Help needed to get started with TB6600 stepper driver

I have followed the directions here https://www.dfrobot.com/wiki/index.php/ ... U:_DRI0043 but can't seem to get the motor to budge. I am using a raspberry PI 3 with Windows IoT and believe I have everything hooked up correctly. My question is on the control signals. Is there a way to "hot wire" these connections to test out the motor/driver setup? The diagram has the PUL- hooked to the signal pin on the Arduino, with the PUL+ hooked to +5v on the Arduino.

I know the motor is getting power and assume that ENA is high as the motor won't spin when under power. If I plug in the external +12v power supply, the motor wont spin if you try with your fingers. I believe this is the correct behavior but again would appreciate any comments.

Thanks.

Thanks again. tom

2018-07-28 01:12:08 I think there may be an answer in the GPIO pins on the Pi only put out 3.3v and I think the controller needs 5v. Is that correct? tom

2018-07-27 23:54:17 One question I have is, since I am using an external power supply for the motor hookup, do I need to combine the ground from the Raspberry Pi with the ground on the 12v power supply?

Thanks again. tom
