Step 1 Introduction

⬢Some parts on your printer can be used for upgrading, it is essential to check their condition before you start upgrading. This chapter will guide you through the visual inspection of all these parts. If you find a part in poor condition, you have plenty of time to order a new one and continue using the printer in the meantime.

Do not disassemble or disconnect anything until prompted.

The following instructions use the MK3S+ printer as an example. Some parts may be slightly different from previous models.

⬢Any parts that are found to be in poor condition during the inspection can be replaced with new parts. Everything is available in our eshop.

Please note that you have to be logged in to access all parts.

Step 2 Preparing the printer

⬢Before start handle the printer, make sure that:

⬢Z-axis is at least at the top level of the PSU.

To access the Z-axis movement menu, you can use the quick shortcut of long holding the knob (1 second), then rotating to move the axis.

⬢Filament is unloaded from the extruder.

⬢Spool holder is removed from the printer.

⬢Print sheet is removed from the heatbed.

⬢Printer is turned OFF and the power cable is unplugged from the PSU (power supply unit).

Step 3 Heatbed inspection

The upgrade from MK3S/MK3S+ to MK3.5S is compatible with the heatbed that has screwed power cables.

⬢From the underside of the heatbed, take a closer look at the heatbed connector and check what variation you have:

⬢THREE SCREWS in a row: heatbed with screwed power cables. This variation is compatible with the upgrade.

⬢ONE SCREW: soldered power cables. This variation is NOT compatible with the upgrade. You can buy a compatible version in our eshop

Step 4 Heatbed surface inspection

⬢Carefully inspect the surface of the heatbed. If you find any major scratches (up to the copper layer) consider replacing it with a new piece.

Step 5 X-axis smooth rods inspection

⬢Wipe the dirt from the entire length of the smooth rods with a paper towel.

⬢Carefully inspect the surface of the smooth rods up close.

⬢The surface must be clean, smooth, and without corrosion.

⬢If you find a rough scratch, corrosion, or rough surface, it is highly recommended replacing with a new piece. Buy a new Smooth rod X-axis (8x370 mm) in our eshop

⬢Likewise, if the smooth rods are scratched or the bearing travel on the rods is not smooth (they really stutter), we recommend ordering new LM8UU bearings as well. Buy new LM8UU bearings in our eshop.

Step 6 Y-axis smooth rods inspection

⬢Wipe the dirt from the entire length of the smooth rods with a paper towel.

⬢Carefully inspect the surface of the smooth rods up close.

⬢The surface must be clean, smooth, and without corrosion.

⬢If you find a rough scratch, corrosion, or rough surface, it is highly recommended replacing with a new piece. Buy a new Smooth rod Y-axis (8x330 mm) in our eshop
