I recently upgraded my plasma table software and found out it isn't compatible with my old software file formats, even though they are from the same company. I need a way to convert a .cn2 file (cnc-2) to ANYTHING else, hopefully .dxf but I can't find any software that can open a .cn2 file. Can anyone help? The software used to make it was ProMotion Nest, which is about 8 years old, and I still have that software but the version we have won't let us click on the export button. Hypertherm said they would have to build custom software.Thank you for any help.
