Diode 14-Day Onboarding Path
This path is diode-specific. The Diode tab has 20+ modules. This is the order to read them in for a brand-new diode owner, paired with progressively harder test pieces. Two weeks turns the reference manual into a course. Mirror of the Fiber 14-Day Path, calibrated for diode hardware and material set.
Before you start: shopping list
Order these so they're on the bench when you begin. The accessories portion of this list (air-assist pump, painter's tape, OD-rated diode glasses, fire extinguisher, calipers, IPA, microfiber cloths) is collected in the Kinetic Carving Amazon Storefront if you'd rather get the basics in a single pass.
- 3mm and 6mm birch ply: 10 sheets each. The diode's bread-and-butter material.
- Veg-tanned leather scraps: 4-6 oz weight, ~10 small pieces.
- Slate coasters: 6-pack from a craft store. Excellent diode-friendly substrate.
- Stainless steel coupons: 50×50mm or similar, ~10 pieces, brushed finish.
- LBT-100 or dry moly (molybdenum disulfide) spray: for marking stainless.
- CerMark or dry moly spray: for marking bare aluminum (diode + CerMark = black mark on aluminum).
- Anodized aluminum coupons: black + one color, 10 of each.
- Painter's tape (3M ScotchBlue 2090), masking for wood char control.
- Honeycomb bed: if your machine didn't ship with one, get a 400×400mm aluminum honeycomb. Game-changer for cuts.
- Air assist nozzle + small compressor / aquarium pump: improves cut quality dramatically.
- OD 5+ glasses rated for 450nm blue (not optional, diode beams scatter widely).
- Fume extraction: at minimum a window fan; better an inline duct + carbon filter.
- Loupe / 10× magnifier for inspecting marks.
- Fire extinguisher (CO2 or ABC) within arm's reach. Diode + wood = real fire risk.
Week 1: Foundations & first cuts
| Day | Read | Do |
|---|---|---|
| 1 | Diode Lasers, What & Why · Optical vs Marketing Watts · Safety | Unbox, level the gantry, install the air-assist nozzle. Verify the work area is clear and ventilated. No engraving yet. |
| 2 | Lightburn Setup for Diode · Frame & Origin | Install Lightburn, configure as GRBL/GRBL-LPC, save device profile, set bed dimensions, run "Hello World" on scrap wood. |
| 3 | Focus, Three Methods | Master focus with the focus card / fixed standoff. Run a Z-axis ramp test to verify true focus distance. |
| 4 | Daily Workflow in Lightburn · Layers, Cut, Fill, Image | Run your first 3×3 test grid: power × speed on 3mm birch. Photograph and label each cell. |
| 5 | Wood Settings | Dial in production cut + engrave settings on 3mm and 6mm birch. Save as Material Library entries. |
| 6 | Leather & Fabric | Engrave a leather coaster. Try painter's tape masking on a second piece for char control. Compare. |
| 7 | Stone, Slate & Paper | Engrave 3 slate coasters. Different design per coaster. These become your gift portfolio. |
Week 2: Beyond the basics
| Day | Read | Do |
|---|---|---|
| 8 | Coated Metals (LBT-100, CerMark, painted) | Mark a stainless coupon using LBT-100. Mark a bare aluminum coupon using CerMark. Document settings. |
| 9 | Acrylic & Plastic | Try to engrave a black acrylic piece (works on dark cast acrylic, limited but possible). Understand what your machine CAN'T do. |
| 10 | Photo Engraving | Engrave a portrait on birch ply using Jarvis dither. Compare against the slate version (slate often wins for diode photo work). |
| 11 | Diode vs CO2 vs Fiber Decision Matrix | Read only, start identifying which jobs you'd take and which you'd refer out. Build your shop's "do" / "don't do" list. |
| 12 | Production Workflow on Diode · Material Library Files | Set up jigs for repeat parts. Save 10 validated recipes to your Material Library. Run a 5-piece batch of identical wooden tags. |
| 13 | Trace Image · AI Workflow | Convert a customer-provided photo into a vector path using Trace Image. Generate a wood-burn-friendly design with AI tools. |
| 14 | Maintenance · Troubleshooting | Clean the lens, level the rails, inspect the belt. Run your favorite production job and document timing for future quotes. |
What you'll have at the end
- A diode you actually trust to run a production batch unattended (well, supervised. Never truly unattended).
- A Material Library with 10+ entries you've validated yourself.
- ~15-20 sample pieces (wood, leather, slate, marked metal) for customer portfolio shots.
- Honest answers to "can you make THIS?", you know exactly which jobs your machine can handle and which to refer to a CO2 / fiber friend.
- Confidence to take on Etsy orders, local craft fair pieces, and small B2B projects.
Skill checkpoints
| Skill | Self-test |
|---|---|
| Focus | Can you reach reliable focus on an unfamiliar wood thickness in under 60 seconds? |
| Cuts | Can you cut 6mm birch with edges clean enough that no sanding is required? |
| Engraving on wood | Can you produce 10 identical wooden tags with no visible char variation? |
| Slate photo | Does your slate-coaster portrait read clearly from 1m viewing distance? |
| Coated metal mark | Can you mark a stainless coupon with LBT-100 cleanly enough to pass a fingernail rub test? |
| Recovery | If a cut doesn't go through, can you diagnose (focus / speed / power / lens dirty) in under 5 minutes? |
The diode-specific pitfalls to watch for
- Fire risk is real. Diode + wood + no air assist = embers. Never run unattended; keep a CO2 or ABC extinguisher within arm's reach. Air assist also speeds engraving and dramatically improves cut quality.
- "Watts" lies. See Optical vs Marketing Watts. A "20W" diode probably outputs 5-6W optical. Don't compare "watts" across brands without optical-output verification.
- Spot size matters. Cheaper diodes have larger beam spots, coarser engraving detail, especially on photos. Higher-end (xTool S1, Sculpfun S30 Ultra, OneLaser etc.) compress spot size but cost 2-3× more.
- Bare metal won't engrave. Period. You need spray (LBT-100, CerMark) or coated/anodized substrates. If you mostly engrave bare metal, plan to upgrade to fiber.
- Cut speed is slow. A CO2 cuts 6mm birch in 1 pass at 10mm/s; a 20W diode cuts the same in 4-6 passes at 2-4mm/s. Plan production timelines accordingly.
Next steps after Day 14
- Etsy SEO Playbook, list your first 5 products on Etsy.
- Customer-Supplied Pricing, quote your first CSI job correctly.
- Marketing & Selling Laser Work, Instagram / TikTok process videos.
- Pricing & Customer Intake, broader pricing math for laser shops at any tier.
- Revisit this path after 30 days. The Week 1 material will feel embarrassingly basic; that's the point.
Diode philosophy
The diode is a "cheap to start, slow to scale" laser. Treat it as a gateway: master it, ship 100 paying jobs on it, save the proceeds, and use what you've learned about your shop's actual demand to decide whether your second machine should be a 60W CO2 (for acrylic / faster wood) or a fiber (for metal). Most shops outgrow diode within 12-18 months, that's not a flaw, it's the path.
