Ensure Positive (+) and Negative (-) match the markings on the board. Reversing polarity will destroy the board. 2. Stepper Driver Installation

Outputs the main input voltage to power the laser module directly.

Solution: The stepper driver current limit (Vref) may be set too low, or the motor wiring phases are mismatched. Adjust the potentiometer on the stepper driver carefully using a ceramic screwdriver. https://github

Makerbase maintains all of its open-source hardware documentation, schematics, and firmware repositories on GitHub. Below are the direct links to the official resources you need to set up the MKS DLC V2.1:

: Ensure A4988 or TMC2209 drivers are oriented correctly; reversing them will fry the board.

(and the 32-bit DLC32 version) are primarily hosted on GitHub and specialist hardware sites. Official Manuals & Documentation MKS DLC v2.1 Hardware Resources : You can find the Hardware Pinout PDF Schematic Diagram directly on the Makerbase MKS-DLC GitHub repository MKS DLC32 v2.1 Manual : For the 32-bit version, a comprehensive Wiring Manual is available via Solo Motor Controllers User Guides If you share with third parties, their policies apply

If your laser engraver uses two motors for the Y-axis, use the secondary Y-driver slot to run them simultaneously. 4. Laser Module Wiring

Once connected via USB (usually at ), you may need to adjust these settings in the console: $100, $101, $102 : Steps per mm for X, Y, and Z. $32=1 : Enable Laser Mode (if using a laser).

| Issue | Symptoms | Possible Cause & Solution | | :--- | :--- | :--- | | | No COM port appears when connected via USB. | 1. Try a different USB cable. 2. Install the correct CP210x USB‑to‑UART drivers. 3. Reboot your computer. | | Stepper Motors Not Moving | No motion; sometimes a high‑pitched whine. | 1. Check wiring between the board and motors. 2. Verify microstep jumper settings are correct for your drivers. 3. Confirm your G‑code sender is communicating. | | Laser Not Firing / M4 Error | Laser doesn't turn on; software gives an M4 error. | 1. Ensure you are using the correct Laser firmware. 2. The M4 command (for laser mode) requires the proper firmware support; try using M3 if M4 fails. 3. Double‑check the TTL/PWM wiring.| | Inconsistent Axis Movement | One axis moves opposite to the commanded direction. | Reverse the axis direction by swapping the two coils of the stepper motor or by changing the $3 Grbl configuration parameter. | | Inaccurate Positioning / Steps | Carved/engraved dimensions do not match the design. | Re‑calculate and adjust your steps per millimeter ( $100 , $101 , $102 settings in Grbl). | | Endstops Not Triggering | Machine crashes into the frame during homing. | 1. Verify the endstop is connected to the correct X‑ , Y‑ , or Z‑ port. 2. Check your Grbl homing cycle configuration ( $22 , $5 , $13 , etc.). |

I can help troubleshoot, or provide the exact wiring diagram if you tell me which one!
