Arduino mega 2650 chipset
It's a D6 MB with Marlin 1.1.9 firmware that I have been able to modify and understand.
It can connect directly to a computer via a USB cable and I have found that "pronterface" can directly connect to it and move the steppermotors.
My next step is to get mach 3 and fusion 360.
The railing system should be the easiest part but still needs to be made.
