Hi! I have a NextEngine 3D scanner, which comes with an accessory turntable that's about six inches in length and width and is powered by an RJ22 cable that runs from the scanner to the turntable. (The kind of cable that runs between the phone and the handset on a regular landline phone.) I'm assuming, since there is no separate power supply to the turntable and there is no way to replace batteries, that the cable simply powers a motor that turns the turntable, that the motor is a 4-lead motor, and that they just stuck the leads into an RJ-22 connector so it could be powered by the scanner. Each time the scanner completes a scan, it sends a signal to the turntable to turn a certain number of degrees so it can scan the next side.
Anyway, I want to make the scanner move around the object instead of using the turntable. So I'm building a little "car" to put the scanner on, with the axles angled so it runs in a circle, and powering a little motor on it by the same kind of cable as the turntable. But I don't know what I need to know about the wiring. I can't find any info at all on how the turntable is built and I want it to stay in one piece so I'm trying to avoid busting it open. The only electrical information I can find on the scanner is a little box that says 1 amp, but I have no idea if that's coming into the scanner or going out to the turntable. Any recommendations on what kind of motor to get? AC? DC? Stepper? Servo? Voltage? I have no idea.
