    Default Question about Cloudray RC1001 Galvo Scanner Head

    First of all hello everyone, I was recommended to post my following question in this forum, I apologise if I'm posting this in the wrong area!

    For dabbling in SLS printing I'm considering buying the afforementioned Galvo Scanner.
    Sadly, as I'm not exactly into the laser business yet, I'm a little confused by the data given by Cloudray (as seen here: https://www.aliexpress.com/item/4000557654102.html )

    My main question is, will this galvo scanner need analog drivers like the cheaper, smaller galvo commonly found? The page mentions a 'XY2-100' digital interface aswell as board dimensions which makes it sound like the driver is integrated and it will only require a solid +-15VDC supply? The Datasheet mentions some board dimensions but considering it's not mentioned anywhere else, i'm a little uncertain, so perhaps someone with more expertise can chime in and tell me.

    Also to me the wiring diagram seems a little misleading / flat out wrong, as it looks like they recommend shorting +-15VDC to GND?

    I'd happy to provide further info if needed, otherwise thanks in advance.

    Best regards,
    Hexa

    ... XY2-100 is the digital interface type ... and the zig-zags are misleading - 3 shorts for +15V, 3 for GND/COM and 3 for -15V (ignore the connections inbetween)

    Okay, thanks for confirming my thoughts!

    One more thing - the data interface, I assume those are meant to be differential pairs? Is there any way to figure out the required voltage for them?
    I asked the manufacturer, but i'm not sure wether or not they are willing to help out with that sort of info.

    Best regards,

    ... my galvoheads have the same interface and are driven by a BeagleBoneBlack with capes supporting/driving only 5V at CMOS level, so GND to 5V signals seems to be sufficient ...
