A chronological log for Chuck Harrison, occasional off-site collaborator.

sync grbl to upstream..success.
replaced mechanical microswitches on X1-X2 axis with photointerrupters..success. Testing
contact Kavitha to coordinate torch table prep for Dec. 18 CEB build.
research CNC oxyfuel torch cutting [CNC_Torch_Table]
research onsite oxygen generation (PSA)
order some gas valves off eBay

got update from FEF regarding Dec 18 CEB build: no oxyfuel, using PP60 plasma on torch table, new tool chain with ImplicitCAD

start log.
ship Millermatic 200 welder (Seattle craigslist) by LTL truck to FEF. 400 lbs for $500; was that reasonable?
steppernug (open source stepper driver) schematic review with Darren
received photointerrupters for torch table testing
looking into "does not quite reach position" bug in my grbl branch

First contact with OSE Sept 2011 briefly on site. I was in the area visiting relatives David Ihnen and Margaret Havens.
