We use Job Pack as our DNC software and found that our Mazak’s with the Matrix controls will not convert a program back into Mazatrol when loaded back into the machine. When you send it to the computer it converts it into the 3 digit G-code format correctly but when you send it back to the control it will not convert it back. This control has USB only so we had to get a USB to RS232 converter to communicate with Job Pack. I called Mazak about it and they said it can’t be done on the Matrix control but our Nexus controls have no problem sending or receiving. We have thousands of T-Plus and M-Plus programs on our server that the Nexus controls have no problems loading. Has anyone come up with a viable solution to this?
