Thank you for all the advice. My question now is how do you control the speed of the loop iterations? My code right now will outputs a pulse every other iteration. However, I can't seem to increase the speed to what I need. I know I can use the "wait till next millisecond multiples" function to slow down the speed, however, I can't seem to increase it to beyone 1kHz.

QUOTE I was looking around and came up with a way to generate a pulse by constructing a trigger digital waveform, then putting it in an array and feeling each elements into the output. I also used the wait timer to control the speed of the loop counter. However, when I actually connected the output to the driver & motor, it doesn't really work the way I expected. The motor moves, but at a very slow speed. I have tested the motor driver by inputting a signal from an analog function generator, and it seems to work fine. Am I doing anything wrong here? PS. The direction of the motor is controlled by a constant 1 or 0 input, so that part is pretty easy. I've attached a screenshot of my program here. Thank you.

Hi, I am a student currently working on my senior capstone project. As a novice at LabView, I would like to create a LabView program to drive a stepper motor. However, I am having trouble generating a pulse train in order to drive the motor. As a reference, I am using the Geckodrive G210 motor drive, which requires a pulse train (square waves) or TTL signal to drive the stepper. More specifically, I need to output a digital pulse train at a specified frequency. Is there a simple way to do this? Thank you in advance, any help would be greatly appreciated. Panithan
