You are using the same Master Code and User Code on both Vex Controllers??
So if one Controller works fine, and the other does not… That would indicate a bad Vex Controller…
Master Code being version 8 is fine for use with the Crystals.
When using Crystals, the Timers are critical in moving from Autonomous to Operator Control. Since the Timers seem “strange”, I would guess that this is the reason that the Autonomous Mode is failing…
