Even though you mentioned that Datron hasn't been cooperative, it's still worth contacting their technical support team. Sometimes, persistence can pay off, and you might eventually connect with someone who can provide assistance. If Datron isn't providing the necessary information, you might need to resort to reverse engineering. This involves analyzing the communication protocols and data formats used by the Datron machine controller. It's a complex and time-consuming process, but it might be your only option.
Look into third-party software solutions that specialize in connecting various machines and controllers. While you mentioned that Cimco doesn't seem to support Datron, other software tools might be available that can act as intermediaries between the Datron controller and your existing systems.
