i have 4 viper 95 drives. 2 for the y axis, that are slaved. 1 for x, 1 for z.
I'm using mach3, with a simple BOB to drive the drives
i'm running a program that does a large pocket (20" x 10" x .6"). I'm stepping down by .09" in z each time. I'm stepping over in x, y by .375"
At each Z increment point, you can see that the X axis is getting off by approx .008" in the positive direction.
The Y axis however is dead on.
What are some possibilities? All drives have the same parameters, rapid speeds and acceleration.
For the moment, i'm resetting my x position from the limit switch on each step. Thats fine for now, but i'd like to find a better solution
I'm using single ended US digital encoders, but I would suspect more error if it was due to noise.
