...and the code continous like 50 times...

I can conclude that the stepper is gaining som extra steps everytime it shifts direction. I have tried to change a lot of settings in Mach3 to locate the problem, but nothing helps (Velocity, acceleration, kernel speed...)
Maybe it's a hardware issue, but please guide me in the right direction to whatever the problem could be.
