Based on replicator dual is what i said.
All the different clones have variations.
The knp is one of the highest quality around.

Nozzle ooze is no different than my flashforge creator. Extryder setup is standard, no innovations I can see.

But Like I said - great build quality :-)
And stupid value for money at the current price.

At the end of the day it's an unenclosed replicator pro for the price of a plywood ctc creator standard that will, most likely, not work.
