I must have left my machine ON after last carve a few days ago but am not sure... I removed card to load project, then went back to machine to set up to run. I can't be sure (I cycled ON/OFF switch several times when I first noticed problem) but I think I left it ON because the switch position seemed odd to me when it registered in my brain. I normally shut the machine OFF and leave the card in either the machine or the programmer for protection between uses.I'm seeing dot-matrix blocks on the readout where I should be seeing the welcome message. Machine (CX) has been running beautifully til now. Any help/advice?
