I’ve been using the following instructable: http://www.instructables.com/id/Probing-and-Milling-a-PCB-using-an-Arduino-Based-C/?ALLSTEPS
It’s fairly straight forward; however, the Arduino shield they are using has dedicated Auto-Leveling pins. Any ideas on how to set this up for an X-Carve using gShield?
On the PCB Milling Project, John mentions this is plugged directly into the Arduino, but if it isn’t on particular pin(s) of the Arduino how does it let Chilipeppr know this signal is being received?
Also, do we need to upgrade the software of the gShield for auto-leveling to be allowed (do we just upgrade it according to the instructable)? Any help in this area would be appreciated.
