⬢Extrusion 3030 205 mm (2x)

⬢Printer frame (1x)

⬢M5x16r screw (16x)

⬢Take the LONGER extrusions and place them next to the frame.

Note: screws are inserted from the opposite side of the frame. If you need to manipulate with the frame, make sure the extrusions are on the correct side once again.

⬢Ensure you are using the correct holes closer to the center of the frame, see the second picture. Use the M5 screws to connect extrusions to the frame. Tighten the screws with the 3mm Allen key just slightly!

⬢Now, tighten the screws fully, but IN A DIAGONAL PATTERN, see the last picture. As soon as you finish tightening the first diagonal pair, tighten the second pair. Then proceed to the other long extrusion.

⬢Take the SHORTER extrusions and place them next to the frame.

Note: screws are inserted from the opposite side of the frame. If you need to manipulate with the frame, make sure the extrusions are on the correct side.

⬢Ensure you are using the correct holes, see the second picture. Use the M5x16r screws to connect extrusions to the frame. Tighten the screws just slightly!

⬢Now, tighten the screws fully, but IN A DIAGONAL PATTERN, see the last picture. As soon as you finish the first diagonal pair, tighten the other screws. Then proceed to the last short extrusion.

⬢Front plate (1x)

⬢Rear plate (1x)

⬢There is a silver label with serial number on the rear plate. Keep it in mind, we use it as a guide to orient the part later on. Do not remove the label!

⬢M5x16r screw (16x)

⬢M3nEs nuts (4x)

⬢Rotate the frame so the longer extrusions are facing towards you.

⬢Place the front plate (the shorter one) onto the extrusions and secure it with M5x16r screws, DON'T TIGHTEN them yet!

⬢Now, tighten the screws fully, but IN A DIAGONAL PATTERN, see the second picture. As soon as you finish the first diagonal pair, tighten the second pair. Then proceed to the other long extrusion.

⬢Turn the printer so that the shorter extrusions are facing you.

⬢Place the rear plate onto the extrusions and secure it with M5x16r screws, DON'T TIGHTEN them yet!

⬢Now, tighten the screws fully, but IN A DIAGONAL PATTERN, see the second picture. As soon as you finish the first diagonal pair, tighten the second pair. Then proceed to the other extrusion.

⬢Insert the M3nEs nut into the right short extrusion. Insert the side with the spring (metal plate) first.

⬢Push the entire nut inside the extrusion using your finger.

⬢Use this method for both M3nEs nuts. The exact position of the nuts doesn't matter at this time.

⬢The frame screw openings are drilled by a high-precision CNC machine. Uneven tightening during can slightly warp the frame assembly. It can be corrected though.

⬢Using your hand, try to wiggle the frame side to side to check whether some of the corners are lifting up.

⬢In case you find any imperfections, release the screws, press the extrusions against the FLAT SURFACE and tighten them again. Then check if the frame still rocks side to side, back and forth. Rotate the whole assembly 90 degrees and check again. Repeat the whole process if necessary.

⬢Antivibration foot (4x)

⬢Cable clip (6x)

⬢Turn the whole frame assembly onto the side and insert an antivibration foot into the bottom groove of the each extrusion. Insert and turn 90 degrees to lock it in place.

⬢Repeat this process for all 4 feet. Place them 1-2 cm far from the end of each extrusion.

⬢Turn the frame like in the picture and focus on the marked area

⬢Take one of the cable clips and hook the side with the clip into the inner groove of the lower longer extrusion. There is a hook on the part, see the detail.

⬢Place the other end of the clip on the underside of the extrusion.

⬢Use more force to push on the bottom side of the cable clip. It must fit into the groove and you must feel it "click" in.

⬢Install three clips to the long extrusion.

⬢Install one clip to the short extrusion.

⬢Turn the frame, install two clips to the second short extrusion.

⬢Have a look at the right side of the frame and locate the M3nE nuts. Insert M3x10 screws into them. Turn them only 3-4 times by using a 2.5mm Allen key, just for the screws to be kept in place.

⬢Take the PSU and place it above the screws. Adjust the M3nE nuts so they line up with the grooves on the bottom of the PSU's case.

⬢Slide the PSU down onto the screws. Screw them in some more, but don't tighten them firmly yet - we need the PSU to be able to move slightly so we can adjust its position in the next step!

The screws should be able to hold the PSU in a "vertical" position for now.

⬢Now have a look at the frame from the front side. Verify the PSU is on the right back side of the frame when looking from the front.

⬢Insert M4x10r screws into the holes in the frame, towards the front of the PSU.

⬢Adjust the position of the PSU, there are holes in the PSU's case, which must align with the holes in the frame. By default the PSU sits slightly lower than needed, pull it up little bit. until the M4 screws are able to catch the thread in the PSU.

⬢Make sure the PSU is pressed against both the frame and the extrusion on the bottom.

⬢Everything aligned? Tighten the M4 screws up using the same 2.5mm Allen key.

⬢Now, tighten up the M3 screws on the bottom.

⬢xBuddy box (1x)

⬢Thermal pad 40x12x2.2 mm (1x)

⬢Thermal pad 12x12x2.2 mm (2x)

⬢M3x10 screw (2x)

The list continues in the next step...

⬢xBuddy board (1x)

⬢Zip tie (4x)

⬢X-holder (1x)

⬢Insert four M3x6 screws to the back of the frame (side with shorter extrusions), so they resemble a rectangular pattern. Tighten the screws fully into the frame to clean the threads. Then loosen the screws, leaving a gap of at least 3 mm between the screw head and the frame.

⬢Insert two M3x10 screws into the M3nE nuts in the second short extrusion. Turn them only 3-4 times by using a 2.5mm Allen key, just for the screws to be kept in place.

⬢Attach the xBuddy box on the M3x10 screws in the extrusion. Do not tighten the screws at the moment!

⬢Slide the xBuddy box to the frame and attach the box to all 4 screws in the frame. The screws must fit into the top part of the "key" hole. See the detail.

⬢Fully tighten all four M3x6 screws to secure the xBuddy box.

⬢Fully tighten both M3x10 screws in the M3nE nuts.

⬢Peel off the white protective layer from all thermal pads.

⬢Attach the pads onto the back of the xBuddy board. There are markings that indicate the correct size and positions.

⬢Peel off the blue protective layer from all thermal pads.

⬢For better access to the xBuddy box, carefully place the frame on the side with the PSU.

⬢Insert the xBuddy board into the xBuddy box. Before fully attaching it completely, center the holes in the board with the holes (columns) in the xBuddy box

⬢Make sure the Ethernet connector is properly inserted into the hole in the xBuddy box.

⬢Fix the position of the xBuddy board by inserting five M3x6 screws. Do not fully tighten the screws. A few turns are enough for now.

⬢Fully tighten all five screws. But very carefully, otherwise you can damage the electronics board.

⬢Take a closer look at to the xBuddy box. There are four perforations on the metal case.

You can place the frame on the PSU side for better access to the xBuddy box.

⬢Use the X-holder as a zip tie guidance. Place the X-holder behind the lowest perforation like in the picture. Push the zip tie through the protrusion to the X-holder. Keep protruding 3 - 5 cm of the zip tie from the perforation.

⬢Use this procedure for all four protrusions.

⬢Place the printer back on its "feet".

⬢Insert two M3nS nuts into the Y-belt-idler.

⬢Y-motor-holder (1x)

⬢Thermal pad 25 x 25 x 1.2 mm (1x)

⬢M3x18 screw (3x)

⬢M3x10 screw (2x)

⬢M3nS nut (2x)

The list continues in the next step...

⬢Insert the M3nS nut into the corresponding openings on the top side of the Y-motor-holder. Using the Allen key, push the nut all the way in.

⬢Insert the M3nS nut all the way into the part from the side.

⬢Place the Y motor like in the picture. Use the motor cable as a guide.

⬢Attach the Y-motor-holder onto the Y motor and join both parts together with three M3x18 screws.

⬢There is a flat part on the motor shaft. Rotate the shaft, so the flat part is facing you through the opening in the Y-motor-holder.

⬢Attach the pulley on the shaft and ensure that one of the grub screws is facing the flat part of the shaft. Do not tighten the grub screw yet.

⬢Put one of the Allen keys on the MOST TOP surface of the printed part, like in the picture. And align the pulley with the Allen key.

⬢When the pulley is aligned, tighten the grub screw in the pulley against the flat part of the shaft. Then rotate the pulley and tighten the second grub screw.

⬢Peel off the white protective film from the thermal pad 25x25x1.2 mm.

⬢Stick the thermal pad on the Y motor and peel off the second protective layer from it.

⬢Place the Y-motor-holder onto the inner side of the rear plate of the frame.

⬢Ensure the correct orientation. The pulley must be facing towards the PSU.

⬢Attach the Y-motor-holder by using two M3x10 screws.

⬢To keep the Y motor cable safe during the assembly, temporarily hide it in the extrusion on the xBuddy box side.

⬢Compare the final look of the assembly with the picture.

⬢So that was an easy start, wasn't it? Good job anyway!

⬢Now, let's play with the next chapter: 3. X-axis & X-carriage assembly
