Having sorted the knife problem I sent the image to cut and now it is saying it is not connected. I've checked the leads and they are all okay, it moves as if it is going to start then stops. I've tried switching it off and on again but still the same problem. Last time I used it (about a year ago) it worked fine and it's trying to work. I haven't updated my version of software for a while because in the past people seemed to have so many problems. I have a feeling it is something silly I am doing/not doing, any tips anyone?

The only reason I don't use this more often is because it has to sit on the floor and it is absolutely back breaking bending over to use it. It's that or getting on the floor, I simply need a bigger craft room - fat chance.
