Hi everyone, I'm new to arduino and would like to understand if a CNC shield can be mounted on the Arduino Mega 2560 board. I mean, does it fit directly or need any trick to be adapted? Thank you. ---

There are a couple of CNC shields that fit a Mega that I know of. The 4 driver GRBL compatable shield that fits an Uno or Mega and The 5 driver model that is for 3D printers that fit a Mega only (pictured). Both just plug onto the Arduino board. Careful alignment of the pins is necessary but no "tricks". What are you building? ![shield.jpg](https://europe1.discourse-cdn.com/arduino/original/4X/5/9/a/59a61805195e36fa30ee76678cb6e4b464de85f9.jpeg) ---
