Help Make 1st Step - Wiring Up Drivers to Motor and Arduino

[stirling]

I have got enable unconnected, I have tried grounding it which results in the loss of holding torque.

This is what should happen. When your drive is disabled it is NOT holding (RTFM) So far so good - leave enable disconnected.

I tired this morning to hold the step wire to ground and nothing happened

This is also as it should be. If you RTFM it says steps occur on the RISING edge so holding it to GND will do nothing (except that when you remove it from GND - IF it has a pull up resistor it should step ONCE.

What is the step pulse MARK and SPACE from your Arduino? The timing sheet on page A-3 is a bit crap in that it gives the step clk width to the LOW and yet it says previously that it steps on the rising edge. Anyway if you arrange your Arduino to give a square wave of equal mark, space at around 50Hz it would be reasonable.

Make sure as well as your Arduino to driver pin6 step wire you've also connected the arduino GND also.

If that doesn't do it you may want to post your Arduino sketch for checking.
