2-pin ports separate the constant 12V power from the TTL/PWM control signal.
Supports both 2-pin/3-pin 12V/5V lasers with TTL. Annoy Tools CNC Board Wiring Diagram (PDF Guide)
Ensure the PWM/TTL wire is connected to the signal pin, and $\$32=1$ is set in GRBL. annoy tools cnc board manual pdf
Wire one end of your Z-probe tool to the Probe signal pin, and attach the grounding clip to your CNC router bit. 4. Software Setup and Configuration
Wood and metal chips can short out an exposed control board. Use an enclosure or regular compressed air to keep the PCB clean. 2-pin ports separate the constant 12V power from
If you'd like to get your machine running perfectly, let me know: The of your board (e.g., 3018-PRO, GRBL 1.1) If you are using a spindle or a laser The specific software you plan to use (Candle, UGS, etc.)
Use a program like Candle or UGS (Universal G-code Sender). Wire one end of your Z-probe tool to
Use the TTL/PWM pin for modulation (power control) and the 12V/GND pins for power. 3. Limit Switches (Endstops)
Candle (GRBL Control): The most popular choice for beginners. It allows you to visualize the G-code and jog the machine manually.
