Software
LightBurn
USA based third party software that is much more user friendly. The "DSP license" edition is what you need to work with the Chinese RuiDa controls. It costs $120 for this edition. Free trials are available! The long-term plan is to have the software on a dedicated PC next to the machine.
You'll want to add the RuiDa device manually by IP address (after configuring to have your Ethernet card with a manual IP in the same subnet), and tell the software the correct working area of the machine, and that the origin is the top right.
RDWorks
NOTE: I do not recommend using the Chinese software!
The original Chinese software designed for their controls:
Download of Motion Control Software and V8 software-Ruida Technology (pick the RDWorksV8 category on the left)
