Thanks a lot actually the other profile was just testing on my bedroom computer.

Thanks Hood, The problem is mechanical vibration in one of the limit switches. I felt a lot of vibration in the Y axis switch and loosened the screw holding it in place and the problem went away. I tried a debounce interval of up to 3000 and it still tripped. I am going to have to find a way to isolate the vibration from the router.
One other problem I noticed is that the machine's soft limits have moved. About have way through the roadrunner program the tool path seems to have shifted about an inch. Could this also be associated with the mechanical vibration or could it be from electrical noise.

Two things it could be, one is electrical noise the other vibration. Both of these could be making Mach see a limit switch input. Mach is fast and you may not even see the LED on the diagnostics screen light as its too fast to show.I am having the same problem but I don
Best course of action is to make sure your limits and Stop wiring is properly shielded and grounded but you can also set a debounce interval on the General Config page. That will make Mach ignore signals unless the persist for longer than the time set, try 2000 to see if it helps.
As said however it is best to properly shield and ground wires rather than using software to mask the problem.
