How to upgrade your PRUSA MK4 into an MK4S | Step By Step Guide!

Thanks for this. My upgrade kit just came in a few hours ago. There was a bit of deja-vu, as I built a Mk3s and my present Mk4 from kits - which I HIGHLY recommend as one gets valuable insights into the working of the beastie.

I have a MK4 that I upgraded from a MK3S+. Will this kit work on this since it was already upgraded? Also, will the MK4 nozzles work on the MK4S? I ask because I have two brand new nozzles I purchased for the MK4. Thank you.

Does the upgrade affect the connectivity to Prusa connect? As in affter the software flashing?

Thanks for your comment! Yes you will have to add your printer to Prusa Connect again as it will have a new serial number. This can be done using NFC through the Prusa app. You can read more about the app here help.prusa3d.com/article/prusa-mobile-app_735711
