: Ensure A4988 or TMC2209 drivers are oriented correctly; reversing them will fry the board.
: Set the micro-stepping jumpers under the drivers before powering on.
: Most boards support mechanical switches (GND and S) or optical sensors (requires 5V).
: The TTL/PWM signal typically uses the "Laser" or "Spindle" port depending on your firmware configuration.

The primary documentation and manuals for the Makerbase MKS DLC v2.1 (and the 32-bit DLC32 variant) are hosted on the official Makerbase GitHub repository. This repository contains the hardware schematics, pinout diagrams, and firmware configuration files necessary for setup. Essential Manual & Data Links
Hardware Schematics: The MKS DLC V2.1 SCH provides the full circuit layout.
Pinout Diagram: For wiring limit switches, lasers, or motors, refer to the MKS DLC V2.1 PIN guide.
Wiring Manual: A comprehensive MKS DLC32 Wiring Manual covers power input, motor drive settings, and laser module connections.
Firmware Guide: For users of the 32-bit version, the DLC32 User Manual details firmware flashing via the MKS GitHub Firmware directory. Setup and Configuration Highlights
Power Requirements: 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).
Firmware Selection: The MKS DLC supports GRBL firmware, while the DLC32 version uses ESP32-based firmware. Both can be configured for either Laser or CNC mode.
PC Connectivity: The board uses the CH340 serial chip. Ensure the CH340 USB driver is installed on your PC before attempting to connect via USB.
For community support and troubleshooting, users often frequent the LightBurn Software Forum or the FluidNC Wiki.
