OrcaSlicer for Hermes

Prepare, slice, preflight and export 3D prints with stock OrcaSlicer profiles. Includes explicit printer upload/control, camera snapshots and monitoring through supported protocols. Protocol and hardware limits are documented. Independent of OrcaSlicer and Nous Research.

Good to know before installing

Executes the installed local slicer and exposes printer upload, start, pause, resume and cancel; agent-supplied confirmation is not independent human authentication. Printer/camera credentials are read from ORCA_*/HERMES_ORCA_* environment variables named in tool arguments (HTTPS required unless allow_plaintext_credentials is set); plugin state lives in ~/.hermes-orca (HERMES_ORCA_HOME), outside HERMES_HOME.

From the plugin's catalog listing.

How to install

Install it. Hermes asks for any API keys it needs, then asks whether to turn it on.
hermes plugins install orcaslicer
Said no? Turn it on later:
hermes plugins enable orcaslicer
Restart Hermes so it loads the plugin.

Some plugins also need a sign-in or settings: see Full setup & settings. Memory plugins ask whether to become your memory provider instead. Steps follow the official plugins guide (opens in a new tab).
