But you might have confused things by trying to run two CNC control programs at once. Do you have a dual-boot system, or are you using 2 different computers with this? Deciding which OS and control system you want to use will make troubleshooting easier. Did you get this used, from a dealer, or directly from Sherline? Did you get a setup file with it, was it preconfigured, or are you trying to configure it from scratch?
