Driving me insane! I', ive calibrated my axis and it moved exactly the correct length when calibrating and sounds smooth enough, in the motor tuning section my steps are 318.8405797 and velocity is 3340.2, acceleration is 152.89773, in the Step Pulse and Dir Pulse ive got 15 as per my THC instructions

So I can jog at 100% which I'm assuming is the 3340 mmpm without any problems at all, in the simple gcode square box (attached) i'm running at 3200 and it stalls all of the time in the x dir, they Y its fine

There is a good chance Ive not got my stepper drivers DM542T set correctly for the nema 23 motors I bought from stepperonline could this cause the issue I'm having?  Cheers

Here is the square box ive been trying to use
