General Mach Discussion / Re: Acceleration problem

HI, i have a suggestion. I am not sure if it will work but you might want to play with it any way. I also suspect that 8000 mm per is just to fast for the power of your steppers, not a mach problem just a machine limit.
Go to the settings screen and under angular limit change the angle to say, 30 and enter a speed that works ok like, 3000mm-s.
The way i think this works( art or Brian please correct me) is when the look ahead sees a direction change coming up it slows down the output to something that your machine can handle based on what you set in the field. So for a corner if your machine chokes at 8000mm per on a 90' corner than you can tell mach to slow down on any angle > (whatever you set) and go to a alternate feed rate.
To the best of my experimentation this is how it works.
My guess it is in the program to compensate for machines that are faster on single axis moves than coordinated moves. ??
