I have a Dt-30 set from Dave that had been working awesome until i noticed slight wobbly images, i figured a dc ground connection came lose.
I took it apart, tightened screwed conections and soldered connections that i had connectors on, and fired it up.
SOLID frames no shakes or bearly noticeble wobbles..
3 minutes after running flawless it came back.
I drove myself mad thinking it was a ground connection that i was not making, or a scanner driver over heating or ground loop.
After attempting "different grounding schemes" thinking i wired it wrong it would make my image worse or back to the original issue.
I later isolated the +/-24v PSU, motors, and driver boards from the system and shined a beam on to the mirrors and still oscilates a few minutes after being turned on for a few minutes without anything connected to its signal inputs.
I swapped one end of each x/y cables and noticed the oscillating swapped axis so i narrowed it to the X axis board.
I am familiar with the power and signal wiring but nothing when it comes to troubleshooting or tuning boards.
I am posting this in hopes someone can steer me in the right direction to figure this problem out. I know its a long shot since this forum is way quiter than i remember and alot of old friends from here have moved on from this page/diy.
I will continue to research but i feel like I've hit a road block with this one.
Thanks for any input.
