I have a CNC router table that came into my local makerspace. The board looks like it has some standard parts, but also has some parts I don't recognize. At the heart of it is an Arduino Uno. I would like to get the code from the UNO, as a back up. I will have to do testing on this board, but I don't want to overwrite something I don't have a back up of.
is there a way to get the firmware off of the arduino, without having the ino files that generated it?
(This is a standard function on many other platforms such as PIC, I just don't know how to do it in Arudino. I am assuming the functionality also exists.)
