Orca Slicer Not Working?

Orca Slicer is an innovative software with intuitive features for 3D printing. However, like other slicing applications, it may malfunction for several reasons. Non-planar slicing and spiral mode errors are common reasons behind the application not working. We have discussed them in detail and provided a guide for finding solutions.

Orca Slicer Not Connecting To Printer

Problem

If your network has Fluidd, Orca Slicer displays a 404-error message. It happens during file delivery to the printer.

Fix

Ensure the correct IP address of your software and choose the right API.
Both the printer and your PC must be on the same network without a firewall.
Check if you have configured Fluidd to manage uploads from slicers. Then, restart your network connection and application.
Manual uploading of the sliced files is the last resort for solving the problem.

Orca Slicer Is Not Opening

Problem

You might have downloaded and installed Orca Slicer. But, a pop-up appears when opening the application. What will you do if the software does not start?

Fix

Restart your PC if Orca Slicer does not work, as this step solves most problems.
Check for the latest available update or uninstall the latest version. Again, install the software from our Orca Slicer 3D printing software download page.
You have to use the updated graphics drivers for your device. Outdated ones do not work with your app.
Deactivate the antivirus for a certain time and see if it prevents Orca Slicer from working.
If you still find issues, check the application logs to find error messages.

Alternatives- Modify JSON Configuration for Spiral Mode

There are some other solutions if the above tips do not provide the desired result. Adjust the JSON configuration file for our software.

Access the Configuration Folder- The path is- AppData/Roaming/ user/[numbers]/process
Adjust your JSON File- Run the.JSON file associated with your profile.
Manage Spiral Mode Setting: The spiral mode’s value must not be higher than 1.

To solve these issues, right-click on the Orca Slicer icon and respond to the options for the permissions. You may also select the option Run as Administrator for permissions. Now, again try to use Orca Slicer to see if there are any further issues.

Spiral Mode Error- Partial Slicing

Problems

Many Orca Slicer users face an issue, as the application slices a part of the file. In some cases, only the spiral mode works well. Check how to solve the issues and manage your 3D printing projects.

Fix

Try to find the OrcaSlicer named folders in the User/AppData. Remove the folders to adjust the old settings. Open Orca Slicer to know if the solution has worked.

Orca Slicer Complexity Crash

Problem

Orca Slicer crashes when you deal with complex models.

Fix

Use Nvidia Game Ready drivers to avoid potential crashes.
Close other programs to free up your device’s RAM.
Streamline the model by minimizing triangle count.
Slice the model on a different PC to identify system-oriented problems.
If the slicer is set to high priority, it causes additional issues.
Check the CPU and memory usage in your Task Manager.

These steps will stabilize your slicer and ensure better performance.

Orca Slicer Not Saving Settings

Problem

Orca Slicer is unable to save your settings and shows the default ones when you open it. As a temporary solution, hit the undo arrows and restore the desired settings. There are other tips for a permanent solution to the issue.

Fix

Save the profile after adjusting it- Hit the Save option in the menu.
Your software should be in the latest beta version because developers have solved several issues in it.
Delete or check configuration files to restore the damaged settings.
Access the File tab and click Preferences in the software interface. Turn on the Auto-sync user presets option.
You may also report the problem to Orca Slicer’s community forums.

Orca Slicer Not Showing All Filaments

Problem

In many cases, Orca Slicer does not show filament files. Check the troubleshooting guide for this issue.

Fix

Open the filament JSON files in Filaments.
After running the JSON files, look for filament_id entries. If the null option is chosen, filaments will not be shown.
For the null filament_id, enter a new ID.
Save everything and restart your software to see the appearance of filaments in the AMS.
For the filament profiles important from other applications, they must comply with your printers.
Use scripts to modify filament profiles for compatibility.
In case of corrupted custom filament profiles, recreate them.
Our software has no built-in option to remove corrupted profiles. So, you must be careful during the clean-up process.
Check the visibility of user-defined filaments in your AMS selection.

Orca Slicer Not Working On Mac

Problem

MacOS users experiencing issues with the Orca Slicer usage should check a few important steps for the solution.

Fix

Look for the OrcaSlicer folder and rename it. You can choose OrcaSlicer2 as the new name.
Launch the application and open the setup window to manage your preferences.
In case the Library folder is not visible, modify Finder settings to locate hidden files.
Use the software’s latest Beta version that maintains stability.
Install Homebrew to manage software on the Mac PC.

Orca Slicer Not Setting Filament Temperatures

Issue

Your printer may not produce the desired prints if you have set the wrong temperatures.

Fix

Access the Filament section and choose the type of filament.
Hit the notepad icon and find a pop-up related to filament settings.
In the new window, scroll the page down to the Nozzle Temperature and Bed Temperature fields.
Type the temperatures and ensure the slicer is updated. The older versions have bugs that cause issues.
Restart the application and check if the advanced version works.
The filament settings should correspond to the G-code settings.

Orca Slicer Not Retracting

Problem

Stringing is a common issue in the printing process. It happens due to the nozzle movement and affects the final print.

Fix

Adjust the Z Hop Type and choose Spiral to lift the nozzle during travel moves.
Disable the option Avoid Retraction in Infill. The slicer will have a more effective refraction that reduces stringing.
Turn off the option Wipe Before Retract. It allows the slicer to retract the filament.
Check if there is weak refraction in the slicer output. Increase the speed and retraction distance depending on your filament.
Run a few prints for tests to find any improvement in stringing.

Non-Manifold Edges In Orca Slicer

Problem

If your model has non-manifold edges, check for warnings. Understand the ways to manage problems with edges.

Fix

If you find a popup with a Repair option, click it. Our software will fix the basic issues.
Use Meshmixer or other tools to fix the issue thoroughly.
Our software has analysis tools to locate non-manifold edges.

Non-Planar Slicing In Orca Slicer

Problem

When using non-planar slicing, you may find printing issues and unexpected layer heights. There are some ways to solve this slicing problem.

Fix

Download and install Orca Slicer’s latest beta version.
Verify the settings and activate non-planar slicing; manage the layer height based on your needs.
Check your 3D model to determine its manifold using mesh repair systems.
Use simpler models to analyze non-planar slicing and find any issues.
Experiment with various filaments because every material works differently with non-planar slicing.

Conclusion

The troubleshooting tips for your Orca Slicer software will help you solve basic problems. We have discussed common problems encountered by users. For every issue, we have suggested steps for the ultimate solution. The guide will help you manage your current issues for successful prints.
