Just got back to Mach2/3 after three years and tried LazyCam. Having EXACTLY the same problem, and getting the same message however simple a DXF is imported. Something is fundamentally wrong here. If it will help, I have full DevcStudio installed for any debugging I can help with, and would REALLY like to het this working for a simple 2D milling job
Is there a test .dxf that can be downloaded to eliminate that issue?
