  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.

    • 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 the nozzle is touching slightly the heatbed. Don't bend the heatbed!

    • Don't place the steel sheet on the heatbed during the entire P.I.N.D.A. probe adjustment process. Wait for the XYZ calibration.

  2. Move the extruder carefully all the way to the right. Make sure that the nozzle is not scratching the surface during the movement! If it does, rise the right side of the X-axis by rotating the right Z motor slightly clockwise.

    • If an adjustment is needed, you can lower the nozzle height by rotating the right Z motor counter-clockwise.

  3. Move the extruder to the centre of the X-axis. Take a zip tie from the package and place it under the P.I.N.D.A. sensor. Use the middle part of the zip tie, not the tip. Release the screw holding the P.I.N.D.A. sensor and gently press it against the zip tie.

    • Tighten the screw on the P.I.N.D.A. holder again.

    • !!! DO NOT use glue to fix P.I.N.D.A. probe in the new type of holder with the M3 screw, you won't be able to release it again !!!

    • A correct height of the P.I.N.D.A. sensor compared to the nozzle should be similar to the last picture.

  5. Firmware updater is now part of the Slic3r PE. In case you have it already installed, you can skip to the next step.
    • Firmware updater is now part of the 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 opened for the next step!

    • Install drivers on your Windows, macOS or Linux system.

    • Part of the driver's package is Slic3r PE, which includes a tool for firmware upgrade.

  6. ATTENTION!!! MK3 and MK3S have a different firmware. You must upgrade!
    • ATTENTION!!! MK3 and MK3S have a different firmware. You must upgrade!

    • 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!

  7. Open Slic3r PE 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.
    • Open Slic3r PE 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.

  8. Before you leave Slic3r PE, please add the MK3S printer profiles!!! You can also remove those for MK3. From the top menu select Configuration -> Configuration Wizard Look for the MK3S option and select it.

    • Click Next, then Finish.

    • Expand the printer's menu and check if the MK3S option is present. If not, please repeat the process again.

  9. Put back the steel sheet and clean it with IPA to remove dust and grease. First, run the Calibrate Z to make sure the X-axis is absolutely level!

    • 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 P.I.N.D.A.

  10. See our free 3D Printing Handbook - prusa3d.com/3dhandbookMK3S
