Hi guys I am new in cnc field but use 3d printer for many years I design my models with OpenScad For one of my models I need transparent parts so I decide to cut them from plastic panel using cnc router I bought a Sain Smart 3018 pro cnc router and assembled it My problem that I don;t find the right way to convert the stl file for the grbl code I download a pyhton script that convert the stl to ngc file but it does not run on the cnc router gcode app when i esit the ngc file i see a remark that this is gcode for linuxcnc so it is not work for grbl Can you guide me what is the best way to preform the stl to g code ? Regards ahead Doron
3D printers uses "slicers" to convert STL to GCODE Well, for CNCs you use a "CAM application" to convert files (DXF, STL, etc) to GCODE: docs:software:overview [OpenBuilds Documentation] 3D CAMs (to support STL) usually aren't free. Fusion 360 depending on licence can be free, but has a learning curve. Vectric is easiest: See Vectric Products - OpenBuilds Part Store
for flat parts Sketchup Make 2017 + the SketchUcam plugin is a very good, simple solution. https://www.youtube.com/playlist?list=PLm728rLHCWOw-vRvTJwS_5MmKG1fs4sZ0
Another option, Estlcam supports STL with no conversion, and has grbl post for cam or can run Arduino type machine directly. Cheers Gary
