First FYI, i am terminally novice at this and struggling to achieve this successful upgrade. I would be ever-so-grateful if someone could hold my hand and guide me to success with this.
That said, here's my details, and i'll give as much pertinent info that i know to give.
I have an Ender3 with a v4.2.2 board, and Marlin 2.0.6.
I installed a 3DTouch, and that's where i'm stuck.
The Firmware allows verification (successful testing) of the actual installed 3DTouch via the BLTouch menu options. Beyond this point, i don't know how to proceed. I cannot (via menu) make the print head move on any axis...not even a "try" sound from the motors.
