Connect a 12V or 24V power supply. Ensure the polarity is correct (Positive to VIN, Negative to GND). 2. Stepper Driver Slots Excellent options if you are configuring the board
If you need the that originally came with the board, it is not available for separate purchase from Makerbase, but the PDF above matches that manual exactly. You can print it for a physical reference. Calibrate these values so a commanded 100mm move
Calibrate these values so a commanded 100mm move results in exactly 100mm of physical travel. Troubleshooting Common Issues
The is a high-performance control board designed for desktop CNC machines and laser engravers. It is widely recognized as a major upgrade over traditional 8-bit Arduino-based controllers due to its use of the ESP32 32-bit microcontroller , which provides integrated Wi-Fi, Bluetooth, and significantly faster processing speeds. Official Manual and Resource Links
The board supports 12-24V DC input. For high-power laser modules and multiple stepper motors, a 10A power supply is recommended. Laser Connection: S: TTL/PWM signal for laser control. G: Ground connection. V: 12-24V Power output (matches input voltage).
