+
+Lazarus helps recover failed 3D prints when the partial print is still attached to the bed.
+
+The plugin generates the resume G-code locally inside OctoPrint from the original G-code file, the measured print height, and the detected layer structure of that file. The original G-code is not uploaded to the Lazarus service for processing.
+
+Lazarus includes a guided recovery workflow:
+
+- select the original G-code from OctoPrint storage or your local device;
+- enter the measured height of the saved print;
+- generate a new resume file and a calculated alignment point;
+- establish a safe starting coordinate state;
+- align the nozzle to the saved print using OctoPrint motion controls;
+- download or execute the generated resume sequence.
+
+Printer movement remains user-controlled. Lazarus does not automatically home Z into an existing print.
+
+Optional Moonraker/Klipper support is included through a user-provided local Moonraker address.
+
+Lazarus uses `https://app.lazarus3dprint.com` for activation and subscription validation. If that service is unavailable, Lazarus fails closed for resume generation and execution without causing OctoPrint itself to malfunction.
+
+Lazarus is commercial software and requires an active subscription for resume generation and execution. Pricing, activation, terms, license information, and privacy information are available here:
