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.

Hi and welcome,
First of all be aware that new versions of the firmware have been deployed since september, maybe it's worth updating?
From what i know stepper motors can reach 80°c and indeed when they heat up steps can be skipped, i'm not really aware of problems of overheating motors on the Ultimaker 3, are doing anything special?
Enclosure?
High Bed temperature?
Ambiant temp of the room?
