Step 1 SuperPINDA adjustment (part 1)

Ensure the printer is turned off and not plugged in.
While moving with the extruder, the X-axis motor works as a generator. You will create a small amount of electricity and the LCD might flicker. Move with the extruder reasonably slowly and in the future always use the printer's controls.
Move the extruder manually all the way to the left.
By rotating BOTH threaded rods at the same time on the Z-axis move the nozzle until you reach the heatbed. Try rotating both the rods equally!
Check again from a different angle that the nozzle is touching the heated slightly. Don't bend the heatbed!
Don't place the steel sheet onto the heatbed during the entire SuperPINDA sensor adjustment process. Wait for the XYZ calibration.

Move the extruder carefully all the way to the right.
Make sure the nozzle is not scratching the surface during the movement! If it does, raise the right side of the X-axis by rotating the right Z motor (threaded rod) slightly clockwise.
If an adjustment is needed, you can lower the nozzle height by rotating the right Z motor (threaded rod) counter-clockwise.

Move the extruder to the centre of the X-axis.
Take a zip tie from the package and place it under the SuperPINDA sensor. Use the middle part of the zip tie, not the tip.
Release the screw holding the SuperPINDA sensor and gently press it against the zip tie.
Tighten the screw on the SuperPINDA holder again.
!!! DO NOT use glue to fix the SuperPINDA sensor in the new type of holder with the M3 screw. You won't be able to release it again !!!
A correct height of the SuperPINDA sensor compared to the nozzle should be similar to the last picture.

Step 4 Download the necessary software

Firmware updater is now part of the PrusaSlicer (previously Slic3r PE). In case you have it already installed, you can skip to the next step.
Go to prusa3d.com/drivers and select the MK3S printer.
Find the driver section and download the latest package. Leave this page open for the next step!
Install drivers on your Windows, macOS or Linux system.
PrusaSlicer (previously Slic3r PE) is a part of the driver's package. It also includes the tool for firmware upgrades.

Step 5 Download the new firmware

ATTENTION!!! 
Firmware for MK3 is different from MK3S+, you must perform an upgrade.
Firmware for MK3S is the same as for MK3S+. Just make sure you are running version 3.9.2 or newer.
Download the zip file with the firmware for the MK3S+ to your computer and unzip it.
To flash the firmware, the printer must be plugged and turned on!

Step 6 Updating firmware using PrusaSlicer

Open PrusaSlicer and from the menu select Configuration ->Flash Printer Firmware
Connect the printer to your computer using the bundled USB cable and select it from the menu. Hit Rescan if the printer is not on the list
Select the firmware file on your harddrive (.hex). Do not place the firmware on a network share.
Hit the Flash button.
Wait until the process is completed. You can click on "Advanced: ..." to see the flashing process including detailed log.
When the flashing process is done, you will be informed.
We're done here! Your printer is ready to rock ;)
In case of issues with flashing the firmware please visit our troubleshooting article.

Before you leave PrusaSlicer, please add the MK3S & MK3S+ printer profiles!!! You can also remove those for MK3.
From the top menu select Configuration -> Configuration Wizard
Look for the MK3S+ option on the Prusa FFF printers list and select it.
Click Next, then Finish.
Expand the printer's menu and check if the MK3S & MK3S+ option is present. If not, please repeat the process again.

Step 8 Calibrate Z and 1st layer calibration

Put the steel sheet back and clean it with IPA to remove dust and grease.
First, run the Calibrate Z to make sure the X-axis is absolutely level!
Then run the 1st layer calibration as we moved with the SuperPINDA.
Re-run the first layer calibration until you are satisfied with the results.
