Is it a Mitsubishi or Fanuc control? If so do you know what system #?
For the communication, either Fanuc or Mitsubishi, if they have brought the communication out to a 25p D connector then it should Be standard RS232 and you can jumper the handshake out both ends 4-5 6-8-20.
I am not familier with the Mazak laser so this is general information. For e.g. the error 301 on recent Mazak/Mitsubishi is 'single block on' but I doubt if that is the case here.
