Troubleshooting

Can't find "#define CPU_MAP_ESP32"?

Change #define CPU_MAP_ESP3 to #define CPU_MAP_MIDTBOT instead.

Won't connect when compiling (Windows)?

Change cable several times, checking Device Manager for changes. If still no response, install "CP210x USB to UART Bridge VCP Drivers" from ESP32.net

Missing library?

Double-check that the contents of the "Library" folder in the Grbl_ESP32.zip file pulled from github are copied to the libraries folder ...Documents/Arduino/libraries.

"Hard resetting via RTS pin"?

It's done.
