I have a Robo3d R1+ Plus and I love it. The only down side is that it is open but I haven’t had a problem with that, I still print abs and everything else under the rainbow all the time. Literally. Between here and Robo3d’s forum you can get questions answered in an hour. They also have great customer service! the build plate is something like 10" x 9" x 8" and sells at $799.99.
If you want to tinker there are plenty of upgrades due to it being open source.
The quality and reliability of the Mankati is not great. It is a nice machine for it’s price in combination with it’s specifications. The extruders are still a bit frustrating.
I tried to react at your other post but Hubs had a bug.
This was my answer about the ZYYX+:
I like the ZYYX+. I print daily with 2 of them and it’s a nice improvement on the ‘old’ ZYYX. The cooling is better and the X-Y construction is more stable. The extruder is still one of the most reliable extruders i ever worked with. The only issue i have is the navigation of the print-file-list on the machine can be a bit slow. And if you want to print a lot with ABS, it’s not the best choice. For strong parts i use Polymax or Colorfab XT.
Another issue can be it’s weight. I do many workshops and it’s a heavy machine.
I’m also happy with Simplify3D, it’s very nice to work with.
My perfect duo at this moment are the ZYYX+ (PLA, Polymax, PC, PET, TPU/Flex) and the Zortrax M200 (ABS, PCABS, HIPS, PET). Try to get a demo somewhere, it can help.
