I'm new on here and come baring an issue. I've made an XY plotter for my first project, almost done - ish.
I'm using two old printers same motors etc, I've wired them both up, the exact same way. Testing them with one arduino board, they both work fine, but from my other board nothing. (both 328 boards)
I need 2 boards for the different paths the X and Y axis' will be taking. I've selected the correct options from both Tools > Board and > Serial port.
The board loads, TX and RX do their usual flashes, then nothing....
