Hey, today I received my Interface from you guys. Thanks for the very fast shipping! Everything works absolutely fine until my spindle is turned on. After that the device goes crazy, clicks randomly any buttons and isn't usable anymore. I use a cheap chinese 2,2kw spindle with an huanyang vfd, shielded cables and added additional grounding to the spindle. I know that there can be issues with the touch sensitive buttons and not properly shielded cables but in my case the wires should be properly shielded. Is there anything else I could try? Thanks Bastian
