Greetings
Sounds like you put a lot of time into your TT. Good for you. Experience is the best teacher.
Is your motor the pancake type?
‘Since you have been in touch with Oracle, they are most helpful with any of your issues.
I only used the wall wart power supply for a very short period. On my MK 2 I purchased the ModSquad power supply. A good power supply makes a big difference. I no longer use the ModSquad PS. If you can get your motor working and it’s the same type that was on my MK 2, I would consider letting go of the ModSquad. I no longer have a use for it. The MK 6 uses a different motor. I purchased the Turbo PS for the MK 6.
When setting up your TT make sure everything is level.
