OrcaSlicer 2.4.2: profiles load again and fewer crashes

The OrcaSlicer project released version 2.4.2 on 7 July 2026. It brings no headline features, and that is precisely why it is worth installing: it is a maintenance release that fixes things which were breaking everyday work.

What does this version fix?#

According to the official release notes, the changes fall into four blocks.

Profiles that load again. Presets built on a printer or a filament that was later renamed or deleted now load correctly. In practice this reduces the "missing profile" warnings that appeared when updating from earlier versions, an annoying problem for anyone with profiles tuned per material.

Cloud synchronisation. Filament settings you had disabled no longer switch themselves back on after syncing, and synchronisation messages now state exactly which profile is involved. On top of that, having two copies of OrcaSlicer open under the same account no longer causes random sign-outs.

Bambu Lab network plugin. Installing and updating that plugin is reliable again, including when switching versions on Windows, where reinstallation prompts kept repeating.

Crashes fixed. Three reproducible freezes are gone: rotating the purge tower, using the measurement tool and running the pressure advance calibration. Slicing issues, print time estimation problems and the reload-from-disk function for STEP models after reopening a project were also fixed.

What is new in this release?#

The release adds a file name marker for the first object on the plate, wiki links in the preferences dialog and filament profiles from one additional manufacturer.

Is it worth updating?#

If you use OrcaSlicer as your main slicer — and in the Spanish-speaking world that is increasingly common, especially among Creality and Elegoo owners — this is the kind of update you install without thinking too hard about it.

Two practical recommendations before updating:

1. Export your filament profiles. Even though this version improves profile recovery specifically, keeping a copy of the flow and temperature values you calibrated saves you afternoons of work if something goes wrong.
2. Always download from the official repository. There are sites that redistribute slicer installers with extras bundled in. Official builds are published in the project's release listing, linked in the sources for this piece.

Context#

OrcaSlicer is a free slicer derived from the PrusaSlicer and Bambu Studio tree, and it has become the common ground between ecosystems: it lets you work with machines from different brands using a single tool, and it ships with built-in calibration routines for flow, temperature, pressure advance and retraction that previously had to be set up by hand. That set of calibrations is today its strongest argument against each manufacturer's own slicer.
