LinuxCNC 2.8.0 has been released.

The full changelog:

  • Finally merge “Joints Axes”. Joints and cartesian axes are no longer treated as the same thing, making control of robots and non-trivial kinematics significantly tidier.
  • Add a script to automatically update to the new INI file layout and new HAL pin names.
  • Multispindle: LinuxCNC now supports up to 9 spindles.
  • Tandem axes handled properly, including auto-squaring.
  • Reverse-Run: Negative adaptive-feed will now run the G-code path in reverse.
  • External Offsets, axes may now be moved from HAL as well as G-code.
  • increase max tools from 55 to 1000.

  • Many Trajector Planner improvements.

  • M98/M99 subprograms: - Support Fanuc-style subroutines
  • Add G74/G84 floating tap cycles
  • Enable remap of M62-M68
  • Implement G52 offsets

  • G33.1 Rigid Tapping speedup, with optional faster return move
