Hello and thank you for your work on GRBL_ESP32.
For a future CNC project in GRBL_ESP32 and external drivers TB6600 I was thinking of making a board with 5 axes (XYYZA) with 2 Y motor and driver for squarring my grantry. Do you think that to start I can start on the design of this board and add a 5th axis? Is there enough free pin on the ESP? I saw in the documentation of the ESP that some pins are not recommended ... Thank you.
PS: Sorry for my bad english. I'm french...
