Running Stepper Motors

[tmd019]

I am having problems with one of my motors. I toggle the motor in a positive direction at different intervals. The motor will turn the correct direction during the first few intervals and then the motor will start going the other direction for an interval. I am using Mach3 and in the process of learning this program and setting up the CNC machine. My other two motors are running fine. Is there a problem with the motor or a Mach3 setting??Is there a Mach3 forum?

Im using stepper motors.

i would check the step/direction wires,make sure they are not backwards
if the other two motors work fine,check the setttings for them see if something is different on the problem one,maybe a setting is wrong,just a place to start

i will bet it the step and direction wires are backwards
