The X2D is Bambu Lab’s enclosed CoreXY machine with a dual-nozzle toolhead: one nozzle prints the model, the other handles supports or a second material, and a gear-driven switching mechanism moves between them. That’s a different setup from the single-nozzle X1 Carbon, and a different mechanism from the H2D’s dual-nozzle toolhead, so don’t assume steps or fault codes carry over between the three. This guide covers what’s confirmed for the X2D itself: unboxing, first power-on, and the checks worth doing before you commit to a real print.
What’s in the box
The X2D ships either as a standalone printer or as a Combo bundle with an AMS 2 Pro unit included. Both come with a tool case and a printed quick start guide. If you ordered the Combo, you’ll also have the AMS 2 Pro box, its spool holder assembly, and a PTFE tube kit to connect it to the toolhead. Set all of that aside until the printer itself is unpacked and the transport fixtures are out.
Lift the printer out using the side handles rather than the frame or the acrylic panels. It’s not a light machine, so have a stable, level surface ready before you take it out of the box.
Removing the transport fixturing
Everything that kept the X2D’s moving parts still in transit needs to come off before you power the machine on. Work through it in order rather than skipping around, since some fixtures block access to others.
Start with the two lead screw fixtures on the Z-axis. Use the longer Allen wrench from the tool case to remove the screws marked in red, and pull off the accessories marked in green that lock the heated bed in place. Those screws sit in a recessed channel and can drop straight into the chassis if you’re not careful, so keep a magnetic screwdriver or a pair of tweezers nearby to catch anything that slips.
Once the lead screws are unlocked, pull down and remove the red plastic protectors from both of them. Then open the chamber and take out the desiccant packet and the tape holding it, along with the white protective film covering the inside of the side windows.
Cut the zip ties securing the linear rod, then gently pull the toolhead forward toward the front door. There’s another zip tie on the toolhead itself and a piece of foam behind the linear rod. Cut the tie, remove the foam, and peel the protective film off the toolhead. Because the X2D’s toolhead carries the nozzle-switching mechanism, check that nothing from the packaging, foam scraps, tape residue, zip tie remnants, is still caught around the switching lever or trigger arm before you move on. That mechanism has to swing freely for the printer to change nozzles correctly later.
Leave the foam block under the heated bed alone for now. It stays in place to protect the bed and can only come out after the first calibration cycle finishes, when the bed lowers to its final resting position. Pulling it early just means putting it back.
If you have the AMS Combo
The AMS 2 Pro unit has its own transport fixture and packaging foam along the inner chamber wall, plus protective film on its own window. Remove the screw marked in red to release its internal fixture, then lift the unit into place on top of or beside the printer according to the quick start guide’s diagram.
Take the spool holder assembly out of the accessory box, slide it into the base, and insert the PTFE tube holder into the slot on the spool holder. Connect the white PTFE tube between the spool holder and the AMS unit.
One detail worth flagging separately: if you plan to use the AMS 2 Pro’s filament-drying function with the X2D, it needs its own official switching adapter to power that feature. A standard connection to the printer alone won’t run the dryer.
Powering on and connecting the network
Once the fixtures are clear, plug in the power cord and switch the printer on at the rear switch. The touchscreen will walk you through initial setup, including network connection.
Connect the X2D to the same Wi-Fi network your phone or computer is on, not a guest network with client isolation turned on, since that will block the printer from showing up in Bambu Studio or the Handy app. If your setup includes a wired connection, Ethernet is also supported and tends to be more stable for a printer that’s going to sit in one spot permanently.
Register or sign in to your Bambu Lab account through the screen or through Bambu Handy on your phone, since cloud features, remote monitoring, and firmware updates all route through that account. Check for a firmware update as one of your first actions. Units that sat in a warehouse or on a store shelf for a while often ship with older firmware, and running the update before your first print avoids chasing bugs that were already fixed.
First calibration
After the network and firmware are sorted, the screen will prompt you to run the initial calibration sequence. This covers vibration compensation, bed mesh mapping, and extruder or flow calibration in one pass, and takes roughly ten minutes depending on which steps it runs. Let it complete uninterrupted. This is also the step that lowers the bed fully, which is your cue that it’s safe to pull the foam block out from underneath it.
Watch the bed visually during this process if you can. You’re not trying to verify the mesh data itself, that’s handled automatically, but a visual check catches obvious problems early: the nozzle scraping instead of hovering cleanly, the bed sitting crooked, or the gantry binding somewhere along its travel.
Mechanical checks before your first real print
With the machine powered off, move the toolhead along the X and Y axes by hand. It should travel smoothly with no grinding, no sudden stiff spots, and no unusual resistance from the belts. Press gently on the X and Y belts and confirm they feel evenly tensioned rather than slack on one side.
Check that the bed can move up and down along the Z lead screws without catching, and confirm the two screws you removed earlier didn’t leave anything loose or misaligned behind the gantry.
Because the X2D switches between nozzles mechanically during a print, cycle through a nozzle change from the screen’s maintenance menu once before your first real job, if that option is available on your firmware version. You’re listening and watching for a clean, complete switch rather than anything catching partway.
If you have the Combo, confirm the PTFE tube runs cleanly from the AMS unit to the toolhead without kinks or tight bends, since a pinched tube shows up later as inconsistent extrusion rather than as an obvious error at setup time.
Chamber heat, ventilation, and power
The X2D’s chamber includes active heating, which is what lets it handle ABS, ASA, and other materials that warp badly in an open, unheated setup. Treat it the same way you would any enclosed printer running those filaments: run it in a room with reasonable airflow, and don’t tuck it into a closed cabinet with no ventilation path for the exhaust. If you’re printing ABS or ASA regularly, venting the exhaust outside or running the room’s ventilation during long prints is worth the minor hassle, particularly if the printer lives somewhere you spend a lot of time.
On the electrical side, plug the X2D directly into a wall outlet rated for its power draw rather than daisy-chaining it through a power strip loaded with other equipment. Keep the intake and exhaust vents on the case clear of walls, boxes, or fabric, since blocked airflow undermines both cooling and the chamber heater’s ability to hold temperature.
Your first print
Once calibration finishes and the mechanical checks look clean, print something simple as a baseline before moving to your own models. A calibration cube or a Benchy from Bambu Studio’s built-in model gallery is enough to confirm first-layer adhesion, dimensional accuracy, and that the toolhead is switching nozzles correctly if you’re already running a dual-material file. If anything looks off on that first print, it’s much easier to trace back to a setup step now than after you’ve queued up something complicated.
