Creating a CNC Sign from Start to Finish — Design to Cut

Walk through a complete sign project — from blank board to finished piece. This covers the full workflow you'll repeat for every sign.

Step 1 — Material Selection

Thickness: 19–25mm for wall signs. Flatter grain = cleaner carve.

Step 2 — Surface Prep

Sand to 180 grit before mounting. Flat stock = consistent cut depth.

Step 3 — Design in Vectric Aspire

1. New project → set material size
2. Import or draw text and artwork
3. Use Node Editing to adjust letter spacing
4. Add a border/frame vector if desired
5. Preview in 3D view

Step 4 — Toolpaths

Pocket toolpath — clears large background areas

• 1/8" flat end mill, 0.5mm DOC, 40% stepover

V-Carve toolpath — text and detail

• 60° V-bit, feeds per material above

Profile toolpath (if cutting shape)

• 1/8" compression bit, full depth, tabs at corners

Step 5 — Cut Order

1. Pocket first (removes bulk)
2. V-carve (adds detail)
3. Profile last (releases part)

Step 6 — Finishing

1. Remove from machine, pop tabs
2. Sand top surface lightly (220 grit) — don't sand into carves
3. Blow out carved channels
4. Stain or paint if desired
5. Apply a topcoat (wipe-on poly, lacquer)
6. Add hardware for hanging

Common Beginner Mistakes

• Zero at top surface (not bottom) — always zero at top
• Too deep V-carve on thin stock — set flat depth limit
• Forgot to convert text to curves — text can shift if font not found
