Hi,
I have the dual switching hotend running on a skr 1.4 board with marlin firmware, but I don't know how to connect the relay for the servo or how to switch off the relay in Marlin after the servo movement.
I hope somebody can help me, since there are no instructions in the manual.
The question is the signal for the servo and signal for the relay the same signal pin? Do I use the same 5 volt and ground or different ones for servo and relay? A diagram would be helpful.
Hi Noel,
You can find the instructions for Marling here:
Note, you do not need the relay for Marlin, it is only needed for klipper.
