Print Jobs & Queue

LayerNexus provides print job tracking and a priority-based queue system for managing prints across multiple printers.

Creating Print Jobs

Print jobs are created from parts that have been sliced (G-code available).

  1. Open a part detail page.
  2. Click Create Print Job (or Slice first if no G-code exists).
  3. Select the target printer.
  4. Review the job details (estimated print time, filament usage).
  5. Click Create.

Each print job progresses through the following statuses:

Status Description
Pending Job created, waiting to be queued or started
Queued Job is in the print queue, waiting for a printer
Printing Job is currently printing on a printer
Completed Print finished successfully
Failed Print failed or was cancelled

The print queue provides priority-based management across multiple printers.

Adding Jobs to the Queue

  1. Go to Print Queue in the navigation bar.
  2. Click Add to Queue.
  3. Select the print job and target printer.
  4. Set the priority level.
  5. Click Add.

Queue Priority

Jobs in the queue are ordered by priority. Higher-priority jobs are printed first when a printer becomes available.

Managing the Queue

Action Required Role
View queue Any authenticated user
Add to queue Admin, Operator, Designer
Remove from queue Admin, Operator, Designer

Note

Both Operators and Designers can manage the print queue. Only Operators and Admins can actually start prints on printers (upload G-code and trigger printing).

Uploading G-code to Printers

Once a job is ready:

  1. Open the print job detail page.
  2. Click Upload to Printer.
  3. The G-code file is sent to the printer via the Moonraker API.
  4. Click Start Print to begin.

Printer Connectivity

The printer must be online and reachable via its Moonraker URL. Check the printer profile settings if uploads fail. See Klipper / Moonraker for troubleshooting.

Cost Calculation

Each print job tracks costs based on the printer's cost profile:

Cost Component Description
Filament Material cost based on weight used and spool pricing
Electricity Energy cost based on print time and power consumption
Depreciation Printer depreciation based on print time
Maintenance Maintenance cost based on print time

Viewing Costs

  • Per job: View the cost breakdown on the print job detail page.
  • Per project: View aggregated costs on the project detail page, including all sub-projects.

Workflow Summary

STL Upload → Slice (OrcaSlicer API) → G-code → Add to Queue → Upload to Printer → Print → Complete
  1. Upload STL file to a part
  2. Slice using OrcaSlicer profiles
  3. Create a print job
  4. Queue the job with priority
  5. Upload G-code to the printer via Moonraker
  6. Start the print
  7. Track status until completion
