Hi, Im running Mastercam 9.1 mill3 on my 1985 Mazak VQC 20/50b mill. [ M2 control] I am able to send programs from the PC to the mill with just a few edits to the program before sending. Mazak runs the part just fine. Problem comes after the program is sent, the PC locks [crashes] up and Mastercam must be closed and reopened before any other work can be done. Very annoying if you didnt hit save 1st.....

Can anyone give me some feed back on what settings or features in the program I should look at?

Thanks, Erik

W've been using a 3rd party software to send programs since Version 8. I like DNC SERVER... http://i-logic.com/dncserver.htm
It's a free trial so you've got nothing to lose.

Thanks, I will check into that software.
