Knowing absolutely nothing, I first picked the Sovol SV06 because is was a strong recommendation from Reddit for the price I was willing to pay.....turns out its nothing more than a toy. In fact all these bed slingers are. All this modding and manual work is not something a normal person wants to do. It like we are still stuck in the 1970s computer kit building era and everyone in the community is in denial.
Out of pure desperation and considering my hard deadline of DEFCON, I bit the bullet and bought a used Bambu Labs X1c. This machine is in a class of its own for 3D printing newbies. I just load the filament, slice my model in their easy to use software and click print. That printer saved me big time. I consider it the absolute bare minimum for 3D Printing for people that dont really care about 3D Printing.
I hope that the X1c or something like it eventually reaches a price point where it is accessible to the mass market and becomes the bare minimum standard of quality and ease of use. Anything less will keep 3D printing as a niche hobby. Kinda like how we went through decades of really awful inkjet and laser printers to now get printers that are cheap, accessible to anybody by being plug and play and straightforward and fairly ok in reliability: basically an extremely mature market.
One more note about open source: There is no "open source" desktop laser/inkjet printer and people get on with their lives regardless. The 3D printing community embracing open source is an artifact of it still being stuck in the "computer kit building" era.
