X-carve loses connection when switching electric machines

Hi everyone, if got the Problem, that easel loses connection with the x-carve controller (the button turns blue) when I switch my any eletric machine on the same eletric power phase. Thats big problem because if got some 3phase machines like for example my dustcollector, so i cant just switch to a not used phase. UGS is doing the same. Im running my xcarvve with a compaq laptop, but the problem still occurs when the latop is unplugged.
Sry for the bad english, I’m from Germany so the XCarve is running on 230V

I have the same problem. I got a powered USB hub and that fixed it for me.
