I have a Prusa i3 MK3 or maybe it was upgraded to a i3 MK3S.

How can I figure out?

The description of the upgrade kit talks about

  • the SuperPINDA (how is it different from the old one?)
  • a number of small changes (which?)
  • improved plastic parts (which parts, how are they different?)
  • metal clips (where to look for them?)
  • a number of minor changes to the extruder plastic parts (which ones, before and after?)

I'd like to figure that out without taking the printer apart.

Filament sensors

The MK3 has 4 pins on the filament sensor, the MK3S has only 3 pins. While you need to take the extruder apart to see that, you can also have a look at the cable instead:

Filament sensor cable

Matching the sensor, the MK3 has a 4 strand wire including blue and the MK3S has a 3 strand cable without blue.

Bearing clips

Looking under the heatbed, you'll find the MK3 bearings are fixed with U-bolts while the MK3S has broader bearing clips.
