The new packages are now available in the package repositories. Because this version is incompatible with emc 2.2.8 in several minor ways, it will not automatically be installed as an upgrade. For more information and installation/upgrade instructions, please see http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl?UpdatingTo2.3
Ubuntu 6.06 "Dapper Drake" packages should follow within a few days.
CVS users can get this release by checking out the RELEASE_2_3_0 tag (or follow bugfixes on v2_3_branch). Source tarballs are available from the package repository: http://linuxcnc.org/hardy/dists/hardy/emc2.3/source
Many thanks to all the contributors who have been working over the course of many months to deliver the many improvements in this release.
Changes since the second beta release:
- hostmot2: allow stepgen maxaccel=0 for 'no acceleration limit'. This is a slightly experimental mode, and using acceleration headroom in the hal file is probably still the best way to get a hostmot2 stepper system running.
- hostmot2: make each stepgen only use 2 pins instead of 6
- axis: in a non-trivkins machine in joint mode, do not display the joints that are not used
- stepconf: enable image-to-gcode and python g-code generators
- fix problem with full circles with G64P-
- make the center of rotation assumed by G96 include the g5x and g92 offsets, if applicable
- fix several obscure crashes and memory leaks
- update Polish, Italian, and German translations
Other changes and new features since emc 2.2.8:
- install sample configurations to /usr/share/doc/emc2/examples/sample-configs

- AXIS: configurable preview of gcode for multiaxis/rotational machines
- AXIS: honor Block Delete in the preview
- added 'vismach' directory to sample configs, with max5 configuration
- vismach improvements: trianglar plate and triangle mesh primitives, and ability to view model from all angles
- vismach improvement: allow loading of stl models
- added interpolated position to software encoder counter - allows threading with low ppr spindle encoder
- HALUI: new relative position pins show position with active offsets
- new realtime component: gearchange. selects between two scale factors, two min and max speed limits, and optionally reverses direction of spindle
- new realtime component: invert - outputs the inverse of a float (1/x)
- pyvcp: add rectangular LED widgets
- pyvcp: timer widget for things like timing a program run
- vismach; new arc primitive
- new driver for OPTO22 PCI AC5 adapter card
- AXIS: display error messages on the main screen instead of a popup
- PID saturation detector output pins for fault/runaway protection
- halscope: add a menubar for load/save configurations, logging, help
- honor [TRAJ]'s ACCELERATION settings when jogging/homing

- tkemc: separate sliders for linear/angular joints
- allow FPR/G95 canned cycles
- AXIS: optional large DRO font
- AXIS: new Polish translation
- new distance-to-go and current-velocity HAL pins
- AXIS: the jog increment now does not wrap with repeated 'i' keypress; using 'i' and 'I' prevents disaster when you press one too many times.
- FPR/G95 now works with the spindle going either direction
- AXIS: right clicking in the gcode window lets you "run from here"
- several new tool change configuration options: TOOL_CHANGE_WITH_SPINDLE_ON, TOOL_CHANGE_QUILL_UP, TOOL_CHANGE_AT_G30
- allow UVW to be specified in the TOOL_CHANGE_POSITION
- improve motion synchronization at the beginning of a threading pass.
- AXIS: continue to show the line where the program was aborted, in order to make it easier to know where to restart.
- allow setting of spindle, coolant, tool, tool length to persist across mode switches, to allow the user to set up the machine properly for a program restart.
- AXIS: do not display initial rapid moves after a tool change or tool length offset change. These were not useful to see and made the preview and extents display less useful.
- disallow MDI commands and program execution on an unhomed machine by default. The old behavior is still available with an INI change.
- improve the "move on line N would exceed limits" messages by telling which limit would be exceeded
- G10 L1 commands to set tool offsets, radius, orientation
- AXIS: "touch off" can now also set offsets in the tool table
- converted many parameters to pins for added flexibility. this does not require any configuration changes because setp works on both.
- new motion.spindle-at-speed pin can be used to cause motion to wait for the spindle to reach a newly-programmed speed at the beginning of feed moves.
- new component "near" which tells whether two values are roughly equal as determined by configurable parameters
- make hal_float a double precision type
- "maximum velocity" that can be changed during a run. This will slow down rapids and cap feed rates (except spindle synchronized motion) for dry runs. Currently only AXIS and halui allow you to set it.
- the Mesa firmware images are now in their own deb package, since they are large and many users don't need them
- several fixes and updates to the STG1 and STG2 drivers, including encoder index support for STG2

- lathe diameter mode (select with G7; radius mode G8)
- AXIS: block delete and optional stop buttons/indicators on the toolbar
- AXIS: save block delete and optional stop settings across runs
- fix g41/g42 in lathe mode. previously, right/left were swapped.
- fix deviation from commanded velocity due to differences between requested and actual servo-thread period (SF#2478266)
- maintain G92 setting, if any, across gcode runs and EMC restarts
- AXIS: allow the filename ~/.axisrc to be overridden by inifile [DISPLAY]USER_COMMAND_FILE
- AXIS: per-axis DTG readout
- tweak firmware package building: not on sim, arch "all".
- rename sim's emc2-dev to emc2-sim-dev
- documentation improvements
- french translation improvements
- romanian translation improvements
- stepconf: fix limit signals
