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

[Ross77]

I would try connecting enable pin 11 to high as I beleive that leaving floating can cause it to be unstable, especially if you haven't got all the grounds connected in star. at least if you make it high then the drive will be enabled and you can cross it off the list.


Have you got a logic probe? these are good for testing logic status and detecting floating and ground issues

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.

Ok pulse it with 5v then. If it doesn't work by pulsing the step pin I doubt that it is the Arduino, would indicate a motor/ driver issue. Have you got any other motor or drives, would help establish if it is a hardware/wiring problem or software.
