OrcaSlicer: Batch Print & Upload For Multi-Plate Projects

In the realm of 3D printing, OrcaSlicer stands out as a powerful tool, particularly for projects involving multiple build plates. While OrcaSlicer efficiently handles slicing multiple plates at once, the process of uploading each plate individually can be time-consuming. This article explores the need for a streamlined batch upload functionality, similar to the existing 'Slice All' option, to enhance user experience and efficiency.

The Problem: Individual Uploads for Multi-Plate Projects

Currently, OrcaSlicer users working on projects with multiple build plates can slice all plates simultaneously using the 'Slice All' feature. However, the subsequent step of uploading each plate to the printer requires individual attention. This manual process can be tedious, especially when dealing with a large number of plates. Imagine slicing ten plates, only to realize you selected the wrong material and have to re-upload each one separately – a scenario where batch upload functionality would be a significant time-saver.

This issue becomes particularly relevant for users who primarily work with a single printer, where the need to switch between plates is frequent. A batch upload option would minimize manual intervention and streamline the workflow, allowing users to focus on other aspects of their 3D printing projects.

Proposed Solution: Introducing the 'Print All' Feature

The ideal solution is to implement a 'Print All' option, mirroring the functionality of the existing 'Slice All' feature. This new feature would allow users to upload all sliced plates to their printer in a single action. To ensure a smooth user experience, the software should intelligently handle situations where only some plates are sliced, uploading only the prepared plates.

Functionality of the 'Print All' Option

When the 'Print All' option is activated, the software should automatically generate file names based on the user's configured format. To simplify the process, file names should not be editable at this stage. Furthermore, to avoid overwhelming the user with complex selections, the 'Upload and Print' button could be disabled. Instead, users would have the option to initiate their preferred plate manually, ensuring complete control over the printing sequence. In this scenario, only 'Upload' and 'Cancel' buttons would be displayed, providing a clear and focused interface.

The 'Print All' feature should not present any issues for exporting G-code, as this process would simply involve multiple individual exports handled automatically by the software.

Enhanced Workflow for Klipper Users

For users of Klipper firmware, an additional enhancement would be the option to automatically add uploaded jobs to the printer's job queue. This functionality, potentially implemented as a checkbox within the 'Print All' dialog, would further streamline the printing process, allowing users to queue multiple prints without manual intervention. While this could be considered a separate feature request, its integration with the 'Print All' functionality would create a seamless and efficient workflow.

Alternatives Considered: The 'Print Selected' Approach

An alternative approach to batch uploading is the implementation of a 'Print Selected' button. This option would provide users with granular control over which plates to upload. To facilitate this selection, a checkbox could be added to the preview tab for each plate, allowing users to easily select the desired plates. The 'Print Selected' feature could also be extended to selective slicing, offering a unified interface for both slicing and uploading specific plates.

Advantages of 'Print Selected'

• Granular Control: Users can choose exactly which plates to upload.
• Flexibility: Suitable for scenarios where only specific plates need to be printed.
• Potential for Selective Slicing: The same interface could be used to slice only selected plates.

Disadvantages of 'Print Selected'

• Increased Complexity: Requires an additional selection step for each print.
• Potential for Errors: Users might forget to select all intended plates.

The Case for 'Print All': Simplicity and Efficiency

While the 'Print Selected' option offers flexibility, the 'Print All' approach prioritizes simplicity and efficiency. By automating the upload process for all sliced plates, the 'Print All' feature minimizes manual intervention and reduces the potential for errors. This streamlined workflow is particularly beneficial for users who routinely print all plates in a project.

Ultimately, the choice between 'Print All' and 'Print Selected' depends on the user's specific needs and preferences. However, the 'Print All' feature offers a compelling solution for users seeking a quick and efficient way to upload multiple plates in OrcaSlicer.

Addressing Existing Queueing Behavior

It's worth noting that OrcaSlicer already exhibits queueing behavior when the 'Print' button is clicked repeatedly in rapid succession. This existing functionality suggests the underlying architecture supports queueing print jobs. Leveraging this existing behavior, the 'Print All' feature could seamlessly integrate with the software's queueing mechanism, ensuring a smooth and reliable printing process.

Conclusion: Enhancing OrcaSlicer with Batch Upload Functionality

The addition of a 'Print All' or 'Upload All' function to OrcaSlicer would significantly enhance the user experience, particularly for projects involving multiple build plates. By streamlining the upload process, this feature would save users time and effort, allowing them to focus on the creative aspects of 3D printing. Whether implemented as a 'Print All' button or a more granular 'Print Selected' option, batch upload functionality is a valuable addition to OrcaSlicer's robust feature set.

The proposed 'Print All' feature aligns perfectly with OrcaSlicer's commitment to providing a user-friendly and efficient 3D printing workflow. By simplifying the process of uploading multiple plates, this feature would empower users to tackle complex projects with greater ease and confidence.

In conclusion, implementing a batch upload function, such as a 'Print All' option, in OrcaSlicer would address a significant pain point for users working with multi-plate projects. This enhancement would streamline the workflow, save time, and ultimately improve the overall 3D printing experience.
