Mazatrol 640T Nexus - How do we program M codes in conversationsal

mneuro · Oct 24, 2019

We just bought a used Mazak 250MSY lathe running the mazatrol 640T nexus controller. We have never done any Mazak conversational programming and we are struggling with it.

How do we program in an M code. Right now we are trying to turn on the coolant for a boring cycle, and put in an optional stop. Any help is greatly appreciated.

Go into program edit mode. Move your cursor to where you want to insert an M code. Insert a line. Choose M code and then enter the M code command desired. M8 is often the first line after the header.

Optional stops with Mazatrol are best handled with a manual process and not using the M-code process. If you put in an optional stop using the M-code process, the machine will stop with the cutter sitting in front of the workpiece and you will not be able to measure the part.

Use the manual process to move the tool to an X and Z position away from the workpiece, then on the second manual process line put in an M01.
