bigtreetech / BIGTREETECH-Relay-V1.2

BIGTREETECH Relay V1.2 is an upgrade of the original (BIGTREETECH V1.0). After upgrading, a small MCU was added on the module to make the module more controllable and stable. Besides, we have also increased short circuit detection circuit. After connecting the 5V and GND on the motherboard to the module, if there is a 5V short circuit, the module will immediately power off to prevent damage on the motherboard and the risk of fire caused by short circuit.

I compiled marlin firmware on skr mini e3 v3 and the relay when i switch on the relay goes from on to off, then i have to press the reset button then it comes on and stays like that. Is it normal ?

ketterl commented 1 year ago

That is normal, some kind of security feature... There is a new firmware in one of the other issues that will change the behavior.
