I bought some of the 20K scanners (with DMX board) on ebay and the galvos shipped unmounted to the block.
What's the correct procedure for mounting/aligning them? Can you rotate them in the block when they are in powered on?
Also they seem much noiser than the DT40s I own - is this normal?
[At one point I could swear I saw smoke coming out of the 'X']
I've contacted the seller, but not heard back from him yet - I was wondering what the best course of action is...?

Update:
The X galvo has settled down a bit - it's still 'singing' but not as loud. Images appear to have some kind of oscillation in X as you can see from the figure 8 display.
