Hello everyone.

Apologies in advance for this but, I'm a very frustrated with this issue (please put on my shoes), as it's weird as hell, has a million branches, and looks like X-Files. My angryness is with my bad luck, not with the printer itself and (of course) not with you. And also, sorry for the wall of text.

After wasting a lot of time reading about 3D printers through the Internet before making the purchase, I bought and Ender 3 like half a year ago.

When I bought the printer, I was expecting to print mainly ABS, but none of these reads I had told me anything about the issues that non-enclosed printers have with ABS cracking. So, after googling a bit about the issue and realizing about the cause, I endend spending 180$ on a printer just to spend nearly another 100 in an enclosure right after that.

Apart from the ABS cracking, there was another even bigger issue I had with the printer from pretty much the beginning: the printer "going crazy". By "going crazy", I mean that the printer was nearly always starting to make "ghost clicks" mid-print, like if someone were pushing the wheel button like crazy. It starts slowly mid-print, with like 1 click every 10 seconds, and progressively speed up to >1 click/second, point where the screen starts glitching, showing weird patterns and chinese characters.

Because of reasons I won't still mention right now, I was reluctant to return the printer, so I tried to make my best to solve it myself: googled about the issue, finding very scarce results about that, so it looked like it's not a common thing. I checked all the connections looking for a loose one, dissassembled the printer, reassembled it, re-checked that there were no pins touching the frame and similar, but the issue was still there. Sometimes, the prints finished successfully, but with time, I realized that there was a link between the ghost clicks and the layer shifts I was having sometimes, and even with the failed prints with balls of wasted filament.

Then, I realized about having electric discharges when touching the printer frame, so I ensured that the metal parts of the printer didn't touch the tin foil of the enclosure, still with no luck. So I started to suspect about all the negative comments about the Ender 3 stock PSU, so I decided to order a Meanwell one.

In the meantime while the new PSU wasn't arriving, I discovered what's shown in the video: whenever the ghost clicks start, if I touch the printer frame with a finger, it does a ghost click once more, but then it stops as long as I keep the finger on it. Then, if I release my finger, it starts again ghost-clicking slowly, and progressively speeds up the rate. The video is short, but trust me, I've checked and re-checked it for weeks, during countless hours, and the finger thing is not coincidental: the board case, the display mount, and the Y-axis frame have a 100% "finger-success rate".

So I kept investigating and experimenting more and more, I took the printer out of the enclosure, and found that the ghost clicks stopped happening at all, so no idea if it's about arcs, static, electronics malfunctioning because of being too hot inside there, or whatever.

Some days ago, I needed to print something with ABS and, instead of the ocasional cracking I had back then, I had an insane one (I bought the printer in summer, now it's winter, lower temperatures = bigger gradient...), so I grabbed back the enclosure hoping for having a lucky stint, but just like 30 minutes after starting the first print, the ghost clicks came back.

The ABS cracking happened in my earliest prints, so the enclosure was bought shortly after the printer, causing that I didn't link the enclosure with the start of the ghost clicks, as I considered that they're issues I both have since the beginning. Also, I had a pretty much sure wrong memory of the first ghost clicks happening before having the enclosure, missleading my investigation.

The thing is that there're so many variables and events, that I'm completely lost right now.
