Free, open-source, optimized for laser engraving.
(Max spindle speed / Laser Max Power): Typically set to 1000 for laser applications so that 1000 equals 100% PWM power. Available under the hardware folder of the GitHub repository
What you are building (Laser or CNC router)? What stepper drivers (e.g., A4988, DRV8825) you are using? Whether your machine uses leadscrews or belts ?
If using a 3-pin laser module, ensure the pin order on your laser cable matches the MKS board layout exactly, as wire colors can occasionally be flipped by manufacturers. Firmware Configuration (GRBL)
If you are running into specific technical issues with your setup, please share , which stepper drivers you are using , or any error codes showing in your software console so I can provide customized troubleshooting steps. Share public link
Ensure the baud rate in your software is strictly set to 115200 . GRBL v1.1 will not communicate at any other speed. Ensure no other printing or engraving software is open and locking the COM port. Issue 2: Stepper Motors Buzz or Vibrate Without Moving
