+Here are some comments on a workflow to get a cutting file for the MicroProto mill. I am happy for this tool to be on essentially permanent loan to the space.
-added typed text
+The mill itself is a MicroProtoSystems DSLS3000. http://www.microproto.com/MMDSLS.htm
+It can accommodate pieces with X = 12", Y = 5.5", Z = 6" and they claim a "Position increment resolution" of 0.000125 in with a mechanical repeatability of 0.0005 in.
+The original documentation is in the green binder.
+I am not really up to speed with Fusion 360, and I am very rusty with the whole CAD/CAM process. But now the mill is running again I want to get back uup to speed with it. As Fusion 360 is what several people are working with I thought I'd try to figure out a workflow starting from there.
+Most of the problems I have had getting files ready for the mill usually seem to end up connected with some sort of scale issue. Fusion 360 does have an option to write a Mach3 cutting file. When I have tried this I get a file that has cut limits in Mach3 that are ridiculous (a 2" x 2" piece may show a cut boundary of 10,000"). Steve has figured out which lines in the G Code seem responsible for this, but I think hand-editing a G code file is a risky habit to get into. And there are lots of other ways to "get from here to there."
