GRBL 1.1H has a dynamic PWM option that allows you to have a very nice greyscale and do photoengraving. Some older boards like CNC Woodpecker only support GRBL0.9 version and it works fine if you only do CNC milling. You may upload that firmware on different boards and run them. Most machines are fully compatible with it. By replacing the board you may upload or reupload any firmware you want. That means that you have to have a Benbox firmware. That means that your Acan or LaserAxe machine will only work with its own firmware.įor example, Endurance MakeBlock XY 2.0 plotter also works with Benbox only. That code can be universal like most machines have like Ortur, SainSmart and others but it could be very specific like LaserAxe or ACAN. That code depends on what circuit do you have, what motors do you operate, what is the wiring circuit for the laser. How to change firmware on your Eleksmaker Mana (a universal laser engraver) board into GRBL ( LaserGRBL compatible) and back to Benboxįirmware is a special code that is being recorded on your board (usually Arduino or Arduino compatible) to make your machine work.
