Not so long ago I bought my first 3D printer. It hasn’t shipped yet, but I’m gathering knowledge so hopefully I’ll be able to use it when it arrives.
One of the things I noticed while choosing the printer was that many specified “perfect first layer”. What’s so special about it? What should a beginner such as I know about it?
Prusa has a stellar knowledge base for their printers as well as general info that can be applied to most other printers. You’ll get some pla with the printer and I recommend loading the silver one to do the calibration with. You’re looking for enough squish, there’s a long lead in before the square for you to live adjust z, basically want a nice square that’s cohesive but not peeling up in the corners, too low can cause adhesion problems as well. There’s a good bunch of sample pictures on the prusa knowledge base.
Ellis’ Print Tuning Guide is another solid resource that’s applicable to most printers, not just vorons, the first layer squish is detailed and can help give you some more samples of what you’re looking for. Just make sure your sheet and nozzle are clean before you start, cold nozzle ooze can impact your z calibration.
