    In the Grbl-L (grbl lathe version, there is also a Grbl-L-Mega version), an input pin is used to measure the spindle speed of the lathe. The same pin is used for G33 spindle synchronization threading.
  • I've been retrofitting an old benchtop CNC lathe to run GRBL and cut threads! Let me know what you think.

    The interface between the Teensy and Arduino is actually fairly simple. GRBL already has a built in spindle speed output using the Arduino PWM. The Teensy just reads the analog voltage from the spindle speed pin on the Arduino to set the speed. Similarly the output from the Teensy (the synchronization pulse) is just a digital pulse that gets picked up on the GRBL 'Probe' pin. Full details on the GRBL threading implementation are here. The spindle rpm should be reasonable stable under load since the Teensy is running a PID controller using the input from the encoder to keep the speed stable. This means that it can correct the rotational speed ~20 times per rotation.
