    Unhappy

    Damn... if I only had a spare grand... I'd love those scanners. You need any computer parts? I seem to have several extras of several items.
    Love, peace, and grease,

    sorry all that, my house is a computer surplus store practically. Adam will agree. Heck, while I am selling stuff, got an Lenovo Thinkpad Z61t Core 2 Duo laptop with dvdrw 80gig hd and 3gig ram with built in wifi I will sell for $500

    Closing on my house next friday, must sell these or borrow money from a friend

    You will find most scanners will run off either 5 or 10v differential. Its just a matter of setting input scale correctly.

    My controllers are +-10v. I can scale the image to 50% but what if I accidentally put full scale. Whats gonna happened to the galvo driver. Or there is a way to adjust drivers themselves to accept -+10V.

    Sorry question mark button is gone on my keyboard.

    Cool

    I'm pretty sure the DT-40 galvo's come with a dual-potentiometer (ganged on a single shaft) that is used to adjust the gain of the input signal. Why not use the same principle here? Put a 20K pot (OK, two of them - one for x and one for y) in line with the input to your scan amps and you should be able to knock the voltage down to the appropriate range.

    Also, I thought only the really old galvo amps could accept the +/- 10 volt differential inputs (like the old open loop / accelerator 124 amps and stuff).?.

    Sorry, i was meaning - adjust the input scale on the scan amps for 10v. Most scan amps will be fine with this.
