==== Parts List and Sources ====
\\ 
The primary resources needed for this tutorial include the OrcaSlicer software and specific printer profiles. The details are outlined in the table below:
\\
^ Resource ^ Description ^ Source ^
| OrcaSlicer Software | Software for 3D printing slicing and management | [[https://github.com/SoftFever/OrcaSlicer/releases/|OrcaSlicer's release page]] |
| Printer Profiles Package | .zip package containing the printer profiles needed for access | Provided by another lab member |
| WiFi and Octoprint Credentials | Username and passwords for the WiFi and Octoprint logins | Provided by another lab member |
\\


----

==== Setup ====

**Step 1: Launch OrcaSlicer**
\\
  * Open the OrcaSlicer software on your computer.
  * OrcaSlicer will ask for the addition of specific printer models as part of the first setup. 
  * The printers that <color #22b14c>MUST be selected (by clicking the checkbox under them) are the CR-10 (V2) and QIDI X-Max (the first version)</color>
  * It would also likely benefit the user to check the boxes for the Generic Marlin and Generic Klipper printers.

{{ sricoy:3dprinters:screenshot_2024-01-16_143841.png?500 |}}
\\
  * Download and import the provided printer profiles ("printer_profiles.zip").
  * Extract the contents of the given .zip file into a folder 
  * Use the 'Import Configs' feature in OrcaSlicer to open in the import dialogue.

\\

{{ sricoy:3dprinters:f85c387769c35c2a90d618ec4939b0fe.png?500 |}}
\\

  * Select all of the configs in the folder you extracted to (CTRL+A works well here) and click "Open" to continue the import process.

\\

**Step 2: Printer Overview**
\\
  * Familiarize yourself with our CR-10 printers. From left to right in the photo: Pacman, Holiday, Zigzag, and Dave.

==== Slicing and Printing ====

**Step 3: Load Your 3D Model**
\\
  * Open your 3D model file and position it on the print bed.
  * Use the OrcaSlicer toolbar for adjustments.

{{ sricoy:3dprinters:f3596e0091687c7e5e3c95c77d5f3f07.png?500 |}}

==== Configure Print Settings ====

**Step 4: Configuring Print Settings**
\\ 
On the left side of the OrcaSlicer interface, you'll find three important settings categories to configure:

  * **Printer Selection (listed as "Printer"):**
    \\ 
  * Choose your printer from the options available, such as a CR-10 (there are 4 of these), X-Max, the Taz, or others in the lab that may not be included at this time.
  * Note that the Taz Workhorse will have its own dedicated section. This general guide will work well for the Creality CR-10 V2 and V3 models, and are currently set to match the correct nozzle size for each.
    \\

  * **Filament Type:**
    \\ 
  * Select the type of filament loaded on your chosen printer. Common options include PLA, PETG, ABS, or ASA, depending on your project's requirements.
  * Avoid adjusting the parameters in these profiles as they've been proven over many cycles. Most adjustments will come from the "Process" profiles.
  * Review which filament is actually loaded on the printer you've selected. Often, one printer will consistently use a type of filament to ensure more reliable performance.
  * Use a glue stick for PETG on glass plates but avoid using PETG on PEI coated sheets due to the risk of damage.
    \\
{{ sricoy:3dprinters:45f325e9691f233e1912be483f64d2ad.png?500 |}}

  * **Printing Profile (listed as "Process"):**
    \\ 
  * Choose the appropriate custom DASL profile for your filament and printer combination. Example: "0.20mm Layers CR10V3 PETG (0.4mm Nozzle) without Supports".
  * These profiles are pre-configured for materials like PLA and PETG at the time of writing. These are given without support structures, which you can enable in the "Support" section of the print settings if needed.
  * The settings should work for most materials when chosen accordingly, and layer heights can be adjusted as needed.
  * <fc #ff0000>It is highly recommended that the user stick to the DASL profiles given as they are made to work consistently. If they do not work, then they must be modified for ease of future printing.</fc>

=== For the beginners: What CAN you change without compromising the profiles?===

\\
  * Sparse infill density and the pattern (this is in the Strength section)
  * Top/Bottom surface and solid infill patterns
  * Top and bottom shell layers
  * Wall loops
  * Brim and brim type
  * Skirt loops
  * Print sequence
  * Layer height (up to 75% of your nozzle width).
\\ 
Feel free to experiment a bit.

===Safety measures:===
\\ 
There are a few safety measures implemented in the profiles. For example, you might get a warning if you increase the layer height too much. Or you might increase the speed, but the program will slow it down to stay inside the printer's limits.
\\ 
\\
It is still very possible to have a print fail, but with the profiles given there is a strong likelihood of success.
\\
**IF YOU DO NOT KNOW WHAT A SETTING MEANS, PLEASE DO NOT CHANGE IT.**



**Step 5: Slice Your Model**
\\
  * Use the 'Slice Plate' or 'Slice All' feature to prepare your model for printing.

**Step 6: Preview Your Print**
\\
  * Check the sliced model in the 'Preview' tab.
  * Ensure the print settings are correct.

**Step 7: Connect to the Printer**
\\
  * Be sure you are connected to the 3D printer wifi router. The ID at this time is "daslprint3d" and if you are authorized you'll be given the password.
\\
{{ sricoy:3dprinters:d497a65d242bebace977fa8aa36b273c.png?500 |}}
\\
  * Log in to the 'Device' tab within Orca, using the provided username and password you received from other lab members.

\\

\\
{{ sricoy:3dprinters:d562a5da24abd1cc6bebb9418510abc2.png?500 |}}

  * Select the correct printer from the list. If using Pacman for example, "/dev/octo_pacman/" is the correct printer.
  * Do not be worried that the "Zigzag" <fc #ff0000>profile</fc> is selected within Octoprint. This has nothing to do with your actual print settings within Orca slicer.
  * Additionally, do not worry if the web cam feed is on the wrong printer, this is still being resolved.


**Step 8: Starting the Print**
\\
  * Click 'Print' and select 'Upload and Print' to start the printing process.

==== Post-Printing Process ====

**Step 9: Removing Printed Objects**
\\
  * Allow the build plate to cool before attempting to remove printed objects, especially for PETG.
  * Use appropriate tools and techniques depending on the build plate type (glass or PEI coated steel).

==== Troubleshooting (to be updated as issues arise) ====
\\
\\
If you have issues connecting to Octoprint, look at your printer and click the connections icon (commonly called the wifi symbol), then click "Browse". 
\\
Your system might ask if you want to allow Orca to access the network. Say "yes" to this, and then it should work.
\\
If network problems persist, please consult the current standing 3D print room manager (at the moment this is Thomas McNulty).
\\
==== Final Words ====
\\ 
This tutorial aimed to provide a comprehensive guide for beginners to start using the DASL 3D printers. By following these instructions, users should be able to confidently print their 3D models and understand the basic principles of FDM printing. Future enhancements to this tutorial could include advanced printing techniques and troubleshooting common printing issues.
