What is the difference between an M39 and an M400?
The M39 uses a conventional PC keyboard and monitor, which you supply, and a handheld pendant for the jog panel. The M39 includes a support arm and tray. You can use whatever keyboard and monitor you like, from a surplus CRT to a modern LCD. The M39 computer is in the upper part of the electrical cabinet, usually on the side or back of the machine. The M39 is somewhat less expensive, and so appeals to the home market. Also, with its walkaround pendant, it is a good choice for large-format router tables. The M400 includes an industrial console, with the LCD display, keyboard, and jog panel built in. The M400 computer is inside the console, making access to the USB ports somewhat more convenient. Aside from the console/computer arrangement, there is no difference between an M39 and an M400. They run the same software, and have all the same software and hardware options available.
