-==Gerber to DXF==
+==Gerber to DXF (New, even more complicated workflow)==
+Okay, but I have a Gerber file (that someone gave me, so, no, I can't re-export from Eagle/KiCAD) and your laser takes DXF and I can't find a free Gerber to DXF converter.  What do I do?
+Simple!  (Not really, but it seems to work)
+  - Open the GTP file in Gerbv
+  - Export as PNG, 1016 dpi (this is arbitrary and is a leftover from a previous attempted workflow)
+  - Load PNG into GIMP
+  - Set DPI in Image->Print Size.  Take note of dimensions in mm
+  - Colour->Invert
+  - Colour->Threshold (about 3/4)
+  - Select->By Colour, click black
+  - Select->Shrink Selection (5 seems to be good) ***
+  - New Layer, white background
+  - Fill (whole selection) with black
+  - delete original layer
+  - Export as PNG
+  - Load PNG into Inkscape
+  - Trace Bitmap
+  - delete bitmap
+  - Note dimensions in mm
+  - save as DXF
+  - Load into Smartcarve
+  - Set the dimensions
+***
+  - New possible process from here? (avoids having to "trace" again in inkscape)
+  - In The Gimp, choose Selection->To Path.
+  - Open the paths dock.  Right-click on the path and choose "export"
+  - Name the SVG file to export.
+==Gerber to DXF (This one failed with 45 degree rounded-end pads. gerbv totally screwed up the export)==
