Just unpacked mine. Moat doesn't recognize the ball (switch 36). The switch triggers if I break the opto signal with a pencil though.
Do you have any idea what I could do to adjust the opto switch ?

For a mysterious reason I cannot yet understand, when the ball is sitting on the black bracket, it is not clipping the opto (weird).
But 1/8" higher, it works.

I just added a teeny-tiny slice of foam on the rubber gromet below to raise the plunger so that the ball is raised a bit.
Problem solved with a little temporary hack, so I can play tonight.
Will investigate later.

Has anyone switched the flipper bats to red rubber? I have so much more ball control now!

Has anyone else noticed how the different shades of the display are too bright on MMr ?
The 3 levels are almost the same brightness thus the DMD appears to be only 1-bit two colors (your color selection + black).

When you go in the special CGC menu, you see a square on the right ? It's supposed to show the 3 different shades.

I tried to fix the problem using the LCD controls (brightness and contrast).
I somewhat managed to fix the problem but the overall brightness of the display is much lower than I would like.

I'm happy to report that the contrast issue with the display (https://pinside.com/pinball/forum/topic/mmr-owners-club-all-things-mmr-discussed/page/7#post-2918117) is fixed by the new firmware revision.

Looks tons better.
