Rugged USB Isolation That Simply Works

Where can I get one?

*Can protect against USB Killer?*

Looking for something like this that's industrial so I can isolate my USB from EMI while my CNC runs. My spindle is giving me issues now that my system is around 6.5 amps at full tilt.

did you solve the problem, first I had a problem with the shielded cable for the spindle and I learned that it has to be grounded at the spindle end as well so that solved 1 problem now I have usb issue that when the spindle runs it interferes with my axis controller when connected to the pc

@ale318ti I shielded my spindle wires. ( only like half way though so I made a new emi sheild that was proper length. ) Also I had some 12v lines for my stop start and hold buttons that ran through some relays that trigger auto shutdown when the drivers error out. The wires were a jumbled mess around the spindle area. I looked at my opto isolation board amd the leds were dimly lighting up at full power on my spindle. Realized it was attacking the 12v lines that are attached to the buttons and relay circuit. It's nit fixed yet, I've just identified rhe issue. I've been busy with school and work.

@@RoboArc well you found the problem thats the main thing I've solved my problem with two usb isolators one was not enough, optocoupler for the limit switches is a good idea when i have the time
