Laser engraver & laser cutter repair in Wichita.

Usually it is one of five things, roughly in order of how often: dirty optics, alignment that has drifted (moving or bumping the machine will do it), a focus lens put back upside down after cleaning, coolant running too warm, or a tube near the end of its life. A failing high-voltage power supply can look the same. Measuring output power at the tube and again at the head tells you quickly which one it is.

The reliable sign is measured output. If you need a higher power setting than you used to for the same cut, or a power meter at the tube reads well below its rating and keeps dropping between checks, the tube is on its way out. Weak or flickering output, cracks in the glass, and cloudy or contaminated coolant are other warning signs. Before replacing it, rule out optics, alignment and the power supply, because they cause the same symptoms and cost much less.

Look at them at least once a week and clean them whenever you can see residue. Machines cutting a lot of wood or acrylic need it more often. Use lens tissue with reagent-grade isopropyl alcohol or a cleaner made for laser optics, drag the tissue across the surface rather than scrubbing, and check that the lens goes back in the right way up.

Distilled water. Tap water carries minerals that raise conductivity and leave scale, and both shorten tube life. Keep the reservoir clean, change the water on a schedule, and set the chiller to the temperature range your tube maker specifies while keeping it above the dew point in the room so the tube does not sweat. If the machine sits somewhere that freezes, ask before adding anything, because some additives raise conductivity.

Yes. Those are the kinds of CO2 machines most shops around Wichita run, along with other import cutters and engravers using Ruida or similar controllers. I am not affiliated with or authorized by any of these manufacturers. If your machine is still under the maker's warranty, check with them first, since third-party work may affect it.

No. I do not open up fiber laser sources internally. I work on everything around the source: the galvo head and its boards, the F-theta lens and protective window, calibration and EZCAD. If the source itself has failed, I can confirm it with measurements and help you find a qualified service provider, so you are not shipping a machine off only to learn it was the lens.

Look at the mirrors and lens weekly and clean them when you see residue. Keep the chiller topped up with distilled water and watch its temperature. Empty the crumb tray and clean the honeycomb before debris builds up, since it is a fire risk. Make sure the exhaust and air assist are running whenever the laser is. Write down the power setting you use for a standard test cut, so you notice when it starts creeping up. And never bypass an interlock to get a job out the door.

Yes. You fill in the service request form, then we do a video call where you show me the fault, the control panel and the interlock wiring. Afterward I send a short written summary of the likely cause and the parts worth having on hand. It works anywhere, and the fee is credited toward an on-site visit if the job turns into one.

Yes. Laser tube replacement includes measuring the old tube first to confirm it is actually the problem, installing the new one, adjusting the mounts, realigning the beam path, and measuring output power afterward. Both measurements go in the service report so you have a baseline for the new tube.

I diagnose glass CO2 high-voltage supplies on site or on the bench. The first job is proving whether the supply is the fault at all, since a dead tube, an open interlock or a missing enable signal from the controller can look identical. Where the supply is repairable I repair it; where it is not, I give you the replacement spec. Supplies can be shipped or dropped off for bench diagnosis.

A service call is a flat fee that covers the trip and the first block of diagnostic time, then hourly after that. Parts are billed at cost plus a stated markup, and the invoice shows both numbers. Everything is quoted before work starts.
