Sunlu S4 Filadryer - Causes LED lights to flicker/flash

Cbass37 · February 26

I was able to get a Sunlu Filadryer S4 from their Kickstarter, and I love the ability to use 4 different spools at a time. The only issue I have is that the 120v LED bulbs and LED "shop lights" I have in my room start to flicker, and very noticeably. I have an Oscilloscope that I connected to my outlets and there is a noticeable fluctuation in the voltage rising and dropping 2-3V ONLY when this filament dryer is on. I have tried unplugging everything connected to this circuit and the oscilloscope still shows the fluctuations in the power. I am simply wondering if there is a cheap fix to this, be it a power conditioner, a back up power bank for it, or if I will need to run an extension cord across my hallway to have steady lighting.

Things normally plugged into this circuit is a MSI laptop (210 watt Power supply), Creality K1 3D printer, and an assortment of soldering irons, suckers, hot air guns. 2 of the LED "shop lights" and 5 of the LED 120v bulbs 2 of which are in the existing ceiling light fixture.. The circuit is a 20 amp breaker and is only ran to the one room.

If need be I can record the signal on my computer and upload it if that would help, hoping there is a simple solution.
