Upgrade your CNC router with automatic tool changing — no pneumatics, no expensive spindle upgrades. This self-build file pack includes all 3D printable parts to build your own spindle-torque ATC, compatible with ER20 collet spindles. Print, assemble, and run multi-tool jobs unattended.
⚠️ Compatibility Required: This ATC requires a CNC controller and firmware capable of macro execution and tool-change commands (M6, M66). The included macros are written for GRBL/grblHAL-based machines and have been tested on grblHAL specifically. They have not been tested on LinuxCNC, Mach3/4, or other controllers, and are not guaranteed to work without modification on those platforms. Please confirm your machine can run automated tool changes before purchasing.
No refunds on digital products. Watch the assembly video here https://youtu.be/lOLs0KqrZkg?si=hwRbxnW07gJf4_Ng
