Formlabs prep

Skill mkebiclioglu/formlabs-claude-skills/.claude/skills/formlabs-prep

Prepare a Formlabs print scene from one or more STL/OBJ files and save it as a .form file, without sending to a printer. Use when the user wants to set up a print job for review or later printing, but doesn't want it sent to a printer yet. Lower-stakes companion to formlabs-print.From its SKILL.md

Formlabs print prep (save only)

A non-destructive version of the formlabs-print workflow: same preparation pipeline, but always saves a .form file at the end instead of sending to a printer. Use this when the user wants to inspect the job in PreForm first, or batch-prepare jobs to print later.

Precondition (always)

First action: call health_check. If it errors, the formlabs MCP server is not installed or PreFormServer failed to start. Surface the error, link the user to https://github.com/mkebiclioglu/formlabs-local-mcp, and STOP.

Required inputs

Model file(s) — absolute paths.
Printer + material — same as formlabs-print. If the user names a printer but no material, call list_printer_types to confirm the code, then list_materials and surface the available materials for that printer so they can pick.
Output .form path — absolute path. If they don't specify, default to the model's directory with the same basename and .form extension, and confirm.

Workflow

health_check (precondition).
create_scene.
import_model for each input file. The server defaults repair_behavior=REPAIR and units=MILLIMETERS — leave them unless the user explicitly says otherwise.
auto_orient.
auto_support.
auto_layout (SLA, machine_type starts with FORM-) or auto_pack (SLS, starts with FS).
get_print_validation — surface errors/warnings.
Auto drain holes (SLA only): call auto_add_drain_holes to place drain holes for any cups reported by validation. Skip the user XYZ prompt — bbox sampling + PreForm's surface projection handle placement. If PreForm reports "no surface found" for a model, surface that to the user and offer add_drain_holes (hand-placed) as fallback.
estimate_print_time — report time and material usage.
save_form to the chosen path. Skip the confirmation if the path is new; ask before overwriting an existing file.
Optionally save_screenshot to a .png next to the .form for preview.

When to use this vs formlabs-print

User mentions "save", "prepare", "set up", "draft", "preview" → this skill.
User mentions "print", "send to printer", "kick off the job" → use formlabs-print.
Ambiguous → ask once which they want.

Things to avoid

Don't use TaskCreate for this flow. Short linear pipeline; overhead.
Don't loop retries on IMPORT_PRODUCED_EMPTY_SCENE — that error means the STL is genuinely malformed and the post-import verification caught it. Tell the user, stop, and let them open the file in PreForm to diagnose.
Don't invent machine_type or material_code values. Use list_printer_types / list_materials to get real values.
