Re: Dyna Myte 2400 and Mach3
I have no direct experience with the DM 2400, but the control is quite similar to the DM 3000H lathe that I have. That 25 pin connector that you're connecting to is most likely an RS-232 serial port for sending programs to the SKIP controller.
Sorry, you won't be able to just connect a PC with Mach3 and go like you're trying.

Re: Dyna Myte 2400 and Mach3
My DM2400 was retrofit (by the guy I bought it from) with a Centroid Acorn controller and a Gecko stepper driver. The Acorn talks to the PC via Ethernet. There's a 25 pin cable between the Acorn and the Gecko. Works very well. No issues.
