I was running the machine and it ran the m50 at the end and rotated the pallet and the control froze and wouldnt respond to pressing any buttons. I powered it down and upon restarting the screen comes up white with random characters on the screen and doesnt repond to any buttons being pressed. I have tried turning off the main disconnect a few times and this didnt have any effect. This is the first time this machine has given any trouble. Any ideas?
