This is the first failed print that Ive had that i cant pinpoint an issue with. It appears that the layers have shifted (left) becasue they are still laying horizontal. At first i thought the whole top just drooped over. Obviously the top is supposed to form a tapered point...any ideas? Right now im thinking overheating with the board...
Interesting can you post a picture from the other side?
Interesting..... to say the least, looks too smooth to be motor step loss??? maybe pulley slip on the stepper.... but yes different picture views could show it better.
Maybe put a fan on your stepper drivers.

I was just thinking the same thing loose set screw allowing minor rotation on the shaft?
Yeah, it looks like a soft-serve ice cream machine print

Where is this set screw located? And if this was the issue would it show up in other prints? Im making a stand for a firework right now and it has a cylindrical part similar to the rocket that is coming out okay.
Here's more pictures

I thought the same thing! I laughed out loud as soon as i saw it.
The set screw inside the collar of the toothed pulley directly on the stepper motor shaft
? which direction is that sliding towards? the back of the printer or side?

Or any other pulley that is driven by a shaft. I'd have to say that is one of the coolest faults I have seen. I sure hope you figure this out and let us know what you find.
Yeah I thought about the other shafts but the X and Y stepper motors would be the most likely candidates.

+1 but as long as your there check them all.
Should they be loose or snug or as tight as i can get them by hand? Also, is it normal for the pulleys on the front end of the y axis to not have set screws? The left and right side are both missing them so im assuming its supposed to be like that (?)

Im fairly certain it was sliding to the left. I took it off the glass without taking note but if my memory is correct it was going towards the left side. This would indicate that the x axis set screws were lose if that is the problem correct?

Disregard this. It makes sense why there would not be set screws on anything but the motors now...

Don't forget about the ones on the cross shaft in the rear of the printer.

Just snug them up you don't want to mar up the shafts to badly.
Roger, thanks for the help guys! Ill probably try another one to make sure it wont happen again
Hey Adam, The front pulleys do NOT have screws, this is normal as they are just idler pulleys.

Toward her G spot 
It looks as if it were designed like that. Still a good looking print otherwise.
