!!top!! | Linuxcnc 2.10

LinuxCNC 2.10 (currently in development as the branch) represents the cutting-edge evolution of the open-source motion control software. While version 2.9 is the stable release, 2.10 is where new features and "risky" changes are implemented before they are finalized. LinuxCNC Forum Key Features and Updates

Not for Production: Do not use 2.10 for critical commercial work; unexpected "HAL parameters disappearing" can cause machine crashes. linuxcnc 2.10

With the release of LinuxCNC 2.10, that changes. This is not a minor point release. It is the most significant architectural and user-experience update since the project forked from its NIST origins. LinuxCNC 2

A major shift in the Hardware Abstraction Layer (HAL) moves pins to 64-bit architecture, allowing for higher precision in data handling between components. Trajectory Planner Overhaul: Use rtapi_* calls – same API, different backend

• Use rtapi_* calls – same API, different backend.
• No more #include <linux/module.h> directly – use rtapi_app.h.
• Build with halcompile (preferred) or the new kernel module build system.

Warning: Custom HAL files that relied on specific ordering of thread execution may need manual tweaks. If you have a complex setup (e.g., an automatic tool changer), test thoroughly before production.

• No lag on remote connections.
• Run your CNC headless (no monitor needed after setup).
• Control from a tablet/phone in the shop.
