Can someone help me with an issue I am having with adding LEDs to my Ender 3 V2 printer?
The LEDs worked fine when I tested them on a breadboard with my bench power supply but after wiring them into the printer they turn off after about 40 seconds then on again 5 seconds later. Off, on, off, on all the time.
I attached a picture of my notes. I am far from knowledgeable about electronics.
The LEDs are all rated at 3.1-3.2v and 20-30ma and they are all ran in series. Using a toggle switch on the positive wire (rated 220V 6A). After the switch, I placed a 10ohm resistor (1/4W). Power comes from the printers Mean Well 350 - 24V the printer runs off of one of the 24V outputs terminals and I put my LED wires on the other terminal that was free on the PSU.
Things I have noticed so far:
The voltage before the resistor is a steady 24.17 V (never changes) voltage after the resistor is 21.2 when I turn the led switch on, then over the next 40 seconds, it climbs to 21.38 before the lights turn off. At which point the V goes up to the 24.1V and then back down to 21.2 when the LEDs turn back on a moment later.
The printer seems to be unaffected by all this and the PSU seems to always supply the 41.2V and the green light on the PSU is always lit.
Any help with this would be greatly appreciated as I have limited electrical knowledge.
