What is a .M3P file?
An .M3P file is a special kind of computer file that works with a program called Mach3, which is used on Windows computers. Mach3 is a special program that helps control machines that cut, print, or drill materials like wood or metal, following designs you make on a computer. These machines can be things like mills, which shape metal or wood, lasers that cut materials, routers that hollow out areas, and engravers that carve designs.
The .M3P file is like a helper for the Mach3 program. It's not a design file itself, but it's more like a tool that adds new abilities to the Mach3 program. For example, with the right .M3P file, you could use your Android phone to control the machines, or even use an Xbox 360 controller to move the machine parts around. This is possible because the .M3P file adds a .DLL file to the Mach3 program. The .DLL file is where the new abilities come from, but Mach3 sees the .M3P file as the source of these new tools.
To use an .M3P file, you usually find it inside a .ZIP file, which is like a folder that holds files together so they take up less space. Inside this .ZIP file, there will be a .DLL file that has the same name as the .M3P file. This .DLL file is the real source of the new abilities for Mach3, but you need the .M3P file to tell Mach3 to use it.
If you want to use an .M3P file, you need to have the Mach3 program installed on your Windows computer. This program, made by a company called Newfangled Solutions, is the only program that can open and use .M3P files. Once you have Mach3, you can add the .M3P file to it, and start using the new abilities it provides with your machines.
