Status: It's complicated. Offset calibration is not repeatable and needs firmware changes. Progress is being made.

Wifi Network: Nautilus

Password: pilotspace

Web interface: http://1.2.3.4/ or http://gstatic.com/

Software: OrcaSlicer & PrusaSlicer + plugin

About this machine

"The Nautilus is a desktop 3D printer made by Hydra Research. It uses Fused Filament Fabrication technology and has a custom spring steel print surface that magnetically attaches to the build plate. The Nautilus can produce precise and repeatable manufacturing with engineering materials. It also has quick change tool cartridges that allow for high resolution or rapid drafting." - Adapted from Google SGE

Software & Slicing

TLDR:

Download the profile here: https://www.hydraresearch3d.com/slicing

Extract profile zip folder, open Prusaslicer, and drag the "Nautilus" profile into the open window. You can also import it by opening the configuration folder (on mac help -> open configuration folder) and placing the file there.

On the right, click Printers and select the Nautilus. Click Add/remove printers and add a networked printer - make sure to enter 1.2.3.4 for the IP address and Duet for the Host Type.

Printing/Slicing

Please make sure to set up the PrusaSlicer profile as shown above.

• Connect to the Nautilus Wifi Network

• After you slice your model in Prusaslicer, a button will appear to the right of the "slice" button. That uploads the gcode to the machine - click it

• In the popup window, click "upload and print"

• Make sure to confirm the print on the printer

Wifi Setup

The Nautilus will *connect* to UPioT, but the upload process is prohibitively slow. 20+ minutes for a simple model slow. Instead, we'll set up the Nautilus as its own access point. This means that it hosts its own wifi network while printing.

To set up wifi, you'll need to use the Console tab on the bottom of the screen on the Nautilus.

• Press the Keyboard button in the upper left.

• Type M552 S0 and press the "return" key ↩️ to send the command

• The SSID (network name) we'll use is "Nautilus" the password is "pilotspace" and the IP address is "1.2.3.4"

• Still in the console, type M589 S"Nautilus" P"pilotspace" I1.2.3.4 then hit return (↩️) again.

• Type M552 S2 into the console and hit return (↩️) again.

Now the Nautilus will start broadcasting its own wifi network. However, when the printer restarts, these changes will be reverted. To make the changes permanent, we have to access the Web UI.

Find "Nautilus" in your computer's wifi menu, and connect to it using the password we just set. Open a web browser, and go to http://1.2.3.4/ or http://gstatic.com/. Please note that https:// will NOT work.

On the left side, click "File Managment" then "system" and open config.g

The Network section of the config, originally, will look like this:

; NETWORK
M550 PHydra Research Nautilus                           ; Set machine name
M552 S1                                                 ; Enable network
M586 P0 S1                                              ; Enable HTTP
M586 P1 S0                                              ; Disable FTP
M586 P2 S0                                              ; Disable Telnet

Change it to this:

; NETWORK
M550 PHydra Research Nautilus                           ; Set machine name
; M552 S1                                                 ; Enable network
 
; Hotspot mode per modified https://hydraresearch3d.dozuki.com/Wiki/2-Getting_Started
; M552 S0 ; Disable WiFi module
G4 S5 ; Give time for WiFi module to change status
M552 S2 ; Enable AP mode
 
M586 P0 S1                                              ; Enable HTTP
M586 P1 S0                                              ; Disable FTP
M586 P2 S0                                              ; Disable Telnet

Putting ; in front of a line comments it out (disables it). What we've done here is disable the original wifi mode -M552 S1 connects the printer to a network, we want to use M552 S2 instead which makes it host a network.

Note: The guide recommends changing config-override.g instead of config.g, but that file is marked as auto-generated and says not to modify. It's likely that either method will work equally well.

Cura?

Hydra Research recommends using PrusaSlicer over Cura, and does end up being a smoother experience.

The newest version of cura fails to install their plugin properly, so attempt at your own risk.

The Nautilus used to use Ultimaker Cura with a custom plugin that contains relevant print settings, tuning, etc.

Please follow the guide here to get the plugin installed:Installing Plugins
