-Open driver for GCC Spirit LS
+Open drivers for GCC Spirit LS
 ===============================
 
+The driver for Fabmodules can be found here:
+https://github.com/jonnor/fabmodules
 
 Status
 --------
-Proof-of-concept in progress
+Can cut/engrave paths with correct proportions,
+including upload to printer.
+PPI, speed and power settings are respected.
+
+TODO (prioritized):
+
+- Fix laser being turned on before the first point (critical)
+- Fix output being flipped vertically (workaround: flip input image) 
+- Verify job offset being applied correctly
+- Fix/enable relative job origin
+- Fix hardcoded scaling factor with correct logic
+- Add more workflows in Fabmodules (especially from .svg)
+- Add automated tests: .svg/.path -> .gcc
+- Document usage/setup
+- Upstream the support to fabmodules project
+
+Later/maybe:
+
+- Implement native raster support
+- Integrate support in Lasersaur app
+

-* Modify driver according to spec
-* Test test test
+Dumped some output files from existing driver to figure out how pen intensity/speed/ppi was encoded.
+Using "FILE" as the port of the Windows printer, as found under Preferences on the printer setup,
+was a very easy way to do this.
+Turned out to be 4-character 0-padded ascii values, for each of the 16 pens.
 
-* Video of a first cutting job
-* Add end-to-end automated tests.
-Input=dxf file, output=.gcc.
-Initially Simple geometric shapes

-Later:

-* Test fabmodules with existing driver+printer.
-Not possible, requires Universal or Epilog access?
+Recorded a short video of current status.
