Looking for some advise. I have setup about 600 LEDs 2812b running on a ESP8266. The first 382 are running off a continuous power line, 12 to 16 gauge wires coming from a 60a 5v power supply. I use a logic level shifter for the data to the first led. No problems up to this point. I will also add that I have 2 breaks in the LEDs at about 200 and 280 where I have only connected data line between the strips. Each break is about a 10’ gap. Power is added everty 6 feet or so.
The problem: I continue on to led 383 and they begin to flicker. At this point I have another 10’ break between 382 and 383. I have only connected a data line. The new strip starting at 383 is connected to the same power supply (5v 60a) but using a new run of wire. Trying to keep the load down under 20 amps per wire run. Voltage reads at about 4.8.
Should I be connecting the ground between 382 and 383? Could 382 be corrupt and sending a bad signal. Looking for ideas on how to solve the flickering.
