I have a SG90 servo which is not working at all, what I did:
-Installed the GRBL with the servo
-Used 2 arduino Uno's
-Using the CNC shield which I also used 2
-The micro tower SG90 servo (used 3)
-12V power supply
The stepper motors works fine.
I'm not sure if I should be on suicide watch or Arduino uno + CNC shield+servo homicide watch...
Any help would be great.
Wait what ?
I take it you are following something like a destructable ooops instructable ?
If so please supply a link as you have not provided either a sketch or a schematic both of which would be very useful about now.
