I have a EleksMaker® ManaSE 2 controller board on a home built laser engraver.
The board has a Arduino nano and has been programmed with GRBL 1.1f
The board has only drivers for the motors and a laser module connection.
It is working fine, but I wanted to add a couple of extra controls for pause and resume, but the board doesn't have any connections for those.
It also doesn't have and limit switch connections which would be useful if they were there.
Can I add my own to the Arduino nano pins directly?
