  • This step goes over how to read our instruction guides.


  • ​General step instructions are in bullet points at the top of the step.


​🟪 Colored square match with colored markers in images to highlight steps.

  • Bullet points under a colored square step are additional information with the above step.


ATTENTION: If there is important info it will be put in a warning panel

🗈Tip: Some additional tips for steps will be highlighted with this tip box.

Note: While you should use the pictures to help with the assembly, there may be some differences between the pictures and what you have.

Step 2: Unboxing pt. 1 - Removing the Accessories

  • Cut the tape holding the top of the box in place and remove the lid.


🟪 Remove the Hub (small black box, and the included filament (Hatchbox PLA box) and set them to the side.

🟦 Remove the black foam sheets on top of the printer.

🟩 Remove the accessories box and set it to the side.


Step 3: Unboxing pt. 2 - Removing the arm

🟪 Remove the three cardboard tubes around the printer.

🟦 Pull the piece of cardboard at the top of the printer up and out.

  • The black foam at the top of the printer should be easy to remove now.


🟩 Remove the small cardboard tube to the back of the printer.

🟨 Holding the printer by the Z-axis rail, lift it out of the box.

❌Don’t lift the printer by the arm, circuit case, or other printed parts.

🟧 Set the printer down on its side as it was in the box.

Step 4: Unboxing pt. 3 - Accessories box

  • Open the Accessories box.


In the top layer of the box there is the following:

🟪 Power cable

🟦 Spool holder

🟩 Printer feet

🟨 Filament Guide

🟧 Homing block

  • There is also a small bag of parts.


  • Remove the top cardboard tray.


🟥 Below it is the bed and print surface.

Step 4: Tools Needed

2.5mm Allen Key

3mm Allen Key

5mm Allen Key

2- Leveling Feet

Step 1: Parts Needed

🟪 6 x Screw on Feet

Step 2: Attaching Feet

🟪 Look at the bottom of the arm section.

  • there are two threaded holes in the bottom plate.


  • Screw two of the feet into the holes.


🟦 Take the Bed section and flip it over so the frame is up.

⚠It is easy to scratch the PCB, so make sure both the PCB surface and table surface are clean first.

🟩 There are four threaded inserts on the corners of the frame.

  • Screw the remaining four feet into the inserts.


3- Joining Arm to Bed

Step 1: Preparations

🟪 flip the bed onto its feet.

🟦 Notice the four brackets on one of the long sides of the bed frame.

  • This is where the arm mounts to the bed.


🗈Make sure these brackets are pointed towards an open area of the table with enough room for the arm.

🟩 Look at the front edge of the arm frame.

  • There are two T-slot ends sticking out of this side of the frame.


  • The outer rails are what go onto the brackets on the bed frame.


Step 2: Sliding Bed onto Arm Mount

🟪 Take the arm section and stand it up on it’s feet on the table.

  • Line up the T-slots on the arm with the brackets on the bed frame.


  • Slide the arm section onto the bed.


At this point the arm may stand on it’s own but it is not attached yet, keep a hand on it until the screws are tightened.

🟦 Tighten the four set screws going into the arm frame.

  • The two screws next to the circuit case are difficult to reach, but you should be able to reach the top screw reaching down between the bed and the case, and the lower screw by reaching under the arm.


Step 4: Initial Leveling of Base

🟪 Look at the six feet under the arm.

  • Check to make sure they are all touching the table.


    • If one of the feet is floating, loosen it to lower it to the table, or raise the other feet


4- Wiring the Bed

Step 1: Parts Needed

🟪 Gather the thermistor wire.

Step 2: Removing Circuit Cover

🟪 Going to the circuit case, remove the four screws attaching the cover next to the bed.

🟦 Set the removed parts aside for now.

Step 3: Thermistor wire

🟪 Look at the corner of the bed with the red/black wires coming off it.

  • Notice that there is a connector next to these wires.


🟦 Take the thermistor wire and plug it into this connector.

  • The connector should be oriented so the clip on the thermistor wire is facing the table when you plug it in.


Step 4: Inserting wires into Circuit Case

🟪 Take the two cables from the bed.

  • Insert them into the circular hole in the side of the circuit case close to the bed.


  • Pull the cables in until there isn’t much slack outside the case.


Step 5: Connecting the wires


🟪 Looking at the Control board, notice the screw terminals on the side of the board closest to the Z-axis.

  • These terminals should be covered by a plastic lid. Flip the lid up.


  • The two terminals on the left should already be populated.


🟦 Loosen the two terminals on the right as much as possible without removing them.

  • The space for the wires is cramped so you will want as much room to slide the spade connector in as you can get.


🟩 Take the black wire from the bed and put it in the leftmost open terminal.

  • Take one of the screws and screw it down to the terminal, making sure it is pushed all the way in as you do.


  • Take the red wire from the bed and put it in the rightmost terminal.


  • Take the other screw and screw the wire down into the terminal, making sure it is pushed all the way in as you do.


🟨 Take the thermistor cable and plug it into TEMP_0 on the Duet board.

  • You can also refer to the circuit diagram below.


🟧 Thermistor

🟥 Bed heater wires

Step 6: Reattaching the circuit cover

🟪 Gather the cover and four screws you removed with it.

🟦 Reattach the circuit cover to the case.

  • Make sure no wires are pinched in between the cover and the edge of the case.


5- Filament Spool Holder & Guide

Step 1: Parts Needed


🟪 spool holder

🟦 filament guide


Step 2: Removing the top Z plate

🟪 Using the 5mm Allen key, remove the four screws holding the top Z Axis plate on.

  • Set the screws to the side.


🟦 Pull out the cardboard tube behind the ball screw.

Step 3: Inserting the spool holder

🟪 Take the Spool holder.

  • Notice that one end of the part has a hook on it.


🟦 Take the Z axis top plate.

  • Notice there is a slot in the plate.


🟩 Taking the two parts, insert the hook of the spool holder into the slot on the top plate.

  • The end of the hook should be on the same side of the plate as the other printed part that was already screwed onto the plate.


Step 4: Mounting the top Z plate

🟪 Place the top plate back on the top of the Z axis.

  • The hook on the spool holder should go into the hollow center of the Z Axis.


  • The cylindrical part should go back over the ball screw.


🟦 Take two of the M6 screws you removed with the top plate and thread them into the back two holes.

Step 5: Attaching the Filament Guide

🟪 Take the filament guide and the other two M6 screws that were removed with the top plate.

  • Insert the two screws into the two countersunk screw holes on the filament mount.


  • Screw the filament guide into the front two holes on the top plate.


  • Tighten the four screws with the 5mm Allen Key.


6- Homing Plate

Step 1: Parts Needed


🟪 Homing mount

🟦 2x 10mm M4 screws

Step 2: Attaching the homing plate

🟪 Notice that there are two T-slot nuts in the bottom rail of the bed frame on the opposite side of the arm from the circuit case.

🟦 Insert the two screws into the homing mount.

  • Align the T-slot nuts with the screws.


  • Attach the homing block to the T-slot nuts using the 3mm Allen key.


🟩 Align the edge of the homing block with the edge of the bed.

  • Tighten the two screws with the 3mm Allen key.


7- WiFi Antenna

Step 1: Attaching the WiFi Antenna

🟪 Take the WiFi Antenna.

🟦 Look at the side of the circuit case, there is a brass threaded port on the side.

  • Screw the antenna onto the port.


This does not have to be attached tightly, just hand tightened.

8- Print Surface

Step 1: Placing the Print Bed

🟪 Gather the print surface

🟦 Place the surface on the magnetic bed with the desired texture facing up.

  • Push the surface so the edges of the surface align with the edges of the bed.


9- Power Cord

Step 1: Plugging in the printer

🟪 Take the power cable

🟦 Look for power switch on the back of the printer.

🟩 Plug the cord into the power switch.

  • Check that the switch is set to off before continuing.


Step 2: Printer Assembled!

  • Congrats! Your printer is ready for preflight checks. 🎉


  • Take a moment to compare your printer to the picture to make sure there aren’t any obvious issues.
