Autofocus on GCC Laserpro C180 not functioning

[John Levinson]

So on my GCC Laserpro C180, the autofocus no longer works. When I hit the A/F button The bed will move down, but not move back up. I've replaced the autofocus pin as well as the pink cable that runs to it, and it's still not working.

Hey John: To be clear, the bed moves down (away from the lens) when you hit the AF button? If so, the contact might be stuck or needs adjusted.

I'm not sure how the autofocus microswitch works on your machine, but it's likely the problem-

I have my LS900 autofocus disabled most times, the plunger extension is usually in the way (I use steel bars as weights which are taller than the plunger). But the switch post is still there. If the switch post gets pushed up for some reason, it will stay there and the focus switch will remain closed, and when that's the case, I get the same action you're getting.
