1. EMC Fest Cam

2. Intro

As they did last year, the EMC developers will meet at this year's [CNC Workshop], June 16-21, 2008 At Cardinal Engineering, Galesburg, Illinois, USA.

3. Planning to attend

Jeff Epler
Stephen Wille Padnos
John Kasunich
Chris Radek - arriving Saturday evening
Steve Stallings - arrive Sunday afternoon
Matt Shaver - arrive Sunday afternoon
Alex Joni - only online
Ray Henry
Jon Elson - arrive Monday afternoon?
Kenneth Lerman -

4. Planning to bring

Steve Stallings
- X1 minimill, stepper driven
Jon Elson
- 150 Lb servo-driven Minimill doing rigid tapping
- HP Laserjet 5M printer with ethernet interface (for use by all attendees)
- desktop servo demo/test board
- resolver to quadrature encoder converter with test stand
Chris Radek
- 5-axis mini mill
- mini lathe
Stephen Wille Padnos
- Test equipment (scopes and meters and stuff)
- Computers, but maybe not as many as last year
- Geckodrive G-Rex
- Some Mesa hardware
Ray Henry
- Eight Computers, a projector, and hub for EMC2 lab
- Sherline 4 axis mill and a bit of tooling for the lab.
- PLC and AC frequency drive for serial communication testing.
- CNC4PC MPG3 Pendant

5. Hope someone else brings

Some fat acme rod that fits in a collet on the Mazak
- I have some 1/2" Acme rod, what do you need it for? (Jon Elson)
Cheap DTI and accessories
- I have a couple DTIs, coax indicator, etc. If you want to do tests on the Mazak, I have a .0001" dial indicator and a .00005" Federal Maxxum (Jon Elson)
Some MODBUS devices, with documentation
Copies of ANSI, CENELEC, FM, IEC, ISO, OSHA, NFPA electrical and/or machine tool safety standards, European [Economic] Community Directives (EC or EEC), European Norms (EN), or any other standards, draft or published, of any age or origin relating to electrical controls and machine tools. The goal is to learn as much as possible about designing standards compliant machines and electrical controls. (Matt Shaver).
Equipment or instruments to measure RFI, or practical information on the subject of accurately AND inexpensively measuring RFI emissions (both conducted and radiated) from electronic equipment with the goal of detecting (and ultimately reducing) RFI generated by machine tool controls, including VFDs and axis motor drives (Matt Shaver).

6. Things we hope to discuss or work on

Chris Radek
- Joint constraints
- Concave cutter compensation
- Rigid tapping time-lag compensation
- Gear change G or M code/s
Ken Lerman
- GWiz -- G code wizard system
Stephen Wille Padnos
- Misc HAL improvements
  - Userspace "somewhat real-time" HAL threads
  - Better hardware checking (tell the Motenc driver that there is one board, and it will error if 0 or >1 boards are found)
  - Possible sim mode drivers
- Ways of doing machine configuration that are closer to commercial controls
  - Definable G-codes, as macros of some sort
  - Parameter access with EMC2 running
  - User interface configuration
  - Improvements to pyvcp and whatnot
- Small-system EMC2/HAL uses
  - Other architectures, like ARM, XScale, AVR32 ...
  - Realtime on standard kernels, like Posix.1b and/or the -rt patchset (should be good enough for servo systems or stepper systems with extra hardware)

Bugs to work on
- Threading bounces around with too coarse spindle position resolution
  - Making a component that deals with 1PPR spindles would also fix this I think

7. Workshops, Presentations, Classes

[Details]

8. IRC

IRC sessions for global participants:

where: #emc, #emc-devel at freenode
when: throughout fest (to add specific meeting times)

9. Mazak Motor Mount Project

Roland plans on running the Mazak to produce some motor mounts for a lathe retrofit. Details on this project can be found here. Project Page
