I want to install the latest version of Grbl on my S3 controller. I downloaded the source from GitHub, modified the config.h file and compiled the hex with the Arduino compiler.
I used my USBTiny programmer to flash it to the controller and it appeared to load fine.
But when I connect with bCNC it doesn’t seem to be responding correctly. It makes the connection, but Grbl doesn’t appear to be responding.
I’ll be doing some more troubleshooting this evening but I was wondering if there was a list of any special S3 specific settings in config.h that I might have missed.
