MACH3 G CODE EXAMPLES SOFTWAREAnd hopefully these will not be needed anyway.Ĭan anyone please suggest the minimum G-code commands that will allow me to use G-code from other people, and to also allow my software to export G-code that should be usable by others?Īlso, I am after some simple G-code examples for testing purposes, preferably with no arc or tool offsets or anything complex and not too large (say under 1000 lines?). A lot of my work will remain 2D routing, but it will be nice to add tapered pocket features and some variable height profiling etc all in the one job file.Ĭurrently I have implemented a couple of setup commands, then just G0 for 3D traverses and G1 for 3D cutting, but no arc commands or tool offset commands. Now my goal is to be able to run 3D G-code and cut more complex shapes and to reduce my time as it will be more automated, so I won't have to keep loading new layers etc to do an entire complex job. I also have a 2D to 2D morphing system for doing tapered shapes etc. Previously I have mainly worked in 2D or 2.5D using mainly flat cuts of 2D shapes and layers etc. Hi, I am writing some new software for my CNC router and am adding a G-code command interpreter. ![]()
