Like most others, I've been watching the explosion of Creality Cr-10's on the 3D printer scene. I would never recommend it as a first 'kit', if you want to know how a 3D printer actually works since you don't do anything except put 10 bolts in place and plug in a few wires. For a 3rd printer, with the learning curve under my belt, the machine looks pretty darn good but you're still dealing with the unscrupulous Chinese 'companies' situated on one floor of one building in a mega-city.
I joined the CR-10 FB group to see if it truly was as great as the YT videos say. Well, while there are a few having great luck, there's an ever-growing group of people trying to figure out why they can't print anything! There is so much bum dope being fed to those people that I just had to try to offer my suggestion on how to solve the problem. I prefaced the info with 'this works for me' and was quite rudely greeted by a returning remark from an 'expert' who said 'mind your own F*&^ing business" (expletive deleted). This wasn't the first time that I has such greetings. It's probably from frustration since none of these people have a clue as to how anything works. For we Folger Fanatics, we spent time on the reprap forum, Reddit, and everywhere else that we could fine meaningful information. These people didn't have to do any of that.
Also, I was VERY amazed to see the price for sub $400 kits now over $700 on Aliexpress. Banggood and Gearbest still are advertising units right at $400 but there are a lot of negatives being thrown around the FB site about their service and the quality of what you get AND DON'T GET. A lot of parts missing. Also, on Gearbest I noticed that they are referring to their offering as a 'kit' where you will learn the machine by putting it together. I wonder if they are actually shipping the pieces rather than an assembly. I can understand the $700 from a supply and demand standpoint plus the latest version has two Z motors and filament sensor.
I objected to the language thrown at me on the FB page and was told that I was 'off topic', so I said adios to them.
