Hurco VMX50 Moves randomly in different axis during program

[Tarquinn500]

Hi

I am looking for some help. We can load the program into the machine and away it goes. But it does random things without throwing up an error. I could plunge 100 mm in Z, Re run the programme and it could drive 30 mm in Y. etc

Never in the same place. I have found that the cabinet door fans were not working and it was warm in the cabinet. Could this have anything to do with this error? or just be a coincidence?

i would be grateful for any help.

Processor board could be getting hot making it do strange things
