This is it! The final installment of our Prusa i3 MK3S+ build guide. All that’s left to do is plug in all the cables and run some calibrations and the 3D printer will be ready for action. A video version of the build guide is linked below on our YouTube channel.
Many have trouble with the wiring process so I have attempted to highlight as well as possible where all the connectors plug in.
I hope this has been useful to those that have used this as a supplementary guide to assist with assembling your Prusa MK3. I’ll have more next week. Happy printing!

Now that the 3D printer is fully assembled and the Preflight check is complete, you can run through the calibration process. Plug the printer into mains power and turn on the switch. You’ll be prompted to run the automatic calibration sequence which takes around ten minutes and is super simple. The final step is the Z height calibration shown in the video below.
