Purchasing a CNC for our Small Business - Help us make a decision

V1.3 Hit STOP in web interface, can't load a new file, I lose zero - #7 by Geige

This is discouraging to say the least and tbh, I have my machine and writing on setting it up (the pro version:BB), and im just like, “what have I done”. Where can I get shielded cables with the correct connectors to protect my wiring?
