B4R Question WeMos D1 WiFi uno based ESP8266 & rAdafruitMotorShield (V2) library

Anyone have any experience with the two? I believe the shield will need to be configured for 3.3v operation, but is the library itself compatible?

Have run into an issue. When trying the two examples from HERE I can run the DC motor example fine, but the Motor Stepper example fails with:

3fffffc0:  feefeffe feefeffe 3ffe8520 40100739 

I can call the below from a timer and it works.
stepper.Step(50, stepper.DIR_FORWARD, stepper.STYLE_MICROSTEP)

But if I try to call the below it will fail with the same error as above.
stepper.Step(900, stepper.DIR_FORWARD, stepper.STYLE_MICROSTEP)

Anyone have any ideas?
