![]() ![]() I could post one or two of the codes I tried but again they are just standard test codes you'd find on any site. If anyone has any clue what the problem is please let me know. There is an Enable (ENA) pin which I have tried connected to power, ground, and completely open to no effect. All appears to be in order but the motor will not turn, but I know SOMETHING is happening because it is getting warm. I used a voltmeter to check the terminals and it seems everything up until the driver is working properly (There is a pulse wave going from the arduino to the driver). I tried various codes that have been posted on here or other sites, and yet the motor doesn't turn. ![]() I have made all connections as outlined in the schematic and online sources. I am using a 24V 3A power supply connected to the driver, which is connected to an Arduino Uno. To drive the motor we ordered the SainSmart CNC Microstepping Driver To this end we have decided to use a NEMA 23 1.9Nm Stepper motor. I work in a lab and we are trying to create a test fixture that will rotate a solid disk through a jet flame and water bath at various speeds. And in a nutshell I have a stepper motor that doesn't seem to move. I'll just start off by saying I am new here and fairly unreliable as a programmer. ![]()
