I am trying to install the BL touch on my Alfawise U30 with V08 card. I unsoldered the capacitor and took the 5V from a stepdown connected to the power supply. The BL touch remains with a steady red light when it is on and off when it is down but does not move the servo and when I command it, it starts flashing quickly, what can I do?
I use a 3D touch, a clone
