Wondering why re:3D chose to wire up the Z and Y steppers in parallel to a single driver chip each. Was this for wiring simplicity?

Matthew Fiedler At the time the constraint was the number of available motor driver channels on the Azteeg X3.
Stay tuned for more updates as we have been piloting the X3 Pro board on a number of machines and find the benefit of having more motor driver channels allows us to dedicate one motor driver to each motor.
The X3 Pro will be a drop-in replacement for most all Gigabots once we release the upgrade kit.

Manmeet I get the reasoning for pairing the connections due to limited driver ports but wondering the decision to do this wiring in a parallel configuration vs a series one was something inherent to the steppers the gigabot uses.
Additionally Was the prime driver for choosing the x3 pro over the Azteeg x5 mini the desire to have dual extruders?

Matthew Fiedler The decision to wire the two steppers in parallel with each other is based upon the benefits of having both motors receive 24V. I assume you were not referring to wiring each motor's poles in series or parallel but rather wiring both motors in parallel with each other.
With respect to the X5 vs the X3 I see them both being capable boards. The motor drivers on the X5 at the time he first released were integrated onto the board and rated at 2A. V3 now had modular motor drivers but still only four channels. Stay tuned for the release of an even more capable board in the near future.
