your mirrors are loose and start to resonate I think the driver needs to work harder to keep the resonance under control.

    I had allready 2 loose mirrors with 50k laserworld.

    I can only advice what no to use, do not use 2 seconds quick dry glue.
    This glue can shrink and bend the mirrors.

    do NOT use crazy glue either..

    i think a simple two part glass epoxy would work fine.
