Hi

A customer of mine has got a Hartford vmc 850 with a meldasmagic64 control the machine had a hard drive boot issue, I have now sorted out the hard disk, But, whilst the machine was down the parameters were lost from the NC card. I have managed to get the parameters and plc restored from a backup and got the machine back running again. Everything is now running fine except when a G03 or G04 is executed the axes don't move and the control just hangs up.

Anybody got any ideas?

Thanks Andrew
