Repair pricing

Three tiers. Same transparent approach as our cutting work.

Step 1

Tell us what is wrong

Email or call with your machine model, symptoms, and any recent changes (new tube, new firmware, machine moved). We will tell you whether it is something we can solve remotely or needs an on-site visit.

On-site (SoCal)

$150/hr

+ $1/mile travel

We come to your shop or studio. Travel charged by the mile from our shop at 1319 S. Los Angeles St., Los Angeles, CA 90015.

On-site (rest of US)

Inquire

Nationwide on-site

We travel for on-site repair anywhere in the United States. Pricing depends on travel and scope — email us with your location and we will quote it.

Remote (US)

$120/hr

Zoom or phone

Anywhere in the US. We walk you through diagnosis and (where possible) the fix.

Why not just fix it yourself?

Six things people learn the hard way. We've seen all of them.

1. Lasers aren't plug-and-play

Most issues are rooted in a delicate balance of optics, firmware, electronics, and mechanical alignment. Fix one without checking the others and you create a new problem.

2. Scripted remote support misses the real issue

Big-box manufacturers run scripted diagnostic flowcharts. Useful for known problems. Less useful when something doesn't fit the script.

3. The cause isn't always the symptom

Weak cutting could be a degrading power supply, a grounding issue, firmware pulse timing, or lens coatings breaking down. Replacing the wrong part doesn't fix it.

4. One wrong swap cascades

Replace a power supply on a system with a real grounding fault and the new supply blows in days. We check the full chain before we touch anything.

5. High voltage is genuinely dangerous

CO₂ laser power supplies carry lethal voltages. Capacitors hold charge after power-off. We've seen what happens when someone forgets that.

6. YouTube skips the hard parts

Tutorials cover the easy diagnostics. Wiring quirks, intermittent firmware faults, and weird controller behavior live outside the videos. Experience fills the gap.

Common questions

Do you repair all brands of CO₂ lasers?

Almost all. We regularly service Epilog, Boss Laser, Thunder Laser, OMTech, Universal Laser, Trotec, Full Spectrum, Rabbit Laser, Dremel, Orion Motor Tech, Ten-High, Flux, xTool, Aeon, AP Lazer, and most Chinese-import CO₂ cutters and Chinese-import fiber lasers. We also service diode lasers (xTool, OMTech, generic). We do not service Glowforge or name-brand fiber lasers.

How much does a repair cost?

On-site repair in Southern California is $150/hr plus $1/mile travel from our DTLA location. We also offer on-site repair anywhere else in the US — pricing depends on travel and scope, so email us with your location for a quote. Remote diagnostics via Zoom or phone is $120/hr, anywhere in the US.

Can I drop my machine off at your shop?

No. We do not accept machines at our DTLA shop. All repairs are performed on-site at your location or remotely via Zoom or phone.

Do you offer remote support?

Yes. Remote diagnostics via Zoom or phone, anywhere in the US. We can walk you through diagnosis and (where the fix is doable without a technician on-site) the repair itself.

How quickly can you come out?

Response time depends on location and current workload. To get you a real answer fastest, tell us the model, symptoms, and any recent changes when you reach out.

All brands serviced

If it cuts with a laser, we have probably worked on one.

Over a thousand repairs across two decades. Most major American CO₂ brands, the bulk of common Chinese imports (CO₂ and fiber), and a growing number of diode lasers.

American CO₂

Epilog, Boss Laser, Thunder Laser, OMTech, Universal Laser, Trotec, Full Spectrum, Rabbit Laser, AP Lazer.

Chinese imports

Most common Chinese-import CO₂ cutters and Chinese-import fiber lasers. Ruida-controller machines a specialty.

Diode & other

xTool, Aeon, Dremel, Orion Motor Tech, Ten-High, Flux, and a growing number of diode laser brands. If your machine is not listed, ask.

On-site, anywhere in the US

We repair on-site nationwide.

Most of our on-site work is in Southern California, but we travel for the right job. If your laser is down anywhere in the country and remote diagnostics will not get you back up, we will come to you. Inquire for travel and pricing.

SoCal — flat rate

$150/hr + $1/mile from our shop at 1319 S. Los Angeles St., Los Angeles, CA 90015. Same-day or next-business-day for most jobs in the LA basin.

Outside SoCal — inquire

We travel anywhere in the United States for on-site repair. Pricing depends on your location and the scope of the job. Email us with your city, machine model, and symptoms and we will quote travel + labor.

Try remote first

Many issues — software, calibration, controller errors, settings — solve over a Zoom call at $120/hr. If we cannot fix it remotely, we will tell you what is needed and quote on-site travel from there.

Service · Remote diagnostics

Remote CO₂ and diode laser diagnostics, anywhere in the US.

Your machine is down and you're not in Southern California. We diagnose and (where possible) walk you through the fix via Zoom or phone. 1,000+ repairs across most major brands. $120/hr.

What we can solve remotely

Remote-fixable

  • Software / firmware bugs
  • Settings & calibration
  • Diagnosing a non-cutting laser
  • Workflow & file prep issues
  • LightBurn setup & configuration
  • Operator error troubleshooting

Needs on-site or shipped parts

  • Laser tube replacement
  • Power supply replacement
  • Mirror or lens replacement
  • Stepper motor swap

How remote diagnostics work

1

Tell us the model and symptoms

Email, form, or phone. Mention any recent changes (new tube, new firmware, machine moved).

2

We schedule a Zoom call

We'll schedule and diagnose at a time that works for both of us.

3

We diagnose live

Screen-share LightBurn or your controller software, walk through tests, check error states.

4

You get a clear answer

We fix it on the call, or we tell you what part you need. Honest assessment, no upselling.

Remote diagnostics pricing

Remote (US)

$120/hr

Zoom or phone diagnostics. Anywhere in the US.

On-site (SoCal)

$150/hr + $1/mile

If remote isn't enough and you're in SoCal.

Remote repair — common questions

What if you can't fix it remotely?

We tell you exactly what part you need and where to get it. If you're in SoCal, we offer on-site service. If you're outside SoCal, we point you to the right reference materials or service tech.

What controllers and software do you support?

Ruida (LightBurn), Trocen, M2 Nano, Universal, Trotec, Epilog, and most Chinese imports. If your controller isn't listed, ask.

Can you walk me through replacing a part myself?

For some parts (mirrors, simple optics, belts), yes — over Zoom. For high-voltage parts (power supply, tube), we strongly recommend on-site service or a local tech. CO₂ laser power supplies carry lethal voltages.

How quickly can you book?

Tell us how urgent in your initial message. We'll schedule the call as soon as we can.

What do I need on my end?

A laptop with Zoom, your machine powered on (or accessible), the controller software open, and a phone or webcam to show what you're seeing.

Common problems — quick troubleshooting.

Two of the issues we see most. If these don't fix it, that's what we're here for.

Laser losing power

Cuts taking longer, struggling with materials that used to cut easily, or uneven engraving depth — usually an aging CO₂ tube, misaligned or dirty optics, a power-supply issue, or poor cooling. Test by firing pulses and comparing burn marks, or by re-running a file that used to work. Voltage testing should only be done with proper training — these supplies carry lethal voltage.

Ruida–LightBurn connection errors

When LightBurn won't talk to a Ruida controller: restart the laser and the computer, confirm LightBurn's device profile matches your controller, try a different short shielded USB cable and port, and on Ethernet make sure the PC and controller share an IP range. Reinstalling the FTDI driver from LightBurn's support page fixes many cases.
