This is really frustrating.

Brand new CR-6 SE just grinds the entire print head against the glass for about a minute and then spits out a 202 error.  I flipped the glass over because it was starting to get a divot and it does the same thing.

Considering boxing it up and sending it back to the store.

What is wrong with this printer?

DERP.

There was a cable unplugged on front of the left leg of the gantry.  The install guide calls it the "photoelectric switch wire".  Probably means the photosensor was disconnected, so the Z axis had no way of telling how far away the printing platform is.

@sully1570 when you take of the housing from the hotend you will find a potentio meter 

now take a kitchen scale and let the gantry come down on the scale till you got 125 grams then trim the potentiometer to just the led lite up

@johan-jorez can you direct me to a detailed calibration for the 125 gram force calibration?
