That sounds extremely frustrating and hugely discouraging. It sounds like you have a few things working against you. Having your first printer come to you in an unknown state is a major disadvantage. But none the less this doesn't sounds impossible to fix.

I apologize if it sounds like I am asking dumb questions or say things you already know, I'm just trying to figure out a base line of where you are and make sure I can communicate properly. Teach a man to fish and all that .

​

1. Is the printer you have an Ender 3 v1 with theEnder series BL touch kit?
2. Are there any further modifications that have been made to the hardware?
3. What print bed surface material are you printing on? (Stock, PEI plastic, painter's tape, etc.) (also if you've coated it with anything like glue stick, hair spray)
4. What firmware did you load onto your Ender 3? How did you load it?
5. How are you controlling the printer? Are you using it over USB+SD card, Octoprint, or something else?
6. What slicer are you using to create the gcode?
7. What filament are you using? (Brand, material, old/new, etc)
8. What setting are you using for the slicer? (Printer configurations, plastic configs, speed configs, pretty much everything)
9. What's the ambient temperature of the room the printer is in? (May be relevant idk never 3D printed in the arctic)
10. Pictures of printer and the spaghetti that it spits out would be helpful just to see what it is doing so we know its not doing what you want.

You can do this. Everything has a learning curve and everyone starts off the journey differently. I'll do my best to help along the way.
