Prints not coming out to shape desgined
My printer has bee working great but suddenly in the middle of a print it started printing egg shaped instead of perfect circles. The first photo shows how it started off perfect and at some point started egg shaping. The transparent color is hard to see so i printed it in black again and you can see the first layer is some what egg shaped. I've checked the belts they are tight, ive replaced the Y motor (i have a handful of 3d printers and tons of extra parts) I assumed it was the Y axis since its at the top and bottom of the circle. I have also checked all the wired ends on the rambo board are connected and they are all seeded in as they should be. it will also start printing then randomly stop as if a crash occured but start printing in a totally different spot as you can see in the last photo i tried printing a calibration cube out. it seems strange that it happend suddenly mid way through a print and now it happens every time i try to print. any help would be very much appreciated!

loose pulley on the motor

mine ended up being a loose screw in the middle of my heatbed that holds the belt on the underneath the Y bed frame. it was just ever so slightly shifting which made the prints skew. Also the Y pully was a tad bit loose so i torqued it down as well and now my prints are nice with the exception that my top layers now have pits in them which i have no clue as to why. It seems fixing one issue will cause 5 more issues.

In such cases, I first do a full check
