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.
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.
