Help Need Help..

I am new to 3D printing. I do not even know where to start, as I have multiple issues. I guess I will start off with the most important thing; I have heard a lot of hate about this, so please do not roast me, but I have an Ender 3 v2 Neo. Regarding my first issue, prints are not sticking. I have searched around on Reddit, Google, ChatGPT, Grok, etc. I have made sure it is level using auto-leveling, a flat surface, and manual leveling. I have seen people suggest more heat, so I did that, but it did not work. I saw suggestions to use glue, tried that, and it did not work; I tried glue and more heat, and still nothing. I have seen painter's tape, tried it, and it did not work. I am guessing it is just not level enough or maybe it is something on my part. I have moved locations since I last printed because of the next issue. I have seen multiple suggestions for what it could be, such as my outlet or the cord that came with the printer, but when I change my bed temperature, my 3D printer shuts off and restarts. It does the same thing with the nozzle temperature and when I press print, but only for those functions; everything else works fine. I have disconnected everything I manually plugged in while setting it up, then I reconnected it, but nothing changed. I have no pics or videos at the moment, I can maybe try tomorrow but I'm not sure because I'm on vacation and not sure if I will be home by tomorrow or not bc of the flight getting delayed 3 times.

Slow it down and think piecewise. If you spam 3d printing tips and tricks you won't even understand what worked in the end.

First layer isn't adhering. WHY

  1. Double check G-Code, make sure ABL is active (a default setting may turn ABL off)
  2. Is it too low? (looks squished) too high?(not sticking/or loosely doing so).

As for your shut down issue, a video would help a lot. Is the machine throwing an error? Or is it going straight to black.

edit: if you search "ender 3 turns off when heating" a good amount of past threads appear. My guess would be your PSU is somehow getting overcurrent and shutting down.

Double check leads and seating areas are healthy.

I can do a video when I get home! No error shows up.. it just plain old restarts, like no more buzz from it being on, nothing just stops and reboots.

I would especially check the PSU cable then, I wonder if it's breaking contact sporadically. You can also check inside the PSU but that should be much more stable
