OK this is weird, I uploaded the Langmuir Crossfire Generation 2 and Crossfire Pro plasma CNC break in program and when it opened up there was the Openbuilds control system as in the blackbox. What gives ?? Langmuir has its own software/control system for plasma CNC called fire control
You probably have Gcode files associated with CONTROL. Your choice, uninstall CONTROL, Fix the windows Associations, or dont double click the files, use the File Open menus in each application as relevant
If you have multiple machines running from one control machine, you may be able to cheat Windows and assign different extensions of g-code files (.nc, .gcode, .ngc, etc) to open in different controls, then save the right type depending on which machine you're going to run it on.
