Looking closer on the X, Y, Z and E ports i observe that the ports are labeled different on the two cards.
Old SKR v1.4: Square pin = 1B, next pin = 1A, next = 2A, and last is 2B. Also the order is EN | STOP | DIR
New SKR MINI: Square pin = 2B, next pin = 1B, next = 1A, and last is 2A. The order looks like EN | STOP | DIR
Should i rearrange the wires in the JST so that the wire that on the old card was connected to 1B, also is connected to 1B on the new card, and so on?
The EN | STOP | DIR part is in the same direction in the pinouts, even the whole connector is upside-down on the SKR MINI. Why is this? Is this just labeling the round pins?
Arrghh, I have so many noob questions..
