The laser rastering work might be relevant, that requires a constant photon density in much the same way as FDM requires a constant material density. The example on the Wiki (G-raster?) is really very clever. Much cleverer than it would have needed to be if inserted at a more sensible layer. > Similarly, ladder logic offers interesting possibilities for an extruder > "tool changer".

I keep trying to persuade Pete to make an SSR / thermocouple module. It's possible that one is on the way. It seems to me like a really useful 7i76 smart-serail plug-in board. -- atp If you can't fix it, you don't own it. http://www.ifixit.com/Manifesto ------------------------------------------------------------------------------ Master Visual Studio, SharePoint, SQL, ASP.NET, C# 2012, HTML5, CSS, MVC, Windows 8 Apps, JavaScript and much more.
