Hi, I'm new to CNC and I'm just studying the CNC software but I have a question, I make my models in AutoCAD (and keep the extension. DXF course) and then passed it to LazyCam, but I wonder if you could merge lines not to exceed the limit lines in the demo version of mach3, then ... these lines may merge or there is another method to display all lines in mach3 aside from buying a license? I would greatly appreciate your answers



Greetings! 

If the lines are collinear, then "merge" them in AutoCAD. That's your only option.
Note that a line in Mach3 is a move from one point to another. An AutoCAD polyline with 10 segments needs 11 lines of g-code.

Thank you, I'll try and then I'll tell you how I was, thanks
