SURPRISE! 🔥 New Hidden Feature in Snapmaker U1 Firmware V1.4 (Not in Release Notes) #snapmaker #u1

I found something that wasn't listed in the official release notes for the Snapmaker U1 stock firmware V1.4 — a brand new UI control on the touchscreen! In this video, I start with a big 'SURPRISE' because honestly, I wasn't expecting this either. The new firmware now shows 'Top Cover Detected' on the screen, followed by an all-new interface that lets you control two fans independently — exhaust and recirculation. The best part? My DIY fan cable is fully supported. I tested both fans from 10% to 100% speed, and you can hear the noise difference clearly as they ramp up. Everything works flawlessly. If you've updated to V1.4, go check your touchscreen — this hidden gem is waiting for you. 🔧 DIY fan setup shown in this video 🎥 Real-time fan speed control from 10% → 100% 👂 Fan noise captured at every level Have you found any other hidden features in V1.4?
