"Port in Use" error message

[DKhast]

I've been churning out cuts for the last hour, no problem. The Robo Master crashed a couple of times and I'm not getting an error message everytime I go to cut that the USB port is in use (which it isn't). There's nothing in the print queue for the machine; I've tried restarting the computer and it's still doing the same. Any ideas?
(and I'm so sorry to keep on asking!)

Rather than restart have you tried powering down

or trying a different usb port for robo

have you checked printer queue

What ever port you use when you first install you have to always use the same one. Perhaps you should just power everything down and rest it for 5 - 10 mins then try again or your USB port could be starting to play up.

Really!? I'll have to keep that in mind. I guess I've been lucky so far and am using the same USB port by accident.

Take carem

I turned it all off, restarted and it was fine....must have been "port fatigue"!
