So I bought the Ender 3 S1 when it first came out. It has been great. I have spent the last two years printing with it all the time. It has been a ton of fun. I do regular maintenance on (tightening belts, swapping nozzles, cleaning and apply dry lube to the Z lead screws).
I set up a print the other evening. It started to level the bed and I went to sleep. When I came down in the morning, there was nothing on the print bed. I assumed that the filament had broken and the runout sensor had tripped. But that wasn't it. The UI screen was dark. I could see one of the print head fans spinning. I could hear the power supply fan spinning.
I figured maybe it just needed a reset. So i turned the printer off. Unplugged it for several seconds and plugged it back in and then turned it back on. Fans all spun up. But no movement and nothing on the UI.
Not sure what to do. Replacement main board is ~50. Replacement UI board is ~40. But a brand new S1 is only $179 at microcenter. Or a new, faster Ender 3 V3 SE is about the same price.
Does anyone have any troubleshooting tips for diagnosing the issue?
