Can flip bottom layers about the X axis.Converts Gerber format plot files into GCode files which will engrave isolation cuts around the PCB traces.It seems to work well for me - hopefully it will do so for you too. It is intended to be a one-stop-shop GCode generator and methodology which will produce consistent results when cutting circuit boards.
The GCode it produces, if run sequentially, should also provide a method for reliably producing nicely aligned, double sided isolation routed PCBs including the cutting of border outlines and the drilling of pad holes and vias. However, Line Grinder is intended to be a bit more than just the software. Line Grinder is a software package which can generate isolation routing GCode from the Gerber format plot files output by most PCB design programs.
You can download it at the bottom of this page. Since the software might well be useful to others, it has been released under the MIT license as free and open source. for better or worse I decided to write a package which would run natively on a Windows platform and which would provide the functionality I wanted in regards to PCB isolation routing GCode. The evidence suggests I am rather clueless about such things. Thinking back on it, the relative scarcity of Gerber To Isolation GCode software should have been a really big warning light telling me that this is a not an especially easy problem. An overview of the available options is available on the Gerber To GCode Isolation Routing Summary page. A search for Gerber to GCode isolation routing packages was performed and, indeed, some were found - however each had their drawbacks. This turned out to be quite a bit harder to do than I imagined it might be. The intention was always to eventually use the router to create PCBs for other projects, so the logical conclusion was that it might just as well to get it over with and figure out how to isolation mill PCB's now rather than later. Especially as, by the time proper circuit boards were required, the Wellity router was pretty much operational using perf-boarded circuits. Given my distaste for spending money, I was loathe to purchase commercial PCB design software and have circuit boards professionally made. The original project (the Wellity CNC Router) needed circuit boards - and some pretty big and odd shaped ones at that. None of the help files have yet been updated, that too will be done ASAP.Īs so often happens when working on a project, one day I found myself in the position of having to undertake an entirely new project just to keep the original project moving forward. The Gerber X2 spec is mostly supported but Aperture Macros are now supported as is circular interpolation. As of MaLineGrinder is back under active development and after a long hiatus has been upgraded to version 3.x.
