¶ H2D
The following section covers the 3D printing part of the H2D 3D Printer.
If you have a H2DL printer, you can learn more about the H2D Laser Module by clicking here or about the H2D Cutting Module by clicking here.
¶ Homepage
On the left side of the homepage is an on-screen menu bar that includes Homepage, Controls, Filaments, Settings, and HMS; on the right side is the Print Files, Nozzle Temperature, Filament, Network Settings, and HMS.
¶ Controls
¶ 1. Air Condition
Depending on the filaments, you can choose the appropriate air condition system.
- Cooling mode: Cooling mode is suitable for printing filaments with low heat resistance, such as PLA/TPU; the chamber heat circulation fan remains off in this mode.
- Heating mode: Heating mode is suitable for printing ABS/ASA/PC/PA and other filaments with high heat resistance. When the chamber is heated, the system will automatically switch to the heating mode; in this mode, the chamber heat circulation fan will automatically turn on, and the auxiliary part cooling fan will remain off.
- Part Cooling fan: It is installed on the toolhead, and is used to ensure adequate cooling of the printed layers during the printing process. It helps in rapidly cooling the material as it is extruded, allowing each layer to solidify and maintain its shape before the next layer is deposited.
- Auxiliary Part Cooling Fan: It is installed on the left side of the chamber, and provides a better cooling condition for high-speed printing.
- Chamber Exhaust Fan: When the chamber cools down, the air condition will switch to cooling mode. The speed of the chamber exhaust fan will increase as the chamber temperature rises during printing. When the chamber temperature is lower, the chamber exhaust fan will reduce its speed to 30%.
- Chamber Heat Circulation Fan: During chamber heating, the printer will switch to heating mode. After setting the chamber temperature, the chamber heater (composed of PTC and the chamber heat circulation fan) will begin to operate, with the PTC heating at full power and the fan running at full speed. Once the chamber temperature reaches the target value, the fan speed remains constant while the PTC power decreases to maintain a stable temperature.
- Chamber Temperature: Set the appropriate chamber temperature according to the different filaments. Low chamber temperature is suitable for printing filaments such as PLA and PETG; high chamber temperature is suitable for printing warp-prone filaments such as ABS.
¶ 2. Speed
Set the printing speed mode.
-
Ludicrous: 166% of normal print speed and acceleration
-
Sport: 124% of normal print speed and acceleration
-
Standard: normal print speed and acceleration

NOTE: You can also turn on the drying function in Setting > Toolbox > Dry Filament.
If multiple AMS 2 Pro/HT are connected, you can click the icon in the upper left corner to switch between different devices, view the real-time humidity and temperature data of each AMS, or start drying.
¶ 4. External spool
Click the external spool icon to edit, load and unload filaments;
¶ 5. Tools
- Auto Refill: When the brand, type, and color of the filaments are identical, the system will establish an automatic refill relationship. When the current filaments run out, the printer will automatically switch to another filament with the same properties to continue printing.
Note: An automatic refill relationship can only be established if both identical filaments come from the same extruder connected to the AMS, meaning left to left and right to right. If the filaments come from different extruders, an automatic refill relationship cannot be established.
- AMS Setup: When the AMS 2 Pro is connected to the H2D printer for the first time, it requires setup to detect which side of the extruder the AMS is connected to.
- Auto AMS Setup: AMS sends the filament to the extruder. Each left and right extruder is equipped with a Hall sensor. The signal triggered by the Hall sensor is used to determine which extruder AMS is paired with.
Note:
Ensure that the filament is inserted into AMS 2 Pro (any slot is fine).
Any loaded filament must be unloaded in advance.
Ensure that no filament is broken in the buffer. Ensure that there is no residual filament inside the filament buffer (to avoid leftover filament inside).
- Manual AMS Setup: Manually adjust the pairing relationship between AMS and extruder when there is no filament in AMS. When an AMS has sent the filament to the extruder, its icon will be gray (AMS-B in the figure below) and the pairing relationship with the extruder cannot be changed.

¶ 5. Calibration
- Print Calibration: Includes motor noise cancellation, vibration compensation, auto bed leveling, high-temperature bed leveling and nozzle offset calibration.
-
Motor Noise Cancellation: Reduces the noise generated by the motor during printing, especially when printing for a long time or at high speed. By optimizing the motor's operating algorithm and control strategy, it can not only reduce noise, but also make the print surface smoother, thereby improving the final printing effect.
-
Vibration Compensation: When any vibration is detected in real-time during printing, the toolhead position can be automatically adjusted to ensure the accuracy of printing. Especially when printing complex or detailed models, this calibration can effectively prevent errors caused by vibration and ensure that each layer is completed accurately.
-
Auto Bed Leveling: Through intelligent algorithms, the distance between the nozzle and the build plate is adjusted to ensure that the gap in each corner is consistent, which can effectively avoid printing defects caused by uneven heatbed, thereby improving printing accuracy.
-
High-temperature Bed Leveling: Before printing with high-temperature filaments such as ABS/ASA/PC/PA, high-temperature heatbed calibration can ensure that the heatbed remains stable in a high-temperature environment, effectively preventing warping or poor adhesion of the first layer, and improving the quality of the first layer print.
-
Nozzle Offset Calibration: If the positioning of the two nozzles is offset, it may cause the model to be misaligned or layer-shifted during printing. If you find that the model has an obvious layer shift after switching nozzles during printing, it is recommended to perform a nozzle offset calibration. This process uses the eddy current sensor in the toolhead and the nozzle offset calibration sensor behind the heatbed to ensure the accuracy of the nozzle position to improve the quality and accuracy of the print. Through effective calibration, you can reduce printing errors and ensure perfect alignment of each layer.
- High-Precision Nozzle Offset Calibration: Load two filaments, one dark and one light, to two nozzles respectively, and use AI visual inspection technology to accurately calibrate the offset of the two nozzles in the XY direction to improve print quality and accuracy.
- Live View Camera Calibration: By identifying specific marks on the heatbed and calibrating the position and angle of the live camera, the detection error caused by camera viewing angle deviation and position error can be reduced, thereby significantly improving its detection accuracy and achieving higher image capture quality.
- Motion Accuracy Calibration: Designed for users who have high requirements for print quality, it aims to solve the absolute positioning problem in the 3D printing process, thereby improving printing accuracy, especially for large-size printing. Through this process, motion hysteresis and motion distortion can be significantly suppressed, ensuring a more accurate printing.
For more information on motion accuracy calibration, please refer to: Motion Accuracy Calibration.
¶ 6. Toolbox
- Dry Filament: Select the filament type, set the drying temperature and duration, and dry the filament.
- Laser Module Cleaning: Regular cleaning of the laser module prevents the accumulation of powder and debris, ensuring the normal operation of the equipment and extending its service life. The printer will assess the degree of contamination of the printer based on the total engineering time and laser task type in Bambu Suite. The length of the green progress bar on the left side of the screen will decrease as the laser module is cleaned; if the progress bar turns red and displays "Cleaning Required Immediately", cleaning is required. Specific tutorials can be obtained through the QR code on the right. Please refer to: Regular maintenance recommendations for 10w laser module.
- Nozzle Cold Pull Maintenance: When the extruder motor frequently overloads and reports errors at normal printing flow, it means that the nozzle resistance is too large and needs to be cleaned urgently; at the same time, since TPU is extremely sensitive to nozzle resistance, if the nozzle has been used to print other filaments before, it is recommended to perform cold pull cleaning on the nozzle before printing TPU to ensure smooth printing. For details on nozzle cold pull maintenance, please refer to: H2D Nozzle Cold Pull Maintenance and Cleaning.
¶ 7. Settings

- Print Options:
 |
 |
-
AI Print Monitoring: Detect spaghetti, purge chute pile-up and nozzle clumping during the printing process, and select the sensitivity to pause printing. The pause sensitivity is divided into high (pause immediately when small problems are found), medium (pause when a certain degree of problem occurs), and low (pause only when there is an obvious abnormality) to adapt to different print quality needs.
-
Build Plate Detection: Detect print plate markings. If the markings are not within the predefined range or do not match the slice file, the printer stops printing. This prevents unplaced or misplaced print plates.
For more information about intelligent detection, please refer to: Introduction to H2D Intelligent Detection.
-
Auto-Recovery from Step Loss: When the motor detects a position shift (lost step), the X-axis, Y-axis, and Z-axis are repositioned and returned to the pre-shift position to continue executing the unfinished G-code to ensure print quality.
-
Open Door Detection: When turned on, the printer will detect whether the front glass door is open, and you can choose to trigger a notification or pause printing when the door is opened.
-
Store Sent Files on External Storage: If printing is initiated through the cloud, the print files will be cached in external storage.
-
Motion Accuracy Enhancement: Designed for users who have high requirements for print quality, it aims to solve the absolute positioning problem in the 3D printing process, thereby improving printing accuracy, especially for large-size printing. Through this process, motion hysteresis and motion distortion can be significantly suppressed, ensuring a more accurate printing.

-
Read Filament on Insertion: After inserting the filaments for pre-loading, AMS will perform RFID reading operation.
-
Read Filament on Startup: Every time you restart the printer, AMS will automatically read the inserted filaments information (the reading process will rotate the filaments).
-
Remaining Filament Estimation: Estimate the remaining filaments when reading the RFID. When this function is turned on, the RFID will be read twice to obtain the filament information and estimate the remaining quantity. After reading the RFID and remaining quantity information of the filament, you can view the filament name above each slot. The small horizontal bar below the filament name shows the estimated remaining filaments.
-
AMS Auto-Refill: When the filaments in one slot of the AMS run out, it can automatically switch to filaments with the same properties in other slots. These properties include brand, type, color, and nozzle temperature. Please make sure to configure the information of all filaments before printing to meet the requirements of auto-refill.
-
Arrange AMS Order: Each AMS is assigned a sequence and displayed on the screen. The purpose of assigning AMSID is to facilitate the identification of their connections. The logic of assigning IDs is: the one directly connected to the printer is AMS-A, the one connected to AMS-B is AMS-C, and so on. If you need to reorder the AMS, you can click "Arrange", which will reset the order information of the AMS. After the reset is completed, please connect the AMS in sequence as needed.
