Hi all,

I have a new (to me!) Hurco BMC30/M with Ultimax 3 controls. On boot up, initially I got the 'Security device missing or faulty' message but this goes away if I leave the machine on for a while then restart.

On restart, it gets stuck at the 'machine configuration' screen. PC seems to still be active as e-stop message still comes up if I press an e-stop. But the F8 (exit) button doesn't do anything.

I have also tried 'enter - 8 - enter' and 'enter - 999 - enter' but no reponse. On the board under the keypad there is a green LED that flashes when the keys are pressed, but it only flashes when pressing some keys (not the F8 key!)

I have re-seated all connectors within the keypad board and re-crimped the ribbon cable running from softkeys to control PCB. I have tested the mechanical function of the F8 key using a multimeter.

Where can I connect an external keyboard to try this? I couldn't see any obvious connector on the PC at rear of the machine.

Any help much appreciated!
