⬢There's a hole in the extrusion that the pin has to fit into.

⬢Check that the pin fits into the hole in the extrusion

Repeat this alignment check always, when you will be assembling extrusions together throughout this manual. Improper alignment will cause visible gaps between extrusions.

The protrusions are designed with an overlap to ensure strength and accuracy when tightened properly.

⬢Turn the right side (no sticker) of the base towards you. Use the extrusion plastic cap as a guide.

⬢Make sure one profile insert is slid all the way to the back.

⬢Before you connect the extrusions together, see the protrusion in the "standalone" extrusion. This part must be aligned with the "groove" in the base extrusion. See the bubble in the third picture.

⬢Take one rear extrusion prepared earlier and slide its pin into the profile insert. Mind the correct orientation of the extrusion (protrusion vs groove).

⬢There might be a slight gap between parts, we will address this in the next step.

⬢Insert two M4x12 screws, from opposite sides of the extrusion.

Tighten the screws until you reach the surface of the metal plate, then stop! We will do the final tightening later on using the torque indicator.

⬢Use the longer side of the 3mm Allen key and tighten the M4x12 screws on both sides.

⬢Let's assemble the second rear extrusion. Turn the left side (with the safety sticker) of the base towards you and focus on the rear side. Use the extrusion plastic cap as a guide.

⬢Make sure one profile insert is slid all the way to the back.

⬢Insert the Z-Axis-back into the profile insert in the back of a base.

⬢Insert two M4x12 screws from opposite sides of the extrusion.

Tighten the screws until you reach the surface of the metal plate, then stop! We will do the final tightening later on using the torque indicator.

You have received two Z-axis assemblies, pay close attention to each assembly:

⬢Z-Axis fixed: This assembly doesn't rotate. Instead, it's held in place with screws. You'll notice these screws holding it in place. This Z-axis assembly will be installed first on the left side of the printer.

⬢Z-Axis rotary: This assembly rotates and has a single bearing in the middle, which is visible and allows the axis to rotate smoothly. This Z-axis assembly will be installed as a second on the right side of the printer.

⬢Stay on the left side of the base. Use the safety sticker as a guide.

⬢Now, let's install the Z-Axis fixed in the cutout on the left side.

⬢Align the second profile insert with the opening.

⬢Guide the Z-Axis fixed motor cable through the opening in the base.

⬢Carefully insert the Z-Axis fixed with the cable into the base frame. The motor must perfectly fit into the opening and the pin on the extrusion must fit into the profile insert.

⬢Insert two M4x12 screws, from opposite sides of the extrusion.

Tighten the screws until you reach the surface of the metal plate, then stop! We will do the final tightening later on using the torque indicator.

⬢Use the longer side of the 3mm Allen key and tighten the M4x12 screws on both sides.

⬢Turn the base, so that the right side (no safety sticker) is facing towards you.

⬢Now, let's install the Z-Axis rotary into the opening on the right side.

⬢Align the second profile insert with the opening.

⬢Guide the Y-Axis rotary motor cable through the opening in the base.

⬢Carefully insert the Z-Axis rotary into the base frame. The motor must perfectly fit into the opening and the pin on the extrusion must fit into the profile insert.

⬢Insert two M4x12 screws, one from opposite sides of the extrusion.

Tighten the screws until you reach the surface of the metal plate, then stop! We will do the final tightening later on using the torque indicator.

⬢Use the longer side of the 3mm Allen key and tighten the M4x12 screws on both sides.

⬢Insert the 3mm Allen key into the torque indicator.

⬢Put on the Allen key handle from the other side.

⬢The assembled torque indicator looks like this.

The protrusions are designed with an overlap to ensure strength and accuracy when tightened properly.

⬢Tighten the screw till you reach the "OK" line and the 3mm Allen key is slightly bent.

⬢Proceed the same way on all eight M4x12 screws inserted in the extrusions.

Do not throw the torque indicator away, you will need it in the next chapter.

Starting in September 2024, you may receive a new injection-molded xLCD cover.

⬢Injection molded xLCD assembly (1x)

⬢M3x10 screw (2x)

⬢Older versions:

⬢Printed xLCD assembly (1x)

⬢M3x16 screw (2x)

⬢xLCD PE cable (1x)

⬢xLCD cable (1x)

⬢M3x10 screw (2x)

⬢Locate the M3nEs nuts in the front base extrusion and position the xLCD assembly in front of them.

⬢Insert the M3x10 (or M3x16 for older versions) screw into the right xLCD support.

⬢Use the 2.5mm Allen key to tighten the M3x16 screw into the M3nEs nut in the frame.

⬢Insert the second M3x10 (or M3x16 for older versions) screw from the left side and tighten it, but do not overtighten. The correct position of the xLCD assembly will be adjusted later.

⬢Align the xLCD approximately to the center of the base.

⬢Tighten the left M3x10 (older: M3x16) screw with the 2.5mm Allen key.

⬢Tighten the right M3x16 screw with the 2.5mm Allen key.

⬢Turn the printer to the left side so that the bottom of the base is facing you.

⬢Take a closer look at the rear side of the xLCD assembly and locate the PE Faston on the xLCD board. Slide the PE cable connector all the way onto the PE Faston.

⬢Turn the printer to the left side so that the bottom of the base is facing you.

Once in the corner flip the cables along the upper edge. See the picture.

⬢Insert the xLCD-cable-bottom-holder into the frame.

Make sure the cable loop is not too large.

⬢Press the xLCD-cable-bottom-cover into the extrusion.

⬢Guide the xLCD and the PE cables through the extrusion.

⬢Remove the rubber band from the Z motor cables.

⬢Insert the Extrusion cover 243mm. Push and slide it to the left.

⬢The extrusion cover has to be aligned with the end of the extrusion.

⬢Gently bend the cables over the corner and insert them into the extrusion. Start with the Z motor cable and then proceed with xLCD and PE cables. Gently bend the xLCD cable over the corner and insert it in the extrusion.

⬢Attach the frame-rear-cover on the printer. Make sure it perfectly fits on the extrusions.

⬢Secure it with the M3x10 screw.
