2. Planning to attend

• Jeff Epler
• Stephen Wille Padnos
• John Kasunich
• Chris Radek
• Steve Stallings - arrive Tues or Wed
• Alex Joni - only online

3. Planning to bring

• SWP:
  • A few computers (at least one with CD recording capability)
  • Some test equipment
  • Webcam of sorts + network hub
• JMK
  • Computers
  • 16 port network switch
  • Networked laser printer (maybe)
  • Test equipment
  • Goodies to swap
• Chris:
  • Computer etc.
  • Paper tape reader/punch
  • Mini servo lathe, maybe mini mill
• Steve:
  • X1 microMill with parallel port stepper drive
  • will try to bring a working touch probe (not sure it will fit this small mill)
• Jeff:
  • computer
  • pluto-p board
  • avr usb hid board

4. Wish someone else would bring

• A laser printer or reasonably fast inkjet
• Machinable wax, spiral taps
• Maybe a mini mill set up for probing

5. Topics for discussion

• Better separation of joints and axes
  • How to deal with this in the config files
  • GUI issues
  • NML/communications changes

• Setup / configuration (again)
  • Unified setup for "EMC" (ini items) and HAL (.hal files)
  • PID Auto-tuner
  • More graphical HAL configurator

• User interface
  • Possible additions to pyVCP or other configurable UI
    • 3D preview pane
    • other things that would allow someone to make a fully functional EMC2 UI without compiling/writing code
  • Remote operation
    • See if we can avoid requiring files to be in identical filesystem locations on remote and local machines
  • HAL Utils
    • Halscope load and save configurations (menubar + "File"?)
    • Halscope save plot data, and offline(?) viewer mode

• Under the hood changes
  • Packaging of dev tools
  • SMP RT kernel option
  • Off-line updating / bulk updating

• HAL changes
  • Larger data types, such as doubles, 64-bit ints, structs
  • Figure out how to separate loading and instantiation of HAL components
  • enums for parameters (and maybe pins), with exportable names somewhere (so a UI can give a human-readable list of options)
  • Automatic thread function ordering. Requires function dependency knowledge.

• Probing improvements
  • What would it take to allow someone to digitize a complex shape without a lot of wasted motion?

• Source code (re)organization (or better documentation of source file locations)

• Motion Synced I/O - review and implement missing parts?

6. IRC

IRC sessions for global participants:

• where: #emc, #emc-devel, #emc-devel at freenode
