My scanners displaying test pattern

Just break the glue with the screwdriver when you start turning. The pot might jump a little bit, but a 1/8 turn isn't going to kill you.

LF damping is mildly sensitive, and HF damping is moderately sensitive, but even 1/4 of a turn isn't going to cause serious problems if it slips. You may not even see 1/4 of a turn on LF damping unless you're looking for it. (You'll see it on the HF damping though.)

Andy: You've still got overshoots on your Y amp. Add some LF damping.

awesome, I'll set up my projector tonight (it was down to show some friends at work) and start tuning... I am sure I will have a few questions... and I am sure (but still knocking on wood) that one of the questions I have isn't how much a replacement would cost!

yes better but the circle is not round and you still have the Y axis overshoots marked red
the blue marked corners also look a little off but its hard to tell with the burn of the camera and the matching corners of the outer square look ok - if you have manual control of the camera try a quicker shutter speed, tho not too quick or you wont catch the whole scan.

Also it can really help if you turn some more lights on in the room, that way the laser wont over expose the camera so quick.
