EMC 2.2 has been released, and I'm the release manager. Hopefully my
learning curve doesn't cause too many bumps. Read the full
announcement, or below the fold for a summary of changes.
Changes in EMC 2.2.0
- G41.1, G42.1, G43.1 to take tool parameters from gcode instead of tool table
- split libposemath and libemcini from libnml
- new inifile item: [HAL]SHUTDOWN, a .hal file run at a clean shutdown of emc
- new component: tristate_float
- new components: clarke2 clark3 clarkeinv
- scara robot sample configuration with visualization
- opengl machine visualization for several "robots"
- M66 - digital input control (wait & read external HAL inputs)
- hal-8255 driver for a PCI multiple-8255 card
- tapered in/out on multipass threading canned cycle
- debug and print output from the interpreter
- named parameters in the interpreter
- sample configuration for a puma robot
- reduce quantization of the encoder module's velocity output
- MDI history manipulation and save in AXIS
- number of samples in halscope can be specified at runtime
- add 'source' command to halcmd
- add tcl interface to halcmd commands (tcl/hal.so)
- add "-U" (force unload) to halrun script
- image-to-gcode: roughing passes
- rs274.author: automatic arc recognition (used by image-to-gcode)
- Filters can now show progress bars in the AXIS window as they run
- U,V,W linear axes with fully coordinated motion
- probing in A,B,C,U,V,W axes is now allowed
- AXIS: touch-off in any coordinate system
- AXIS: allow starting an editor on the loaded gcode or tool table from the File menu
- AXIS: A much better Velocity display
- AXIS: Preferences set on the View menu are saved for the next EMC run
- Feed Per Revolution and Constant Surface Speed for lathes
- Index-only homing for configurations where homing on a switch is inconvenient
- G28/G30 now move only the specified axes to the home/reference point
- Improved error messages for incorrect arcs
- All combinations of inch/metric machines running inch/metric programs work correctly when using the tool table. The tool table is always in machine units.
- Now any combination of XYZABCUVW axes can be defined, and trying to move an undefined axis causes a proper error message
- Tool change position can have an ABC component. Previously rotary axes always moved to 0 for a tool change.
- Analog jogging in halui (for joysticks etc.)
- Fix several-second unresponsiveness when switching between two guis (even if one of them was halui)
- AXIS: Show machine limits with red dashed lines
- Pluto step/direction driver
- Halscope display now shows the trace name and parameters for each trace
- Halscope "AC coupling" of signals
- for SMP configurations, run EMC's realtime parts on the highest numbered CPU, since this can be isolated from the rest of linux using isolcpus=
- fixed a bug that caused helixes with a small circular component to have too low a feed rate
