The Novanta Laser Order Checklist: How to Avoid Costly Mistakes (From Someone Who's Made Them)

I'm the guy who handles our team's laser cutting and engraving orders. I've been doing it for about 7 years now. In that time, I've personally made (and documented) at least a dozen significant mistakes, totaling roughly $5,200 in wasted budget and rework. Most of them were avoidable. Now, I maintain our internal checklist to make sure no one else repeats my errors. If you're ordering from a company like Novanta or any industrial laser service, this is the list you should run through before hitting "submit." It's not about theory—it's about preventing the specific, expensive problems I've seen happen.

Who This Checklist Is For & When to Use It

Use this list if you're ordering laser-cut or laser-engraved parts, prototypes, or finished products from a B2B supplier. It's built for situations where the cost of a mistake is more than just an annoyance—it's wasted material, missed deadlines, and blown budgets. Think orders for acrylic panels, metal components, engraved signage, or custom fixtures. It's less critical for one-off, disposable test pieces, but for any order that matters, run through these steps.

There are 5 core steps. They seem simple, but skipping any one is where the trouble starts.

The 5-Step Pre-Submit Checklist

Step 1: Verify the File is "Production-Ready" (Not Just "Looks Good")

This is the biggest trap. Your file looks perfect on your screen in Illustrator or AutoCAD. That means nothing to the laser. Here's what to check:

Checkpoint A: Vector vs. Raster. Are your cut lines actual vector paths? In my first year (2018), I made the classic rookie mistake: I sent a high-resolution PNG for a cut line, thinking "it looks sharp." The laser's software saw a blurry edge. The result was jagged, inconsistent cuts on 50 acrylic nameplates. $380 straight to the scrap bin. Lesson: All cut and engrave paths must be closed vector shapes. No exceptions.

Checkpoint B: Line Weights and Colors. Most laser software uses color coding (e.g., red lines = cut, blue lines = engrave). Confirm your supplier's color-to-action mapping. Is it RGB 255,0,0 for cut? Or a specific spot color? I once ordered 100 pieces where the engraving didn't happen because I used the wrong blue. We caught it before production, but it caused a 2-day delay.

Checkpoint C: Scale is 1:1. Sounds obvious, right? In September 2022, I opened an old file, didn't check the document units, and submitted. The parts came out at 80% scale—completely useless for the assembly. That error cost $890 in material and a 1-week project delay. Now, I always place a 10cm x 10cm square in the file corner as a visual scale reference. The vendor usually ignores it, but it's my final sanity check.

Step 2: Double-Click the Material Spec (Beyond Just "Acrylic")

Saying "3mm acrylic" is like saying "a red car." It's not enough. You need the specific grade.

Checkpoint A: Cast vs. Extruded Acrylic. For laser cutting, cast acrylic gives a cleaner, flame-polished edge. Extruded is cheaper but can melt more, leaving a rougher edge. If edge clarity matters (for displays, lenses), you must specify cast. I learned this after a batch of light guide panels looked hazy. The vendor used extruded because it was their default. My fault for not specifying.

Checkpoint B: Metal Alloys & Coatings. With metals, the alloy and surface finish drastically affect the result. Anodized aluminum engraves differently than bare aluminum. Stainless steel vs. mild steel have different cutting parameters and potential for discoloration. For a recent order of 20 stainless steel labels, I had to confirm they could engrave through a powder coat without damaging the substrate underneath. It took a test piece, but it saved the whole batch.

Checkpoint C: Material Thickness Tolerance. "3mm acrylic" might be 2.8mm or 3.2mm. If you're designing interlocking parts, that tolerance matters. I don't have hard data on industry-standard tolerances, but based on our orders, my sense is you should design with a ±0.2mm gap for press-fit parts. Always ask the vendor for the actual thickness of their stock.

Step 3: Define Tolerances & "Acceptable" Imperfections

Lasers are precise, but they're not magic. There will be minor imperfections. The question is: which ones are acceptable? Getting this wrong is where relationships with vendors get strained.

Checkpoint A: Kerf Allowance. The laser beam vaporizes material, creating a cut width (kerf). It's small—maybe 0.1mm to 0.3mm depending on the material and laser. If you need a part to be 10.0mm after cutting, your drawing must compensate. Forgetting kerf on a tight-tolerance mechanical part is a guaranteed fit issue. We've caught 47 potential errors using this specific checklist item in the past 18 months.

Checkpoint B: Engraving Depth & Consistency. How deep is "deep"? For serial numbers, you might need a minimum depth for legibility. For decorative engraving, consistency across the part might be key. Specify if possible (e.g., "minimum 0.1mm depth"). If you can't specify depth, ask for a sample image of a similar job.

Checkpoint C: Backside Damage (Dross & Discoloration). Cutting, especially metals, can leave residue (dross) on the back or cause heat discoloration (a heat-affected zone) on the edges. Some is normal. You need to state what level is unacceptable. Is light discoloration on the back of a hidden bracket okay? Probably. On the face of a consumer product? No. Put it in writing.

Step 4: The Logistics & Timeline Reality Check

This is where the time certainty premium comes into play. A cheaper quote with an "estimated" delivery can be far more expensive than a pricier one with a guarantee if you're against a deadline.

Checkpoint A: Build in a Buffer. The vendor says "5 business days." I plan for 7-8. Why? Because "5 days" often means 5 days in production, not including file review, material sourcing, or shipping. In March 2024, we paid a $400 rush fee to get a job in 3 days. The alternative was missing a $15,000 trade show. That rush fee bought certainty, not just speed.

Checkpoint B: Shipping is Part of the Spec. How will the parts be packed? Laser-cut acrylic scratches easily. Will they use protective film, interleaving paper, or just throw them in a box? For delicate or high-finish parts, specify packing requirements. I once received a box of beautifully engraved plaques… all scratched from rubbing against each other in transit. That was a $450 lesson.

Checkpoint C: Quantity Verification. You need 137 pieces. Do you order 137? I usually order 140-145. Why? There can be breakage in shipping, or one piece might have a tiny flaw. Having a few extras is cheap insurance against being 1 piece short and needing a whole new production run. The marginal cost is low; the risk mitigation is high.

Step 5: The Final Pre-Approval (The "Cool-Off" Check)

Do not submit the order right after you finish the file. Walk away for an hour, or better, until the next morning.

Checkpoint A: Print a Physical Proof (at 100% scale). Tape it to the wall. Look at it from a distance. Does the layout look balanced? Are any text elements too small? A screen hides scale issues. This has caught countless errors for us.

Checkpoint B: Read Every Word Aloud. For engraved text, serial numbers, logos—read them character by character. Your brain autocorrects on screen. Your ears won't. We once shipped 1,000 items with a typo in a website URL because no one read it aloud.

Checkpoint C: Send a Final "For Approval" PDF. Before the vendor starts production, request a final PDF proof from their RIP software. This shows exactly how their system interprets your file. It's your last chance to catch color mapping errors or scaling issues. It adds a day but has saved us thousands.

Common Pitfalls & Final Notes

Don't Assume "Standard" is Standard: Terms like "standard finish" or "standard turnaround" are meaningless. Always get the specifics in writing on the quote.

Communication Channel Matters: For complex jobs, a phone call or screen share is better than 50 emails. A 5-minute call in Q1 2024 clarified a tolerance issue that emails had muddled for days.

Your Experience May Vary: My experience is based on about 200 mid-range orders with industrial suppliers like Novanta for prototyping and mid-volume production. If you're doing ultra-high-volume runs or one-off art pieces, some priorities might shift.

The goal isn't perfection—it's predictable, repeatable results. This checklist turns the chaotic, error-prone process of laser ordering into a series of simple, verifiable steps. It's the documentation of my mistakes, so you don't have to fund your own learning curve.
