Thanks to everyone for all the great information.
The system has the RS485 with the drivers that we provided from AXYZ. That was what I was having issues with. I'm not familiar with the Toolpath software. The old machine we used to do the drawings in Vcarve and the CNC had Mach 3. From the little bit that I've learned so far, this Toolpath software takes the DFX file directly. I'm planning on still using Vcarve to make the G-code and just use the toolpath as I did in Mach 3. I have the manual, and I'll be going over it in the next few days.
