How do I adjust steps/mm on UM2?

All my parts are coming out a little too big. They are good in Cura, but the print is 2mm too big.

Where should I look on the UM2 to adjust the steps/mm?

Thanks in advance,

The steps per mm setting is a function of the motor, pulleys and belts. While there can be other factors at play for the extruder, you really shouldn't need to adjust the steps for the x and y axes.

You can get some shrinkage as the plastic cools, and there can be some other things going on that leave the final part fractionally too small, depending on its geometry. But 2mm sounds like a lot. Can you provide some examples of what you are seeing?
