Once you have ConnectCNC and your CNC machines communicating, we strongly suggest you take the following precautions: - Download some programs, the longer the better, from your CNC to the pc. Save them under a temporary filename so you don't overwrite the original files. Examine themfor errors such as dropped or changed text. Do this for the first few programs that you use.
These settings have been collected from users of our software and machine tool distributers. We have listed them to help users of ConnectCNC to communicate between their computers and CNC controls. Since we have no control over the many variables involved, including such things as cable conditions, modifications to machines, condition of computer hardware, etc., we take no responsibility for any damage caused to programs or machines through the use of this software.
