Quoted from mhkohne:Hmm. It looks OK from the front, but now that you say that, I haven't tried pulling it off to have a look. Given the general disrepair on this machine, I could certainly believe that it's not on right.
Ugh. The speaker panel on PinBot isn't slid onto brackets like later systems - it's got a couple of L brackets at the corners and it's screwed on. I had a good look at it, and it doesn't appear to be incorrect in any way.
I may have figured the problem out - there' s a couple of pieces of wood on the ceiling of backbox (near the lock). I'm now suspecting that the backglass is leaning back a bit at the top, and hitting those, making it hard to remove. I was able to get the glass in and out today no problem, so I'm not sure yet.
On the plus side, I got it working well enough that the wife could play a game. Still have to level it properly and then we'll see how it does.
