I build tools for 3D printing and fix the problems I run into along the way. Most of my work right now is on the Snapmaker U1: the slicer, the firmware, and getting projects from other printers onto it.

kuzuriao.com

Converts Bambu Studio, Creality Print and Anycubic Slicer Next .3mf projects to Snapmaker U1 / OrcaSlicer, keeping as much of the original print settings as possible.

• Web app: b2o.kuzuriao.com, drag and drop
• CLI: b2o (npx @kuzuri.ao/b2o), MIT licensed, for scripting and batches
• Privacy: only the slicer settings ever leave your machine, never the 3D models. Run --dry-run to see exactly what would be sent.

The U1 could crash the toolhead into finished objects in print-by-object jobs in three places: homing at the end of the print, tool changes, and pausing. I reported it to Snapmaker with videos, then fixed each one where it can be fixed.

All of them were tested on a U1 with the same collision test file, which is attached to the PRs.

The clearance check depended on the order objects were listed in, and flagged material below the gantry rod as a collision.
