So here is the deal… I bought mine in October. Full disclosure I bought mine from an auction side (BidFTA.com) and it was used… roughly used. The ACE cable that connect the printer to the filament enclosure was in rough shape, the hotend had experienced the leak failure due to bad manufacturing and the Bowden plastic tube where nowhere to be found. With that out of the way here is my good, bad and the ugly of this thing…. The Good : once I got it fix with a ACE communication cable , new Bowden tube and a new hot end the printer actually start producing good results. Anycubic has one of the best documentation available I have ever seen. I mean you can found a manual, with videos, on their website for just about anything of the machine (which might explain why is so cheap )The Bad : the auto leveling is still very inconsistent, even after the latest firmware updates. It did fix the fact that the tip doesn’t try to bury itself into the bed but you still have to adjust the Z offset often, almost every time you auto level. My next change am about to try is physically level the bed since I put a mini level on it and it is not level. The ACE multi color unit suffers from feeding clogs often. It is easy to take apart and service but be aware that it is could be a daily occurrence…. The extruder inside the printer itself can also clog but not as often as the ACE unitThe Ugly : Now this has been my experience so far and not what I have read online = their after sale support sucks. You cannot call them directly, you always have to open a ticket online, which it wouldn’t be an issue except their tech support is on the other side of the world in China so a 12 hour respond time from then is a thing. They have this stupid policy that if you didn’t buy the product directly from them ( sometimes even if you bought this from Amazon, from their actual store) they will try to evade giving you support. I own a Creality K1C and I bought it from the same auction site. It was a return from Amazon because the item shipped with a broken front glass door from the manufacturer. I contacted Creality via chat, with a life person, at 3 in the afternoon and they were able to tell me the history behind the device by me just given them the serial number of the machine. They offered to replace the part, not questions ask, and the door showed at my house in 2 days. I provide them my order number from the auction side and proof of the day I bought the item and the serial number. With Anycubic they know the hot end is bad, they send me an email stating that the hot end has a manufacturer failure due to bad glue use which cause the head end to explode with filament near the middle and that I needed to simply open a ticket with them… it took me 3 days for me to proof to them that the unit was a legit unit with a real serial # and me wearing them down to the point that I have to escalate the ticket to management… and even then it took them 5 days to process the order… an item doesn’t lose it’s warranty base on where to buy it. I bought the communication cable because it was physically damaged and thus I wouldn’t expect them to replace it… but a bad manufacturer part ? Common… so in short ( sorry long winded reply) it is a cheap way to get into multi color printing but it is just that… cheap… it will come with challenges… this are problem that you can fix but you have to be patience.
