LED Strip Stays On After SLB Shutdown – Need Help Troubleshooting

I connected the LED lights following the instructions provided in the Technical Manual under the LED Strip section. However, after installation, I noticed the lights remain on even when the SLB is turned off.

I’m using a 5V power supply to power the rail lights, and I’ve used the recommended LED strips. I also updated the firmware according to the number of LEDs I’m using.

Can someone please help me understand what I might be doing wrong?

I’ve tried some of the code, but nothing seems to work!

Rail Ring
Auto M356 P0 Q0 M356 P1 Q0
White M356 P0 Q1 M356 P1 Q1
Off M356 P0 Q2 M356 P1 Q2

Any help would be greatly appreciated.

Welcome to the group, lots of good folks and resources here. I have the same set up on my system with the same issue. I put the commands you reference in as macros to turn them off. I often forget to run the macro before I quit g-sender in which case I unplug the power 5v power supply briefly which will turn them off until the next time you fire up the SLB.

@eortiz1 So, you have set M356 P0 Q0 and they stay on all the time?

Yes ,that is correct.

I left everything unplugged last night. I’ll try powering everything back up in a few hours after work and see what happens. I’ll keep you posted.

@gwilki They lights are staying on. After SLB is turned off.

@eortiz1 The only thing that comes to mind is the the + lead and the “signal” lead are reversed so that you are feeding the 5v directly from the power source to the leds.
I’m sure that Sienci tech support will get you fixed up.

I checked the wiring, and everything looks good. I’m wondering if the issue might be related to the firmware. I checked the voltage, and it’s reaching the lights, but they’re still not turning on. I also tested with the spare LEDs I have on hand, and nothing is happening.

At least you went from staying on even with slb off, to not going on, so something changed and that may supply a handle to grab onto.

What happened to have this digital 180 flip?

@eortiz1 I’m confused. Your title and first post say that the lights stay on even with the SLB powered off. Now, you saying that they never turn on. What changed?
@Spamming_Eddie Agreed.
