You need to redo your motor tuning settings. You have the X axis set to a MaxVel of 100 IPM and you can't get to that speed at 25KHz. You can only get to 75IPM, so the Calcs that Mach3 was doing was based on the 100IPM and not the 75 that it can do max...

If you tune your motors you should be good to go

Im affaid thats not the problem.
everyonce in a while my computor locks up because I click on to many things at once and when I reboot it, mach for some reason revert back to 25khz. I just switch it back to 45khz and Im done with it. I must have accidently posted my xml when it was in this state. but I can assure you im running at 45khz and that isnt the problem. my computor isnt internet accesable so I have to copy file to a flash drive to post them and move them around. so that what happened there. sorry

Hi Chris,

try this modified version of your code, and let me know what happens, also have a look at the comment at the end of your code.

I have tested it here and it still looks good... Try the following and tell me if you miss steps

From X0.0 A0.0
G00 X.1 A180

and

From X0.0 A0.0
G00 X3 A.1

Do you have a problem?

Thanks
