2BAS6-BQDRYMINIFilament Dryer

BQDry Mini User Manual Product Overview: BQDry Mini is a compact heating module designed for 3D-printing environments. It provides stable active heating for enclosures that do not have built-in heating. Its modular design allows installation inside devices such as the Bambu Lab AMS without modifying the original structure or compromising the seal. This adds active filament-drying capability for filament storage, maintaining a warm environment during printing, and supporting high-temperature material printing. Multiple BQDry Mini units can also be combined to expand the heating area for different enclosure sizes. Temperature, duration, and other settings can be precisely controlled through the Web UI. Key Features: 1. No-Modification AMS Installation: Designed specifically for the first-generation Bambu Lab AMS. Installs easily inside the AMS without permanent modification, adding active heating capability. 2. Precise Temperature Control: Adjustable from 35°C to 60°C to meet the drying and print-environment requirements of different filament types. 3. Versatile Applications: Suitable not only for the AMS, but also for printer chambers, filament storage boxes, and other enclosed heating applications. 4. Convenient Dual Control: Control the temperature, duration, and operating status using either the physical buttons or the Web UI. 5. Efficient, Safe Heating: Low-voltage power and multiple safety protections provide reliable heating for stable long-term operation. Applications: Application 1: AMS Filament Drying For users of the first-generation Bambu Lab AMS. BQDry Mini raises the temperature inside the AMS to actively dry filament. Its independent power supply allows filament to be dried while printing. Application 2: Add Chamber Heating For 3D printers without an actively heated chamber. Adding BQDry Mini provides environmental heating and expands the range of materials the printer can use. Application 3: Improve Filament Storage Install BQDry Mini in another sealed filament box or storage enclosure to reduce moisture exposure and extend filament storage life. Specifications Product: Filament Dryer Model No.: BQDry Mini Input: 24 V DC, 5 A Rated power: 116 W Operating environment: Ambient temperature: 10-35°C; Relative humidity: <95% Heating range: 35-60°C (at a standard ambient temperature of 26°C) Timer: 0-99 h (plus Continuous mode) Product dimensions: / Package Contents Image Item Qty. Control module 1 Output module 2 24 V 5 A DC power adapter 1 DC connector adapter cable Control module power cable 1 AMS replacement power board 1 Y-cable 1 AMS replacement handle 1 Thin white nylon washers 4 Cable clips 2 Mounting tape 3 1.5 mm L-shaped hex key 1 Installation 1. Prepare the AMS: Disconnect the cable and PTFE tube between the AMS and the printer. Remove all filament from the AMS and store it temporarily in a dry location. 2. Remove the Rear PTFE Tube: Open the AMS lid. Press and hold the internal PTFE tube release collar, then pull the PTFE tube out from the rear of the AMS. 3. Remove the Frame Screws: Use the included hex key to remove the two screws from the AMS main frame, as shown. 4. Lift the Main Frame: Press the release button on the five-way hub, then fully lift the rear of the main frame. Note: Internal cables are still connected. Do not pull or lift forcefully. Disconnect the 485 communication cable and power cable from the AMS power board. Remove the AMS main-frame assembly and set it aside. 5. Replace the Power Board: Remove the original AMS power board and install the [AMS Replacement Power Board]. When securing the replacement board, place a nylon washer on the nut side of each screw to prevent overtightening from damaging the board. Return the original AMS board to its antistatic bag and store it safely. 6. Reconnect the Cables: Reconnect the 485 communication cable and power cable to the new board. Take the [Control Module Power Cable] from the accessory pack and connect either end to the new power board. 7. Route the Power Cable: Install the two cable clips under the AMS main frame as shown. Secure the [Control Module Power Cable], then route it from the center of the AMS toward the front, following the illustrated cable path. Keep the cable clear of the AMS gear assemblies and all moving parts. 8. Apply Mounting Tape: Apply the double-sided [Mounting Tape] to both [Output Modules] and the [Control Module] as shown. The tape will secure the modules during installation. 9. Connect the Modules: Connect the [Control Module Power Cable] to the [Control Module]. Connect the two [Output Modules] to any two of the three identical ports on the control module using their attached cables. 10. Mount the Modules: Peel off the release liners from the mounting tape, then attach the control module and output modules to the positions shown on the AMS main frame. Note: The rear cover of the control module has a cable-routing channel for the power cable. Press part of the cable into the channel so the module sits flush. 11. Reinstall the Main Frame: Place the AMS main-frame assembly, with the control and output modules installed, back into the AMS housing as shown. 12. Secure the Main Frame: Reinstall the two screws and the PTFE tube removed earlier. 13. Connect the External Cables: Connect the [Y-Cable] and [DC Connector Adapter Cable]. The Y-cable preserves support for daisy-chaining multiple AMS units. You may omit it when no AMS daisy chain is required. The DC connector adapter cable connects the DC power adapter to provide independent power to the BQDry Mini. 14. Install the Replacement Handle: Use the included L-shaped hex key to remove the original AMS handle and install the replacement handle. The replacement handle offers two opening positions. Adjust the gap as needed to create a suitable moisture exhaust path, allowing humid air to escape and helping prevent condensation inside the AMS. Installation is now complete. Connect power to begin using the BQDry Mini. Operation 1. On…
