Co2 Laser Troubleshooting Guide - Troubleshooting Poor Cut Quality

[@loriscott8037]

You solved a problem I've been baffled by for 5 months! I have yet to see another video that explains to clean the lens on the tube. After watching this video, my 150W went from cutting corrugate at 80 mm/sec to 200 mm/sec. Thanks for the video!

[@jimidero]

6:55 my honeycomb bed has some mm(even 4mm) difference in many spots. How can i fix it?

[@colinbousfield6381]

Well explained. I have another conundrum. I am getting straight but erratic dimension cuts on the y axis (this suddenly started after 7 years of work. For example if I cut a box 3mm high x 20mm wide and cut say 6 of these at once I can find the height can vary from 3mm to 3.1mm to 2.8mm and no linear degression, first can be 3mm second 3.1mm next 3.1mm and last 2.8mm. checked steppers, swopped stepper controllers, looked for belt and pully damage etc. Bit stumped

Hello Matt, I would like to know please how much the rear transmission shaft of your machine measures that is observed in the minute: 3:57

[@MWLaser]

Approx. 1570mm from motor on the left to bearing on the right

[@Mekaproyects]

@@MWLaser Thank you very much Matt, just what I needed

[@gasman9845]

Thx for the video Matt all your videos are so easy to listen to and are packed with great information.

[@MWLaser]

Thank you

Hi matt, my machine is not producing laser while going to cut the sheet

[@a.opristineautomotiveindus6911]

Good day, I have a laser machine but the power interface switch keep blowing anytime I changed the fuse. what is the solution to the problem of power interface switch keep blowing

[@elizeduplessis7920]

Morning. Hope you well. I so hope you can help me. When cutting with my co2on any material Ihave an uneven cut. . If you stand in front of my machine. The 2 thirds to the right side cuts perfect. But the 3rd to the left is very bad and don't cut through what can be possibly wrong. TIA

[@zawilious]

i have a 150w-180w reci tube , i'm noticing huge drop in cutting effectiveness, i've checked every detail, all mirrors and lens are clean and super alligned, tempereture of chilled water always below 25degree celcius , and while cutting my milliammeter is showing 2 to 4 milliamps drop from previouses values, and even after i increased the power or reduced the speed , it is not performing well, i've had about 600 hours of laser ON time, but the age of the tube is around 4 years. at first i suspected that my power supply may be the cause, but if my ammeter is reading good milliamps values does that mean my power supply is definetly good ?

[@gme273]

G/day Matt , what's purpose of the Cone at the bottom of the lens.

[@wwrite]

Very timely video for me, I just came into the shop yesterday and was experiencing a decrease in cutting performance. I cleaned the lenses, mirror 3 & 2 but didn’t see anything on mirror 1 and didn’t think the laser could have anything on it. I will check today to ensure. I was thinking tube replacement as I have been running my stock K40 as a production machine for the past month and figured it wasn’t made for running 8+ hours a day like this. I will be cleaning all surfaces that the laser beam comes in contact with or through and see if things change. I wish I had a way to test the power supply’s output to ensure it was operating correctly. I know I have been pretty hard on my K40 this last month running it nonstop.

[@MWLaser]

You're welcome, I hope you sort out your cutting issues. Cheers

[@turboflush]

3 years.. Wow. Is there a way to check the output on the laser without having previous ma specs?

[@MWLaser]

not sure what you are asking - [e-mail]

[@Mekaproyects]

Great video, thank you very much for your tutorials Matt

[@MWLaser]

Glad you like them!

[@can5projects563]

Hello Matthew my laser was gutting fine showing 18 mA but now it just shows 10 mA on the mA meter no matter what power I'm using

[@MWLaser]

May be laser power supply or tube issue.

[@can5projects563]

what can I do? how do I check? what it is?

[@paulaferreira4540]

Hello Matt, when I cut a rectangle, the x and y (especially the y) are not perpendicular, is there a way to calibrate it? thank you very much and congratulations for your excellent videos and time spent.

[@MWLaser]

you could check that the X & Y axis are at 90 degree angle to each other and not out of alignment

[@lucaturazzi]

Hi Matt!! I just found your channel and thanks for all information you chare with us. It's been very useful!! We have a question and maybe you can give us a solution, please! We have a 300w fold CO2 tube, and we tried to install and fail. Used two diferentes power supply, but it doesn't start both of tube together. Always one or another. Giving to us half of the power. May be used the wrong power supply? We can even sent videos or whatever information you ask for!! Very expensive tube and nobody know how to turnt it on with full power...

[@MWLaser]

They require 2 x psu to operate

[@Byteman72]

Hi Matt and thank you for all the useful information you provide on this channel. Can you please advise how you go about lubricating the linear bearings? My machines bearings have these small grease nipples that I cannot find an attachment for.

[@MWLaser]

most linear bearings are a sealed unit with packed grease, no additional grease required. keep linear rails clean with a rag. if you need more advice email [e-mail]

[@joesmith2465]

how many passes and power should it take to pass thru 1/4 (6mm) plywood? I have a 60w OmTech brand I think its not cutting like it should

[@wwrite]

My K40 used to have no issues cutting through 3mm birch at 15mA and 10mm

[@MWLaser]

Not sure with a 60w, I actually have not attempted 6mm on one. Maybe this can be answered by someone who has. However for comparison on the 80w I have cut in single pass with low speed and power around 25mA. Cutting power and speed for different types of plywood vary, if it is a hardwood ply it will take more than a single pass.

[@ahrihz]

Hi matt do you have the file for your lens focal gap? Thanks.

[@MWLaser]

No I didn't save it but you can draw up in LightBurn in just a few minutes

[@katsuragisan1]

Hello Matt,great video like always and very helpfull.I have one question about my axis.On Y Axis my machine,when I start,it starts on Upper Left position.But it is 10mm almost shorter than it was in the beggining and X axis overlap honeycom also about 10mm on one side.When travels on controller it shows normaly 900x600 and on RD is adjusted work size to 900x600.I was thinking that limit switch is doing this but moving this switches nothing happens.What could be problem?Thanks in advance.

[@MWLaser]

this is not something I can assist with via youtube comments. email info to [e-mail]

[@bogdahn689]

Thank you, very, very , very much ! This will help us a lot !

[@MWLaser]

Glad to hear that!

[@PaulM-ec7kd]

youre amazing! such a great teacher. are you in melbourne? do you do "house calls"

[@MWLaser]

Yes. Located in Melbourne Eastern suburbs. Onsite service available, training also available in our factory.

[@joefox9383]

Thanks for the video. I'm new and learning so every bit helps. I just got a Blue Elephant 5'x10' laser with a 175w RECI laser. It cuts wood, acrylic and cardboard great. I was rather disappointed to find that it won't cut 28ga sheet metal. Do you think something may be set wrong? I've seen other KZbin videos of 150w co2 lasers cutting 16 ga mild steel like butter.

[@MWLaser]

does your machine have metal cutting head ? you cannot cut with standard setup

[@beltramaker]

Hi Matt, excellent explanation, as always, I replaced the motor and calibrated my laser, I have to organize myself with the times for your intervention. in the meantime, thanks again, I'll send you an email. Greetings

[@MWLaser]

Thank you. Anytime 😊

[@Lasercuttinglk]

Great Video and easy explanations..good job

[@MWLaser]

Thank you!

[@briangagen8436]

Thank you for the insight.

[@MWLaser]

No worries!

[@jonathanoeijoeng]

another great video!. Thanks. Btw, I'm considering cloudray or reci laser tube 90-100w. Which one you will recommend? I know both come from same company but would need your advice. Thanks

[@MWLaser]

From your two options, I would recommend RECI, I however have Cloudray Laser tubes in two of my machines and they are performing extremely well. Have you considered HM Laser tubes? they are also a high quality laser tube manufacturer and there may be a local distributor in your country. Cheers Matt

[@jonathanoeijoeng]

@@MWLaser thanks for your reply. I cannot find HM here in Indonesia but i can find hardray brand. Have you heard about hardray?

[@MWLaser]

No I haven't

[@ronintate770]

you prolly dont give a shit but if you are stoned like me atm then you can stream all the latest series on Instaflixxer. I've been streaming with my girlfriend for the last days :)

[@boonenikolas4923]

@Ronin Tate definitely, I have been using Instaflixxer for months myself :D

[@Jaidevbhoomiukwale]

Hello sir, I'm having some issues on my laser tube, if you can provide me your mail id I can send you video on mail. On my laser tube the silicon pipe (water in on tube) having hole and laser power coming out from there. I replaced the water in tube after after 2 days again having a small hole laser power coming out from that hole. Can I fixed that? Please help

[@MWLaser]

email [e-mail] - send photos too so I know what you are dealing with. Thanks

[@Stefanos.Tsokaras]

Great, thank you Matt!

[@MWLaser]

My pleasure!

[@matthewlewis5631]

Hey Matt, thanks for the useful tips. Can I ask, are the screws for your Z axis ball screws or ACME lead screws? I couldn’t quite tell from the shots but I suspect they are ball screws - do you find them to be better then the acme screws on the red and black? Less wobble when lifting the bed?

[@MWLaser]

Yes they are Ball Screws. Much better than the Acme on Red and Black, definitely a smoother motion and provide better stability on the bed.

[@timtimmons3115]

Honestly it’s hard to watch a video when 60 seconds in I feel like I’m being deceived when you insert a dirty swab into the laser lens and say “as you can see here that we’re starting to get some of that dirt out”
