| 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.). | makerbase mks dlc v21 manual link

Instead of making you search through forums, here is the primary source for the official documentation:
If your CNC machine uses two motors to move the Y-axis gantry, insert a driver into the 'A' slot and use the onboard jumpers to configure it as a clone of the Y-axis. 3. Laser and Spindle Control
