Just some Y carriage component documenting here.
Verification of Y slides
Verification of Z slides
One thing to note, I did orient my bearings in the + configuration meaning, I turned my bearings so that the rollers were at N, S, E, W, and then scribed north on the case of the bearing with a pencil. When attaching the carriage with zip ties, I made sure that North was oriented up on all three bearings so the Y carriage rests on the bearings internal components.
Nothing is random in the wiring of the Prusa. The cable placement is VERY deliberate.
The extruder power cables are deliberately wired in this fashion.
I deliberately wired the pinda so that the fan power supply was behind it.
