Good afternoon all, I purchased my EH721 plotter in July last year and its been working fine, However yesterday i powered on the machine and its now causing the electrics to trip out, Sometime it can stay on but 9/10 it will trip the electrics. I have tried replacing the power cable as may have become damaged but nothing has changed. Could this be the fuse even tho sometimes the machine stays on? Any ideas on this please. Many thanks
