We are aware of that the full upgrade from Original Prusa i3 M2/S to MK3 is a little bit pricey, so we came up with the second best option - the MK2.5 upgrade. It gives you the best features of magnetic bed with spring steel sheet, whole new extruder head with Bondtech and Noctua fans goodness and also the P.I.N.D.A. 2 bed leveling sensor and filament sensor. 

But if you want the full MK3 upgrade anyway, no problem! You can find it here.

  • Bondtech extruder gears
  • Filament Sensor
  • P.I.N.D.A 2 with thermistor

You will not be able to use the previous version of the Multi Material Upgrade for MK2S with the MK2.5! You need to upgrade to MMU 2. For all owners of the previous MMU version, the price is set to 149 USD / EUR..

If you're upgrading from MK2, you will NOT get MK2S parts like u-bolts and new rods/bearings, you have to get them separately.

G-code files to print on your MK2/S will be available prior to the release in Prusa i3 printable parts  

You can check out what is new in the article on PrusaPrinters.org.
