For specific wiring needs, such as connecting a probe, you can find detailed pinout diagrams and community discussions on GitHub. A Z-probe, for example, can be connected using the A5 (signal) and Gnd pins.
The Ultimate Makerbase MKS DLC V2.1 Guide: Manuals, Pinouts, and Setup
What distinguishes the DLC v2.1 from a standard microcontroller is its integrated design. It consolidates power management, stepper motor headers, and specialized interfaces for lasers and spindles into a single, compact footprint. Its versatility is its greatest asset; with dedicated pins for TTL laser control and dual Y-axis outputs, it simplifies the complex wiring typically associated with gantry-style machines.

: Ensure A4988 or TMC2209 drivers are oriented correctly; reversing them will fry the board. It consolidates power management, stepper motor headers, and
After wiring and flashing your chosen firmware, you can connect to the board.
Since the MKS DLC v2.1 runs GRBL, it is compatible with a wide range of open-source software. Recommended Software The best free option for laser engraving.
Connects to a standard 3D printer-style power supply. Ensure polarity is correct (V+ and GND).
Connect the TTL/PWM pin to the Laser connector TTL pin.
