auto reset problem in Mach3

[kievari]

Hi,
During work the machine automatically stops the same way as if I pressed the emergency stop button on the control box!

This happens many times during work and I can't figure it out why it is. Before, I have this problem if I connected the probe wire to my breakout board, then run the spindle (then the machine automatically was stopped working and I've had to press the reset button in mach3).

If I did the probing without running the spindle, no problem of like happened. Is the breakout board getting a problem?

What troubleshooting process I have to perform please?

You have noise triggering your estop or limit switches.

Thanks, what should I do? to isolate control box from machine plate? (they are currently on 1 table), or known better methods exist?
