Ok, so I will add our Ekocycle Cubify 3D printer issues here with the hopes that it helps.
The very first print we made was a dual extrusion white and red test cube. It printed white and red no problem. Later we tried the white for something and it printed lousy and then not at all. The kids assumed it was a plugged nozzle and of course our resident expert took it apart. I called Cube and they sent me another white under warranty. Last night we got it and installed it and...nothing. White still does not print. On a whim, we stuck it on the left side where the red has been printing the whole time and bada boom bada bing! White prints! Of course the result was less than we desired and it was at 9 pm on bagging day so we gave up on our hopes of a new Axis camera mount. I sent Cube another email stating what happened and am now waiting their response.
On the other hand it has proven how valuable a 3D printer is to our team. We are almost out of red filament and we have only owned this thing two weeks. One team member is already drafting plans for a DIY 3d printer, either a Prusa i3 or a Delta.
I will say I have been surprised that Cube has been very responsive and very fast on getting us a new roll of white. I contacted them after submitting a warranty claim form to find out how many weeks it would be and they said "You should see it tomorrow, we already sent it.". And it did show up fast.
