1.4.3 Tool Kit Every Nautilus ships with a tool kit that contains some of the key tools and replacement parts you will need to maintain your Nautilus and post-process your 3D printed parts. This tool kit is designed to get you started, you will probably find that there are additional tools you want to use. -
Page 23: Filter
A filter designed specifically for the Nautilus is in the works, but in the meantime you may want to implement your own solution. Under the black cover on the back of the Nautilus are two 80mm fan ports. -
Page 24: Product Support
The Nautilus utilizes the powerful Duet platform for the mainboard, touch panel, and web control. The Duet is a modular and e xtremely adaptable, open source 3D printer and CNC control system . The Nautilus is not the only printer that uses this system; the Duet community is quite large and a great secondary source of information and support. -
Page 25: Getting Started
2 Getting Started 2.1 Getting Ready to Print Ensure that the Nautilus is plugged in with the supplied power cable. The power plug on the Nautilus is located on the back of the printer at the bottom. Maker sure ALL packaging detailed in the unpacking guide is removed and the printer has been placed on a clear, stable surface in a well-ventilated area before powering on the printer using the red switch located on the left side of the Nautilus. -
Page 26: Connecting To A Network
ⓘ The WiFi module in the Nautilus is not compatible with 5GHz connections. However, if your network has both 5GHz and 2.4GHz bands, a computer on the 5GHz band can print to a Nautilus on 2.4GHz. Adding a Network 1. Power on the Nautilus in range of your WiFi network 2. -
Page 27: Password Protecting Your Nautilus
2.1.4 Password Protecting your Nautilus Anyone on the same WiFi network will be able to access and control your Nautilus if you do not password protect ● With your Nautilus powered on, navigate to the Console tab and click the keyboard icon in the top right. -
Page 28: Loading/Unloading Material
Purge Bucket The purge bucket is an essential part of the Nautilus, and it must be correctly seated in its mounting bracket at the left front corner of the build area. The p urge bucket is used to collect waste material from purging the nozzle which is done at the beginning of every print, resuming a print if a print is paused, and during material load and unload. -
Page 29: Cura Setup
1. Open Ultimaker Cura ⓘ If you have not opened Cura before, you will have to add a printer because the Nautilus will not be listed until the plugin is installed. Any printer will do. 2. Open the Marketplace using the button in the upper right-hand corner... - Page 30 Hydra Research Nautilus Plugin→Nautilus Connections 9. In the window that opens you can give your printer a name and enter your Nautilus’ IP address which is displayed on power up and can be found in the console tab on the Nautilus display.
-
Page 31: Connecting To Your Nautilus
Duet Web Control You can also connect to your printer from any internet connected device on the same network as the Nautilus by typing your Nautilus’ IP address into your browser’s search bar. Your Nautilus’ IP address is displayed on power-up and can be found in the console tab on the Nautilus display or under Networking in the Macros menu. -
Page 32: Printing
Uploading over WiFi Once you have sliced your 3D model, you're ready to upload it to your Nautilus. The primary way to do this is to use the Upload button that replaces the Prepare button once the slicing has finished. If you have multiple Nautili connected you can select the one you wish to upload to by clicking the arrow located on the right side of the upload button. -
Page 33: Starting A Print
3.2 Starting a Print There are two ways to start a print. We recommend always starting a print from the Control tab on the Nautilus as it is always a good idea to visually check that everything is set up properly on your Nautilus before initiating a print. -

Whenever handling the free end of a spool of filament a lways make sure the free end is in your hand or secured in the spool/ printer . All spools supplied by Hydra Research have holes in the rim for securing filament when not in use. -
Page 36: Post-Processing
3.6 Post-Processing After printing, many parts require post-processing to remove printed aids like brims and supports. Parts can also be post-processed to change the aesthetic finish of the part, this is material specific and is covered briefly in section 5. Brim Removal The deburring tool and hobby knife are the two best tools for removing brims from your parts. -
Page 37: Advanced Usage & Techniques
4.1.1 Temperature tuning (PID) The heaters on your Nautilus have been calibrated in the factory for typical usage environments of about 25°C (77°F). However, if you are printing in a very hot or very cold environment you may notice larger than normal fluctuations in the Nautilus’... -
Page 38: Automatic Bed Leveling
Your Z-offset is now set for this tool. The Nautilus will look up this value at the beginning of every print using this Tool Cartridge. You should not have to repeat the process for this Tool Cartridge. That said, you may find you need to adjust it slightly from time to time. -
Page 39: Power Loss Recovery
4.3 Power Loss Recovery Power loss recovery provides the opportunity to r esume a job in the event of a power loss to your Nautilus . This feature is not guaranteed to salvage the job every time, but in many cases you will be able to resume printing. -
Page 40: Materials
PLA is a very hard material which makes parts quite b rittle . When PLA parts break they tend to s hatter . PLA will also b ecome very brittle if left in the PTFE feeder tubes commonly used on 3D printers including the Nautilus. -
Page 41: Co-Polyester - Tough And Chemically Resistant
80 - 110°C depending on the material blend. Co-polyesters also exhibit very low warping and are an excellent choice for l arge parts . The majority of the parts on your Nautilus are printed with Co-polyesters. Co-polyesters can be a lmost as easy to print as PLA but offer s uperior mechanical properties . Co-polyesters tend to be more ... -

Tool Cartridge. Troubleshooting Issues Loading Filament ● Insert filament into your Nautilus until strong resistance is met, it should feel like the filament is running into a wall. ● Run the Material Load macro, if the filament begins to load into the printer, then your extruder is successfully loading filament. - Page 56 B e careful not to lose the springs on the tension screws if they come out with the screws 6. Use the flush cutters included with your Nautilus to cut the filament at the filament insertion point on the top of your Nautilus.

Page 57: Cleaning The Extruder
If you are comfortable working in tight spaces with limited visibility, this process can be done without removing the left side panel of the Nautilus. However, to make things more visible and accessible we recommend removing the left side panel for this procedure. -
Page 58: Extruder Tension
6.3.3 Extruder Tension The extruder tension refers to the amount of tension applied to the dual extruder gears that push filament into the Tool Cartridge. You should not need to adjust your extruder tension often, but if you have performed maintenance on the extruder or the extruder does not seem to be gripping the filament properly, you may need to adjust it. -
Page 59: Tool Cartridges
5. Use the needle included with your Nautilus to poke into the nozzle and clear the jammed material but d o not touch the nozzle or heater block. I t is recommended to wear gloves and/or use pliers to grip the needle. -
Page 60: Replacing Tool Cartridge Ptfe Tubing
Proper belt tension is crucial for accuracy and repeatability of the Nautilus’ motion system. To check the belt tension, pluck a long stretch of each belt in a similar place. It should resonate like a guitar string and both belts should produce a similar sound. -
