Thanks for all your responses... I've modified the ini file to have much faster acceleration settings in the TRAJ section and it seems to help a lot. I also read up on the G64 G61 modes, haven't tried them yet, but I understand why I would use them.
Really i was testing rapid movments for foam, there's no way I could mill at 120IPM doing any kind of real material, I just did some 3d foam tests though at 120ipm (i really dont' think it was going quite that fast) It was hauling though compared to the old stepper motors, at least 8 times faster. It was quite cool.
Heres what I changed my ini file to, the TRAJ section at least:
[TRAJ]
AXES = 3
COORDINATES = X Y Z
HOME = 0 0 0
LINEAR_UNITS = 0.03937007874016
ANGULAR_UNITS = 1.0
CYCLE_TIME = 0.010
DEFAULT_VELOCITY = 0.0167
MAX_VELOCITY = 2
DEFAULT_ACCELERATION = 30
MAX_ACCELERATION = 30
PROBE_INDEX = 0
PROBE_POLARITY = 1
I had acceleration set at 4 and 4 before, I set them low just because really i didn't know what to set anything too, 30 seems a bit high, the motors can handle it, but the machine isn't quite as strong as I thought it was eheh.
Thanks for your help though, i'll obviously use G61 when I need the exact path, course when i'm milling a piece like that i'm usually running no where near 120ipm, so it isn't a problem.
Thanks,
