⬢For the following steps, please prepare:
⬢Side panel (2x)
⬢M3x8rT screw (20x)
The side panels are symmetrical, it doesn't matter which one you use first.
⬢Turn the left side of the printer towards you.
⬢Add the side panel onto the printer’s frame.
⬢Align all cover-clips with the openings on the side panel.
⬢Insert M3x8rT screws into all the openings. Before you start tightening them fully, ensure all edges of the panel are properly aligned. Then, tighten up all the screws using the T10 screwdriver.
You can use 1.5mm Allen key inside the openings to adjust the cover-clips alignment slightly.
⬢Tighten the top metal cover clip to the frame from the inside, using the T10 screwdriver.
Use the same exact technique to attach the side panel on the other side of the printer.
⬢Turn the right side of the printer towards you.
⬢Add the side panel onto the printer.
⬢Insert M3x8rT screws into all the openings. Before you start tightening them fully, ensure all edges of the panel are properly aligned. Then, tighten up all the screws using the T10 screwdriver.
⬢Tighten the top metal cover clip to the frame from the inside, using the T10 screwdriver.
⬢It's time for another gummy bear. Take it!
Did you know that in 1981, the Haribo company, which was founded by Hans Riegel, introduced gummy bears to the United States?
ATTENTION: Make sure your workspace is clean before you start working with the heatbed. Use a soft pad underneath (cloth / cardboard) to avoid scratching the heatbed components.
⬢Turn the heatbed upside down.
⬢Undo the four marked screws holding the bed-controller-case.
⬢Take the cover off.
Don't throw the parts away. You will need them later on!
⬢Remove the four power terminal screws using the Phillips screwdriver. Keep them aside as we will need them in the next step.
⬢Insert the heatbed into the center of the printer as in the picture with the terminals facing down. Keep it in an upright position. Make sure the heatbed cables are accessible below it.
⬢Prepare the power connectors into the indicated layout. Keep the printed part on.
⬢Red (+ / positive) wires are closer to the center.
⬢Black (- / negative) wires are closer to the sides.
⬢Connect the data cable to the center connector.
⬢Attach the power connectors into the terminals and fix them in place using the previously removed screws and the Phillips screwdriver.
Double check you have connected the power cables correctly!
⬢Re-attach the bed-controller-case.
⬢Fix it in place by tightening the four screws using a T10 screwdriver.
⬢Take off the linear rail stoppers on both inner sides of the printer.
You might have more than two rail stoppers in both bearings. Pull all of them out from the rail.
⬢Take the Heatbed and attach it to the top of the threaded rods. Both of the trapezoid nuts on the sides must engage onto a threaded rod.
Pay attention to the connected cables while you are attaching the Heatbed!
⬢Using your hand, rotate the threaded rods slightly until both of the rods engage into the nut on the side of the Heatbed.
⬢The Heatbed should now hold onto the threaded rods.
⬢By rotating the threaded rods on both sides, move the Heatbed approximately 5cm below the top of the threaded rods.
Make sure the Heatbed is always as leveled as possible while you are moving it by rotating the threaded rods with your hand.
⬢For the following steps, please prepare:
⬢Z-Axis bearing housing (2x)
⬢Bearing (2x)
⬢M3x10 screw (4x)
⬢Slide both bearings into the Z-Axis bearing housings.
⬢
Move the HB M3nEs nuts towards the linear rail on both sides of the printer.
⬢Install the Z-Axis bearing housing onto the M3nEs nuts.
⬢Insert two M3x10 screws and tighten them using the 2.5mm Allen key.
Repeat the same process for the other side too.
⬢For the following steps, please prepare:
⬢M3x12rT screw (4x)
⬢M3x20rT screw (2x)
⬢Take the left Z-axis part and slide it up to the heatbed frame.
⬢Fix it to the heatbed frame with two M3x12rT screws using the T10 screwdriver. Don't tighten it all the way yet!
⬢Now, fix the right Z-axis part to the heatbed frame using the same technique.
⬢Now, tighten all four screws in a cross pattern:
⬢First, tighten the front right and rear left screws.
⬢Then, tighten the front left and rear right screws.
⬢Take a look inside the printer. We have to attach the cable chain onto the bottom of the heatbed.
⬢Locate the openings for the cable chain on the back of the heatbed frame.
⬢Attach the cable chain mount to the openings using two M3x20rT screws. Bend the cables slightly if needed.
⬢Tighten up the screws using the T10 screwdriver.
⬢Take two gummy bears. Finally!
Did you know that gummy bears have become a popular ingredient in various desserts, including cakes, ice creams, and even cocktails?
⬢Well done! You have just finished the Heatbed & Side panel assembly.
⬢Proceed to the next chapter: 5. Extruder & accessories assembly.
