Hi,
I am new to this CNC field. I recently purchased a 3040T-DQ CNC (USB CNC ROUTER ENGRAVER ENGRAVING CUTTER 3 AXIS 3040T-DQ BALL SCREW USB PORT | eBay) machine with controller. (on the way). I am planning to use this tool for a different application hence I need to control it with my application which is being developed with MS C#. This unit has a USB port but I am not sure if it like FTDI RS232 USB to serial) interface or pure USB. I have never used pure USB but much familiar with USB to serial interfaces. Any one knows what is this interface ? ( I want to make use of this controller as it is and not want to replace the controller with any arduino shields).
Could some one shed some light about this ? Any help ? I mentioned about the arduino control since it uses simple USB to serial interface. In my real application, my C# will send the gCode to CNC controller when I have the connection. So trying to understand its interface/port info.
This unit says it supports only USBCNC. Not yet sure where to find the application.

Thanks for the help in advance.

Thanks,
P.

The USB on that CNC unit means that instead of a parallel port it uses the USB for controlling the steppers, it`s a USB to serial type control board, you can use arduino or raspberrypi on that machine for a simple G-code programs, but for the machine stability you might end up controlling it with an old PC and control it with MACH 3, I tried one before but with some heavier codes sometimes it freezes in the middle of the program and sometimes it just crashes on the material, for a simple outlining and profiling program yes it can work but on a 3D complex codes you will end up why it just hang up and stop working.
