Yes I have a multi meter, and I'll double check the coils. I think a glasses screwdriver will get the pins out. I have a spare motor cable and will mark it as reversed. They are JST style connectors which are much used in the RC hobby for battery balance connections.

The axis reversal is self inflicted as the new X axis carriage has the belt path inverted from the OE unit.

The Titan Extruder has a different filament drive and a 3:1 gear ratio.
