My KRMx02 build is essentially complete. There is one issue however where I know I am missing something but cannot put my finger on it.
The X and Z axes are working perfectly, but the Y axis ( with two stepper motors) is not. Mt diagnosis has shown the two motors ( and yes they are slaved) are running in opposite directions. So when I try to move the gantry either forward or backward there is nothing except noise as the two motors fight each other.
I have disconnected each motor separately and proven that the gantry runs perfectly with either motor connected. But not both.
So my question is how do I reverse the direction of one of the motors?
I have purchased the prewired electronics package from CNCROUTERPARTS.
I am using MACH 4
