What's Changed

  • Orca Slicer now support multi-tool printer by @SoftFever in github.com/SoftFever/OrcaSlicer/pull/6087 ↗ — As requested by many, Orca Slicer now supports multi-tool printers! — Users can define multi-tool(tool changer or IDEX) printers in Orca Slicer. — Features supported:
  1. Assign extruders based on features. — Screenshot 2024-09-14 at 11 47 55 AM.
  2. Ooze prevention, both Idle temperature and Temperature variation approach are supported
  3. Preheat next tool automatically based on time estimation. Support all firmwares(Prusa/Klipper/Marlin/etc)
  4. Supports mixing different line widths in a single print with multiple tools. This allows our printer to print with not only different materials/colors, but also control the line width for specific parts, to improve quality, strength, and speed using different nozzles with varying diameters. — For example, we can use one 0.4mm nozzle and one 0.8mm nozzle in one print; the line width will automatically adjust based on a percentage of the nozzle diameter (you will need to define the line width with a percentage in the settings).

Note Two new tool changer printer profiles have been added into Orca: Generic ToolChanger based on Klipper and Prusa XL 5T. Multi tool printer need to setup the Custom g-codes properly, please ref to these two profiles if you want to define your own.

:heart: Multi tool printer support feature is based on Prusa Slicer's multi tool printer support. Thanks to Prusa team for their open-source work and sharing it with the community!

This new mode introduces a single-pass flow calibration that should cover 95% of cases, provided the printer's extruder has its e-steps/rotation-distance calibrated. Unlike the previous flow rate calibration, this new YOLO (You Only Look Once) calibration only requires print the test once. Please pay attention that mode employs a linear method to adjust the flow rate. For a -0.03 block, the adjusted flow rate is calculated as filamentflowrate - 0.03. Two versions of the YOLO benchmark are provided: a default (recommended) and a perfectionist version.

The default YOLO benchmark features a calibration range of [-0.05, +0.05] with an adjustment step size of 0.01. In contrast, the perfectionist version offers a smaller adjustment range of [-0.04, 0.035] with an even smaller step size of 0.005.

Detailed tutorial will be updated soon in WIKI

We're excited to introduce another fantastic feature, implemented by @igiannakas, specifically designed for perfectionist users! The "Adaptive Pressure Advance" enhancement in OrcaSlicer now offers an automatic adjustment feature for pressure advance settings based on real-time flow rate and print acceleration. This innovative feature helps improve print quality by compensating for varying extrusion dynamics during different speeds. As a result, it enables smoother transitions and more consistent layer deposition.

The adaptive pressure advance also enhances prints by adjusting the pressure in the nozzle more dynamically, reducing artifacts such as blobs or gaps.
