@dc42 Thank you very much for your help!

@dc42 If I send M672 S75 for example it blinks 4 times, when I reboot it blinks once. If I send M672 R it blinks 5 times, when I reboot it blinks once

@Phaedrux Yes sir it does.

@OwenD It's version 3. Which pin is the input (programming) pin?

@Phaedrux Thank you very much. I'll either figure it out or throw it in the trash. LOL

@dc42 It's a version 3, It's been powered up at least 30 times, I been messing with it for 2 weeks. Whats the command to put it into test mode, maybe it just mixed up! LOL

I'm using SKR V1.3 board with Marlin, it doesn't matter whether I hook the smart effector to zmin pin or the servo pin the lite blinks one time on power up, according to the docs it's in test mode. Any help would be appreciated.
