Went through more issues with printer than I can remember but one thing remains... level your bed, kids! Hate bed leveling with a passion so I ordered sensor, I hope it will spare me of bed leveling. The single most important thing about your print quality is goddamn bed leveling.
Tried to be smartass and bough uber-cheap Chinese clone parts and installed them on my printer. Massive plastic flow issues which disappeared when I returned original parts. Will buy another clone, absolute overkill tho. Mosquito hotend based direct drive extruder. The original part is way too much money, hope shelling 50 for clone means machining of metal is very good.
Thanks to this hobby I learned basics of:
chemistry (thermoplastic, silicon, metals)
carpentry (enclosure building)
3d design (to make and modify STL files)
microcontroller programming (Arduino)
electronics (PCB design, soldering, advanced multimeter skills)
painting
Yet to touch:
3d scanning
If you are lucky 200 dollars you spend on printer will go well and you won't have to fix or modify the machine. I bought used and abused so I have to tinker with it and there are so many aspects of CNC machine, in this case, plastic squeezing printer.
Why I bought a 3d printer? Well, it's new and fresh hobby while gaming became stale and commercialized to the point every normie does it. Sure, PC gaming was hip some 20-25 years ago when there was one PC owner per square kilometer in my country but right now it is worse than eating MacDonald's burgers or spending time betting on football.
Seeing how Chinese absolutely dominate atm and their strongest suite is manufacturing, also taking into account the agenda of the modern world elite where it is desirable to be stupid, uneducated and incompetent I find it an absolute necessity to learn a bit about what every Chinese preschooler already knows.
