Is there anything else running on that computer? Was it optimized for Mach3? When I had problems like that, it turned out to be Windows Update, which interrupts everything to call home when it feels neglected.
My equipment consist of Grizzly 6x26 knee mill that was converted to CNC several years ago using Mach3 with 3 Nema 34 3.5 amp motors controlled by Gecko G540 running on a 48 volt transformer. Everything was working for years sometimes hours at a time cutting complex parts.
Lately it has started acting up on me and by that I mean it will be moving along and all of a sudden it stops randomly, at least one of the motors stops turning.
I can continue to jog but I have lost position and I have to start over. Things I have checked:
Gibs readjusted and both X and Y slide freely, I thought it might be binding up but it never stops at the same place
Installed all new shielded motor cables with a 3.5K resistor on each connector
New shielded cable on each of the Home switches
Operating on Windows7 with nothing else that I know of running, screen savers etc.
Running at 25000 htz
Motors tuned for a conservative speed, Velocity of 30 and Acceleration of 5 but nothing that I change seems to make a difference.
It seems like it is getting a stray signal from somewhere that's causing a momentary hiccup that's driving me crazy.
I am stumped and don't know what else to change or look for
I am open to any and all ideas
Thanks
Jack

Years ago there was a list of things that could/should be turned off in windows but I haven't been able to find it. I did remove the latest security update but maybe I let one slip past me.
This computer is not connected to the internet I had it connected to be able to try Fusion 360 but decided it was to difficult for me to learn so I got rid of it.

Thanks for the Help
This morning I went into Windows 7 and removed all of the security updates that had been installed. This computer which is only used to operate the CNC Mill is never connected to the internet, so I
don't think that I need them anyway.
I also turned OFF any items that weren't absolutely necessary for Win7 to function and now it seems to be working like it used to.
I have had it running for several hours now, and so far not one hiccup or stall or stoppage of the motors.
Time will tell if I fixed it, Thanks for the help!
