The Original Prusa MK3 to MK4S Upgrade Kit is the full upgrade that also contains the MK4’s new X/Y precise motors (400 steps, 0.9°per step). It’s the most expensive of all three, but last time you voiced your interest in a full MK2->MK3 upgrade pretty strongly, so we decided to give you a full MK4 upgrade as well. :-)
This product is supplied as a kit - you must assemble it yourself!
