Very good adhesion of every material I've printed.
Super satisfied. Feels like premium machine and prints with great quality.
Amazing printer.
I've had the printer for a week or so right about now and I've been using it non stop, I've had no issues and this has been the best experience with a 3D Printer with how headacheless it has been and how seamless and easy it is to use the printer.
Plus having the "built-in" multi color printing is amazing and for a great price.
Hopefully I won't be having any problems with this printer!
The printing side is genuinely good. CoreXY, 350x350 bed, and network printing straight from the slicer works - no USB sticks, no switching LAN mode. Parts come out dimensionally accurate, including printed threads standing upright and load-bearing parts in PETG-CF.
Two things keep it from five stars. Filament jammed in ACE slots 2 and 3 - it looks like heat creep after the material sits parked in the path for a while. And the nozzle clogged so badly that nothing cleared it: cold pulls, needle, heat soak, none of it worked, so a replacement nozzle is the only way out.
Still worth it overall. Just budget for spare nozzles and don't leave filament sitting loaded in the ACE.
Used this on a Kobra S1 Max (0.4 nozzle, 0.20 mm layers) for a set of load-bearing parts: a 465 mm arm, pivot pins and printed M14x3 screws and nuts. The printed threads came out standing upright without supports and the screws actually thread into the nuts - that only works if the filament is dimensionally consistent, so that says a lot.
No clogs, no bed adhesion issues, dimensions matched the model. Parts are noticeably stiffer than plain PETG, which is exactly why I picked the CF version for a part that carries load all day.
Happy with it - will buy again for outdoor and structural prints.
