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!

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.

⬢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.

⬢A correct height of the SuperPINDA sensor compared to the nozzle should be similar to the last picture.

⬢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.

⬢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.

⬢Put the steel sheet back and clean it with IPA to remove dust and grease.

Re-run the first layer calibration until you are satisfied with the results.
