I am new to DIY CNC and I am using Chilipeppr with a UNO. I can get everything to work up to the point of hooking up my stepper controllers to UNO. How do I know which pins on the UNO to use for the step and direction wires for each axis? Seems like I missed something really simple. Must be getting old.
Thanks for the help.
it depends on which software on an Uno that you use.
if you are using GRBL then this page should be of help: https://github.com/gnea/grbl/wiki/Connecting-Grbl
Thank you very much. That is the information I needed.
