Laser Plotter Controller Board – Arduino, GRBL and EasyDriver

I have been working on a controller board for a laser plotter.
This board has headers for an Arduino UNO and two EasyDriver stepper motor drivers and integrates an LM317 laser diode driver.
It is designed to be used with GRBL, supporting 2 Axes, limit switches, laser ON/OFF, …

I attached some pictures of the board, as well as the Layout as .pdf and the KiCAD project folder as .zip
