I finally found out the problems were happening because the lift switch was not calibrated properly causing the print head to press on the switching bay way too hard. This thus caused the Y axis to skip.

After tightening the pulleys most of the skipping issues were gone except the one problem to where the 2nd layer and so on are offset by 2mm on the Y axis.

I always kept the printer in a cabinet and the only skipped steps that I experienced were that on only every time I did dual color prints on PLA (200c Nozzle, 50c Bed, Also single extruder prints came out fine) the first layer was always off by around 2-3 millimeters. The one time I printed something outside the cabinet it skipped really badly on the y axis. I'm currently doing a 10+hr print single color print so when its done I will update it and attempt another dual color print and see how it comes out.

OK so I received my Ultimaker 3 in late may 2017 and i never updated the firmware around early September. After the update I noticd that the printer was significantly louder and thought it was normal. Just recently I checked how hot the steppers were because when I first got my ultimaker I remembered the steppers got warm on long 10+ hr prints. To my surprise the motors were too hot for comfort. I measured the temp with a multi-meter it it measured at 55 degrees Celsius. I have also been getting skipped steps which i'm starting to think is somewhat related to how hot the motors are getting.
