Hmm, that's interesting. So, what happens when you disconnect the FB3 from the computer with the scanners on? How about if you disconnect ILDA pin 1, 2, 14 and 15 with the scanners on?

I just put up another video. when i disconnect the pangolin with the scanners making noise like on the video they just stop…

do you have an oscope? it might be telling to look at the output of your fb3.

the galvos should make a single tick as they jump into position when power is applied and then they should be totally stationary and quiet until they get a single from the DAC.

nope sorry wish i had one lol

okay so i figured this out
if I turn the power on with no x/y signal cabled attached to the galvos they snap to what looks like a normal position
if I turn them on with the x only connected it does as mentioned above
if I turn them on with the y only connected it moves them to where they are perpendicular to each other
if I have x connected and on then plug y in they start clattering
if I have y connected and on then plug x in they stay in the perpendicular position

please confirm you are using pins 1,14 (x+/x-), and pins 2,15 (y+/y-) on the fb3 db25 connector. it's ok to unplug everything else for testing.

I just wired in up to a breadboard and I seem to have fixed that problem. but when I have an image projected at only 3 percent it's just gibberish on the wall. you can very faintly tell what the image is suppost to be but it is way out of proportion and streched out...
Thanks

great. scan your image and slowly increase the size of the projection. with those dt40w's, 50% image size should be plenty big.

I've tried scanning the image from 0 to 50 percent it seems the smaller it is around 25 percent the scanners start clattering ouder but the closer you get to 50 it seems the better the image but if you go larger then the image is just gibberish

Heres the video.. I wouldn't let me upload an image so i have to post a video link
