Thunder Laser Nova Plus 35: A Buyer‘s Checklist for Your First CO2 Laser

So You‘re Getting a Thunder Laser Nova Plus 35? Here’s the Checklist I Wish I Had

If you're looking at the Thunder Laser Nova Plus 35, you're probably in the same spot I was two years ago. You need a reliable CO2 laser. You want to cut and engrave acrylic, wood, maybe some leather. And you don‘t want to spend weeks figuring out the basics.

I manage purchasing for a 12-person fabrication shop. We’d outsourced acrylic cutting for years. When we decided to bring it in-house, I got the green light on a Nova Plus 35. This checklist covers what I learned — the steps I'd tell myself if I could go back.

There are 5 steps. Start here.

Step 1: Unboxing and Setup — Don‘t Skip the Grounding Check

Machine arrives. Crate looks solid. Feels like Christmas morning. But slow down.

What most people don’t realize is that the most common setup issue isn‘t alignment — it’s electrical. The Nova Plus 35 draws about 15 amps. If your shop has older wiring, you might trip breakers on startup. We had to install a dedicated circuit. That added $350 to the “budget” before we even cut anything.

Checklist for this step:

• Verify power requirements: 110V or 220V? (The Plus 35 is typically 110V in the US, but check your specific model.)
• Ground the machine properly. Not just plugged in — physically grounded.
• Level the frame. Uneven surface = misaligned optics later.
• Install the exhaust system before you power on. Seriously. Laser + fumes = bad day.

I assumed the “standard” electrical setup would work. Didn’t verify until the machine arrived. Cost us a week of downtime. Don‘t be me.

Step 2: Lens Selection — The Thunder Laser Lens Kit Isn’t Optional

The Nova Plus 35 ships with a standard 2-inch lens. That‘s fine for general engraving and cutting up to 1/4 inch material. But if you’re doing acrylic laser engraving or fine detail work, you'll want options.

Here‘s something vendors won’t tell you: the “free” lens that comes with the machine is just the starting point. You’ll want at least one additional Thunder Laser lens for specific jobs. For us, the 1.5-inch lens made a huge difference on acrylic edge clarity.

What I bought alongside the machine:

• 1.5-inch lens — better for fine engraving, smaller spot size
• 4-inch lens — better for thicker materials (up to 3/8 inch), but slower
• Lens cleaning kit — cheap insurance. Dirty lenses = inconsistent power.

Add about $200-300 for a good starter kit. Check prices against Thunder Laser‘s official site (thunderlaser.com) to verify.

Step 3: Material Testing — Your Settings Will Not Be the Same as YouTube

You’ve downloaded SVG files for laser engraving. You‘re excited. You hit “Start.” And the first cut is either a charred mess or doesn’t go through.

Welcome to material testing.

I spent an entire weekend dialing in settings. It was frustrating. But it saved us from ruining $400 worth of acrylic in one afternoon.

Here‘s my method:

1. Cut a test grid. Use LightBurn’s built-in test tool. Vary power (50-100%) and speed (10-50 mm/s). Label each square.
2. Start with recommended settings. Thunder Laser’s support team can provide baseline numbers for common materials. But treat them as starting points.
3. Keep a material journal. Write down settings for every new material. Paper, acrylic, wood, leather. It‘ll save you hours later.

One tip: for acrylic laser engraving, lower power and higher speed gives a frosted look. Higher power and slower speed cuts through but might leave burn marks. Test it yourself. No two batches cut exactly alike.

Step 4: Workflow Integration — Where the Hidden Costs Live

This is where my TCO thinking kicked in. The machine price isn’t the final number. Not even close.

When I calculated total cost to get our first job out the door, I found these hidden items:

• Software licensing. LightBurn costs ~$120. One-time. Worth every penny.
• Exhaust hose and blower. The machine has a port. You need to connect it to something. Another $150-200.
• Air assist. A small air compressor ($80-100) improves cut quality on wood and acrylic.
• Training time. Budget 2-3 days for a new operator to get comfortable. That‘s $1,200-1,800 in labor if you bill it.

The $4,500 quote for the Nova Plus 35 turned into about $5,200 with accessories and software. Still cheaper than a competitor’s base model. But the difference matters when you're quoting a job.

Step 5: Daily Operations — A Quick Maintenance Routine

Lasers aren‘t set-it-and-forget-it. Here’s my 10-minute daily routine:

1. Check the water chiller. Temperature should be 20-25°C. If it‘s warm, wait before running.
2. Clean the lens. Even if you don’t see smoke residue. Do it before every job run.
3. Inspect the honeycomb bed. Remove debris. Fire hazard if it builds up.
4. Check the exhaust hose. Kinks or blockages will ruin your cut quality.

Skip this once, and you'll spend an hour troubleshooting a bad cut tomorrow. Trust me.

Common Mistakes to Avoid

I‘ve made all of these. Don’t be like me.

• Assuming 10W can do everything. Can a 10W laser engrave metal? Usually not. CO2 lasers don‘t engrave metal well unless it’s coated. The Nova Plus 35’s 80-100W CO2 tube cuts wood and acrylic great. But metal engraving? You'd need a fiber laser.
• Not checking the Thunder Laser lens options. The stock lens works. But for detail work, the 1.5-inch lens is a game-changer.
• Buying cheap SVG files. Free or $1 files might look fine on screen. But the layers might be wrong, or the paths might be open. Spend $5-10 on a trusted designer's file. Saves rework.
• Skipping the fire watch. Never leave a CO2 laser running unattended. Paper and wood fires happen fast. Keep a fire extinguisher rated for electrical fires nearby.

To be fair, I started this process thinking a laser cutter would just “work” out of the box. It kind of does, if you define “work” as “cut something after an afternoon of setup.” But a smooth workflow? That takes planning.

Bottom Line

The Thunder Laser Nova Plus 35 is a solid machine for small shops. It’s competitive on price. It cuts acrylic beautifully with the right lens. It‘s not plug-and-play, but no serious laser is.

If you follow this checklist, you’ll avoid my mistakes. You'll save time. And your first project will actually turn out right.
