Basestream is only available if port is open

[zurdoid123]

Hi again, new issue, After fixing my EMI a while back, seemingly coming from the router. I moved the cable to the opposite side from the controller and it have been working fine. I have since then ran the machine without problems. But yesterday it started making trouble again.

Iosender sops sending commands to the controller (SKR pr1.2) and after a hile it just stops moving. When I then click Stop an error comes up saying that BaseStream is only available if port is open. It seems to happen random times, no other machines running in the workshop so it cant be from their noise.

I tried yesterday finally hooking the controller up to its own PSU, instead of being powered from the USB, but no change. Still the same problem today..

I have turned off the energy saving function for the usb ports in device manager.

Any tips?
