Just passing this along to anyone having cube issues (not spinning fast enough).
Little background: When watching vids I noted how slow some of the cubes are to respond especially with the added weight of a mod cube .
I received my Pro and it had a mod'd Tesseract on it (not mine) and it was horrible. Clunky -squeaky and just not fun to hit or watch. Test spinning it I noticed it was off center and the top point spun more like an egg....that must be the issue right?
So I took it off added mine and it was a little better, spun true, but not great speed and that pesky squeak didn't go away. After eyeballing it a few times I took out the unit lubed the shaft with 1 lube and from that point I could see the issue.
On two Avengers pins one LE and one Pro I have found that the metal disc that the opto reads sits too high on the shaft causing it to rub the opto or in this case squeak from contact. If the cube is off center it will cause a slight wobble which makes the slow spin or noise even worse.
With a quick turn of the allen wrench I dropped the metal disc on the shaft to be centered in the U shape opto.
Now with the extra clearance and a quick tweak to the Tesseract bracket, it spins like a top. There is a height adjuster screw on the bracket and I lubed that area with the 1 lube also.
The Tesseract is now my second favorite shot on Avengers - second only to the Black widow shot.
Really love this game in Pro form.
Hooked on Pinball.
