DT40 wide help.

Yet, for testing purposes, that's exactly what I've been told to do to determine if a galvo motor is bad.... but, I can see that you might not want to leave it that way for any length of time.

Provided the image is simple (e.g. a circle) and small, this should not be too big a deal. If one amp has to be so differently tuned that it would cause damage to the other, then there's something wrong there IMHO. I think this is a useful elimination check, but in general use, the amp and galvos should be matched.

Well all I did was just a test ,put the ilda test pattern, it squealed like pig for a couple of seconds, then before I could turn it off the coil had destroyed itself, then again they where very cheap scanners, I should think the dt,s should cope ok
I guess I should not have used that test pattern and went with I simple square

I wouldn't do a swap amp test with any image that has corners. Smooth sine/cosine based images like a circle are much gentler.

Come to think of it, I think the only thing I was looking to see is that the mirror snapped to the home position when the projector was turned on and, I didn't need to try to display an image.

does anyone actually have a manual for dt40w's? the set i'm using didn't come with any documentation.
