here is the documentation from cnc4pc explaining how to keep the grounds isolated

one more thing, the power to the speed controller must NOT share common ground to keep all things isolated

one possibility is the VFD. The VFD produces a lot of  electrical noise, you may need to have a reactor and an EMI filter. all VFD mfg's recommend them. Also check the power supply for the speed controller it should be regulated.

General Mach Discussion / config plugins will not save

config plugins will not save when I "X" an item such as shuttlepro plug in as I do not have the shuttlepro and would like to prevent it from showing up in status
when the program starts. I have clicked save settings and tried save layout-no luck, Any help would be appreciated

My concern was not with machine accuracy, but with program accuracy, and I needed to prove it to myself. I wanted to make sure that if I cut a gear that I do not increment and accumulate on a rounded number. the spline and gear wizard creates code that adds 1 rounded increment to the correct absolute value each move. Therefor every tooth cut will have the same nano error instead of progressively increasing to the last tooth cut. This is correct way to calculate each move. Program accuracy and machine accuracies are factors in the final finished parts accuracy. So now I know what mach3 is doing this gives me insight as to how to write good code.

mach 3 will round pulses up. I also had the same problem in my head. here is how I figured it out.
first I set my 4th axis to 1 pulse in motor tuning then I used the "cut spline or gear" wizard and selected gear then set number of teeth to 32  and posted the g code, zero the 4th axis and run now you can see how mach 3 handles fractions of pulses. 11.25 rounds to 11 and 22.5 rounds to 23 and so on. But if you use this wizard it will continually correct it self and not add the rounded increments by use of G90 in the code it produces.
