Alright, this must be something very simple, but I probably am that much of a novice at this too. So here goes... I managed to come across a few galvos for damn near free! at $5 a pop, I really think something has to be wrong with them. They came complete with the mirrors which are chipped a bit but still very functional, and absolutely no identification, datasheet or anything. There were a few numbers on the galvos themselves but I couldn't identify them being the beginner I am in this field. As a matter of fact I hadn't even thought of doing a scanner until I came across these galvos now. Therefore the questions now follow... What would be the absolute easiest way to test a galvo? Or how would be the easiest way to drive a galvo temporarily? I have a USB device that converts signals to a somewhat of a high-speed RS232 port. I have previously used it to drive a stepper motor using a motor driver. Although, with galvos, they sense current change instead of voltage, right? And to control them you pretty much have to create a sine-like current wave. At least that's how I think of it. Does that make sense at all? Any beginner advice and guidance into where to look for a quick and dirty galvo test would be greatly appreciated.
Thank you;
