XYZ Calibration failures... on fresh out of box pre-assembled printer  

XYZ Calibration failures... on fresh out of box pre-assembled printer

Understandably, I'm a little upset at present, I sent $250 extra to buy an assembled and tested printer... which doesn't seem to work.

This evening I pulled my new MK3 out of the box, followed the (rather out of order) instructions, powered it up to move the Z axis up (to make safe removal of the foam), removed the test print from the bed... then proceeded to run through the setup wizard.

First time I tried an XYZ calibration, I killed it quickly as the paper was getting caught by the nozzle, even poking a small needle sized hole through it.

Before the second time I got the nozzle nice & hot, removed the existing filament, and gave it a light cleaning. I could identify no further material sticking on the outside of the nozzle. It made it to failing on the second calibration point.

I noticed that one of the rear rubber feat was still in the box, so I put it back to where I thought it should go, along side the other rear foot on opposite rail. This time I made it to the third calibration point. An improvement? Not really.

For the fourth time, I broke out my camera to record the progress... and sure enough, come calibration point 2... it fails:

What am I supposed to do about this? The whole idea of buying a pre-assembled, pre-tested unit was to avoid these out of the box issues.

On a lark, before posting this I decided to upgrade from firmware v 3.3.1-845 to 3.4. No changed, next failure happened on point 2... still catching the paper, despite the nozzle being clean. Before the upgrade I was getting "XYZ calibration failed. Bed calibration point was not found.", this last time around I'm told to consult the manual for the failure.
