I pretty sure it will solve your problem. I ran into this with a Hypertherm, perhaps because I had to use Raw voltage (older Powermax 600) and ran the raw voltage and torch on/off wires out the same hole, and parallel inside the machine. Generally it’s bad practice to run your low voltage comm wires parallel and close to noisey high voltage wires. Anyway it was solved with a USB isolator.
The chokes attenuate the noise, the isolator removes the path. For anyone that wants to buy a usb isolator I provide links in the below post, you can also grab cheap ones off ebay/amazon.
