Prove me wrong

So far i can only get 20cm cubes to print. And it is the x-y-z cailbration cube with my x-axis all wiggly. Show me something that you print using at least 250cm x 150cm by 150 cm to prove that this printer can do what it was promised to do.

You show me that then I will quit complaining and fix this myself.

No matter how much I clean the bed with alcohol, or put tape down or put sticky stuff down, everything always pops off.

I have cleaned out the extruder tip, tried new tips, adjusted the temperature of the default blue and red (temp from 190 to 210 in 3° increments) even though they showed up brittle as crap I get nothing but spaghetti out of this printer.

I have lost a power supply, I had the short hot end leads, I didnt get the correct guides. I mean nothing has worked or been on my side. The dual extruder, wow, what a P>O>S.

Please help me to get the $395 worth out of this printer. I will gladly sell this to someone for $300 and include my extra 3 rolls, two of which havent been opened. I paid for every extra that I could, and I still lost money and time. I wish I had spent it on a Prusa.

And on top of that, where is the MakerTech support? They say let the community solve it, then they dont have to do anything.
