![]() ![]() The Script can be modified to work with most machines. Freecad is so amazing we can do amazing things like Create a new freecad document, import a DXF file making sure your Scale factor is set to 25.4 for inch users then run a script to generate g code from the imported dxf. ![]() Freecad is for 3D modeling and is geared towards creating tool paths from 3D models and not simple 2D stuff. Freecad really is not suited for working with DXF and 2D tool paths generally. After doing a bunch of holes using my CadCam software I thought it would be nice to be able to import a DXF file with just the holes, run a script and generate the GCode for using my machines helical milling capabilities. I have a variable program I leave in my machine just for helical boring making life easier for quick tasks. ![]() ![]() This creates a lot of code and just is not cool. My Post for my CadCam software does not do helical boring but drops down the zdepth cuts the circular path then drops down again and cuts the circular path. The Cincinnati Acramatic A2100 Cnc mill I use has a helical can cycle like most CNC controllers do. NOTE: This is for DXF files with HOLES / Circles Only not meant to deal with other features like lines slim down your DXF to just holes Step3 Run the HelicalDxfToGcode macro and it will create the GCode This Script takes all the holes imported from a DXF and generates GCode for helical milling cycles.I created this for doing counter bores mostly. ![]()
