Sounds like you are having issues with the pulsing.
Close Mach3 and then browse to the Mach3 folder on your drive and look for the Drivertest.exe. Double click it and let it run, if the graph has spikes in it then you definitely have pulsing issues. There are steps you can take to try and make it better, you will find them here.
