I’ve been contending with the static buildup… Thanks for the information. LightBurn is a GREAT program... GREAT community with plenty of helpful info. special hats off to the Louisiana Hobby Guy.!!! And all the rest of folks that take time to do videos, been very helpful to someone just getting started in this hobby.!!!
Phenomenal software, and the fact it's a one time license purchase including upgrades and not a monthly subscription makes it affordable for hobbyist like myself.
Thank you I was trying to fix the weak laser output for two hours now such a simple fix. Really good peace of sotware for that price honestly!
Great and straight to the point
Hey, thank you so much! The $30 value has delayed me for a week. Changed it to 1000 and I feel I got my laser back. :) Even bought new lenses but that obviously didn't help, haha. Thanks, you're a champ!
Thanks for making videos like this. Saves a lot of time spent on forums.
Glad to hear. That is the goal :)
Can't wait for Lightburn tips and tricks for FIBER LASERS!!! Please say Lightburn for Fiber is being released tomorrow!
Weak laser fix helped me!!! Thank you! 👍🏻
Thank you so much for this video! My device's S Max Power was set to 255 and should have been 1000. That small change has made a world of difference.
Glad to hear this got your machine sorted.
Helped a lot - thanks
Thank you very much for this video👏
I had problems with my Longer Ray5 10W not cutting through 3.7mm plywood even with 100%, 80mm/min and 3 runs.
After watching your video i recognised the $30 value was offset so i matched them up and now its cutting through like butter.
Awesome, that is great to hear.
Great info. Very helpful info!
Thank you , enjoyed the Info
Best video on the channel! I'll be directing a *lot* of people to it!
Awesome! Thank you.
1st solution was the solution, thanks man!
Thank you so much for this video! Very helpful!
Glad to hear!
Thanks
Thank you. Your video is very helpful. I've been using LightBurn with Neje Master 2S machine for sometime and this video have reminded me about several issues I encountered. All of them was fixed after receiving reply from LightBurn Forum. Recently I encountered a problem when engraving Ceramic Tile. After about 1.30 hours of burning the engraver stopped. One of your recommendations in the video is to connect a ground cable. Since engraving machine cables are the 9mm round input jack which have two wires and if I connect a ground cable on the engraver machine where should I connect the other end. Thank you
Excellent 😊
Thank you so much for this video. I got a new laptop and installed Lightburn, and suddenly, my laser would not even cut 2mm basswood. Came across this video, and discovered that it was the S Value causing the issue. A link to this video should come standard with every laser engraver.
Glad to hear that this did the trick, its a fairly common issue.
Just bought my first diode laser and it didn't seem to be cutting very well. checked my S-Value Max, and it was off. now my machine is cutting like a champ. Thanks!
Glad to hear that did the trick 👍.
Creative video, keep it up, thanks for sharing :)
Your a star! Fixed my issue with in the first minute 😅
Awesome! Happy to hear :)
My problem was the cable.. solved the problem in 5 minutes, god bless you =D
Glad to hear you were able to find the culprit!
I have a Longer Ray 5 10w and one problem I have is that cut settings that work on the test card don't work the same in a project. One thing I've noticed is that sometimes vertical cuts will burn through while horizontal cuts won't. I thought maybe it had something to do with grain pattern but it even does it on MDF.
Literally solved my problem in less than 10 seconds. Thank you!
tank you for the tip(s-value max) now i can cut material 4 times faster😀
Hey! I have the Sculpfun S9 and I am having the problem described in 3;00 , I tightened the belts but when there are quick and sharp movements a normally symetrical print turns unsymetrical - I do not know what to do :(
I have a quick question about how the laser engraves, mine doing a grid will randomly engraves the squares but when the project completes it is what it was supposed to be. So if lasering a grid it works in a random pattern instead of cutting in rows and columns how do I fix that?
This was so useful. Thank you so much.
I was convinced my laser had to be replaced as suddenly it was not cutting what was easy before. The S value was the culprit which I am not sure why suddenly wasn't matching the machine's value. How do I ensure all the correct settings are set? This sort of thing had happened before with certain parameters were not correct. How do you ensure everything is optimally set up to get the best from your machine?
Glad to hear you where able to figure out what the issue was. Unless there was a firmware update that could have changed the value on the machine there shouldn't be anything that would switch it without manually editing it in LightBurn. Some manufacturers have a reset option in the firmware but if things are working as expected now I really wouldnt recommend poking around the firmware more than necessary.
I just bought an Ortur Laser Master 3, and it keeps stopping half way through. I'm just testing it out and this is all new to me, and I'm disappointed so far. I'll follow the advice in the video. Thanks.
Any luck with this? Normally if a job stops there is some form of output in console. If you are still having issues contact our support - support@lightburnsoftware.com
@@lightburnsoftware7189 Thanks. No still no joy. I have to make a video and take some pics, for the tech advisor, from where I bought it, and send. If I get the problem sorted out, I'll post on here. Maybe I should post a video on here. I have to get hold of a screen recorder to make the video. I have do it tonight.
We're having an issue as well. Using Lightburn, Laser Master 3. Laser loses connection before finishing. First tries with the stock cable got through about 10٪ before dropping connection. Checked the computer settings, bought a new, well shielded cable, and were now getting about 50% through before it loses connection.
@@krystalpurdue1644 I tried a new cable, not a cheap one, but even worse. I am in contact with the tech people where I bought the machine. If we find the answer, I will update you. I put a video on my channel. I was advised to make another video, but this time have the window visible where all the laser info can be seen as it is lasering. So I will be doing that today. If you find the answer, please update us. Thanks.
@@krystalpurdue1644 I had a message today, and this worked for me it seems. I did 3 engrave tests, all worked perfectly. Try this below. I will do more tests this week just to be 100% sure, then make another video to let other people know. Keep in mind I already disabled all sleep settings on my computer. Try this.
Right click start menu on windows -> device manager
Expand DISK section -> Right click Espreessi Mass Storage USB Device -> Disable
Restart the machine.
I just got lightburn and I'm still trying my best to learn it thanks for the hobby guy and of course you guys! How do I know if my d1pro has all the correct codes?
Do you mean error codes? As long as the output appears correct I wouldn't worry about it too much. (unless the machine is throwing an error). This video is meant to give you a grasp on what could cause errors and what to check if you do run into one of them.
@@lightburnsoftware7189 No so far I've been really happy! I still got a couple weeks on my free trial. Still trying my best to learn! My business logo is very complex. I made it into an SVG outline, but it still doesn't look right for cutting boards & stuff. Maybe I'll just plaster a sticker on it?
Hi, thank you for the video. I just purchased the tts-20 pro but it won’t engrave or cut anything. I have tried different settings and power lvl woth different designs all it does is try to do the pattern and I can see the laser light moving but it won’t engrave or cut anything.
Did you make sure that the focus is set correctly for the material? Also take a look at the section under "Power output is not the same as other software (GRBL)" in our troubleshooting article:
docs.lightburnsoftware.com/Troubleshooting-Output.html
If you are still having issues reach out to our team - support@lightburnsoftware.com
Ground issues I know how to solve that make sure you scrape away some of the paint for powder coat in the area that you're connecting your ground the powder coat cannot give you a good ground just take a razor blade or something small for a Dremel and scrape away a small amount of the powder coat away from the frame.
I like to practice my light burn but I cannot get rid of the device menu that keeps on popping up and will not go away. How do I get rid of it and continue practicing or designing what I wanna work on and send it to my server and open it from the shop. I don't know if the free license is what's blocking it from happening if that is the case then I will go ahead and purchase I have lots of experience with Photoshop I'm hoping that this is like Photoshop in the way I see layers. First time using.
I noticed the program that comes with the laser is not very involved it does not have a lot of features laserGRBL
Hello, where can I find the silver bar to set the focal length please, ours was list in the move😢....I appreciate your videos and time!! Ty!!!!👍👍👍
If you lost the metal focus bar you can reach our to the laser manufacturer and see if they sell them separately. It would probably be easier to find the focal length and just cut a focus stick/jig out of wood.
I'm having a Y axis issue where when I go to frame, it just goes left and right and seems to be stuck going up and down. It's like a shake when it tries to move. I tried tightening and loosening the belts
Is it only know moving in the Y direction when framing or the machine just will not move in the Y axis? If the laser is not moving in the Y axis, the first thing I would check is the cables. Check that the stepper motor cable both on the Y motor and Y connector of the board is seated properly.
I have the sculpfun s9 with lightburn. The laser moves very slowly during framing and cutting, but moves at a normal pace otherwise. We've adjusted the speed in lightburn, but nothing seems to work. Any ideas?
The framing speed and travel speed is set in the move window. The text box labeled speed between "distance" and "z-speed" is the one to adjust. The actual speed of the engrave (line or fill) will be set in the cuts/layers window.
This is not specifically a Lightburn question, although I have purchased and do use Lightburn. I have an Ortur Lasermaster 2 pro, which I upgraded with a Neje a40640 laser module. It has been working great for the past year. Then today I added the extension kit to my Ortur to make the bed 400 x 800mm. Now the laser module does not burn as hot. I tested the the module in test mode and it works fine, but when I run a job through Lightburn the laser seems very weak. This laser module comes with a digital readout and even though it says 50% on the readout, it is more like 10%. When I set the board to test mode and adjust the PWM to 50%, it reads 50% and outputs 50%.
It's all the same wires, so I am wondering if there is a setting in Lightburn that can adjust the PWM or TTL or output frequency (I am not really sure) that will match the output of the board.
Totally perplexed.
Just as a side note, I checked all the settings you mentioned, and also updated Lightburn and even the Ortur firmware to the latest releases after watching your tutorial, but it's still not working.
I just got my Sculpfun S30 10w. Its giving error 5 - hominh cycle not enable in Grbl setting. How it can be fixed ? Please guide.
How do I adjust travel speed? What in referring to is speed of the laser when it's not firing. It's really annoying having the entire job go really slow cause I set the laser speed low. Is there a way to speed up the process so it slows down to firing speed only on areas that need engraved/cut.
I believe there is a setting to ignore white. I saw something about that on a Louisiana Hobby Guy video. Sorry, I don’t recall which one.
Hello
When I frame a object to engrave my laser head frame the same at different postions slithly left or right or up and down. Doest frame same position when I frame the same file more than once
Do you have your travel speeds set to high? If the motors are skipping steps that could cause this. I would lower speeds, and also check both belt tension as well as the set screws on the stepper motor idlers are tight.
Hello! Great video! Can you help me? My laser cutter doesn't make circular or curve movements, when tracing, cutting or framing! Do you know how can I solve it? Salutes from México! Thanks!
It makes regular lines to trace curves. When framming, it does the same movement.

need help connecting my ATZER to my Mac, its not recognizing the cable or port...please help
Please help I don't know what happened? I've been practicing with my 20w xtool. All below 50% power. I decided to try the infrared for a little bit on some metal had to go to 100%. Now I plugged back in my 20w and the light is just really bright and big? When I use the fire button it's fine. When I go to engrave it changes? I have reset and unplugged what now? No updates on XCS or LB. I don't think I would have cracked my glass, I don't know how? Anybody have answers? 🤔😒
Houston we have a problem. New machine, just yesterday I was doing piercing on stainless steel, everything was okay. Today there is no piercing. Same material and same settings. What do I have to do? Sculpfun s10 bought on AliExpress. Cleaned the laser, it turned out to be a torn gasket, replaced it, did not help. I don't know what to do. Maybe the lens is burned out? How can it be replaced?
I would start by checking our grbl guide for output issues: docs.lightburnsoftware.com/Troubleshooting-Output.html#power-output-is-not-the-same-as-other-software-grbl
There are a couple of things to try in there. If you are still having issues and believe it may be hardware related, I would next contact the manufacturer.
my laser dot is getting big even after normal focusing.......any help please
Do you by chance know why when I turn my laser controller off it still has power to the controller board. It will only power completely off if I remove the usb cable. I suspect a ground issue somewhere but do not know where it would be. The power supply is 3 pronged so I am grounded there and all connections are properly connected.
This is fairly normal depending on the controller. Many of them can be flashed over USB so the 5v from the cable will power on the controller. Usually it will just be the board though and not fans or the laser module.
I did the whole set up. My laser worked a good few minutes then stopped. Now it won't turn in. I jus bought the machine. I even did a reset. I don't understand what could possibly keep the laser from turning on. Any info would help.
When you flip the switch for power is there any LED indicator? On mine the red emergency power switch had been pushed down so check that. Otherwise, it could be faulty Power Supply, or an issue with the mainboard.
Any idea on Wainlux jl7 start up, my fan runs nothing happens can’t see a laser and just get a clearing flash message on app??
Is it connecting to LightBurn? Is there any error message being displayed in the console? We wont be able to give feedback on their app but it looks like it is running GRBL firmware so it should work with LightBurn.
My sculpfun s9 laser suddenly stoped when working.
Hello, I just set up my Longer ray 5 10W laser with an air assist. When I hit the frame on LightBurn, my laser just goes to the left off of the small piece of wood. I set the dimensions to the size of the test wood piece but it's just going to the left even when I hit start. Thank you for any help you can give. I am a beginner.
It sounds like your origin or start from mode is not correct. We have a video covering the different start from modes and how they work here: ua-cam.com/video/aphiLTUWcjE/v-deo.htmlsi=cSRlQtpT1Pi2zZ5h
Thank you!@@lightburnsoftware7189 Just seeing this reply. Going to try this and see if it works.
My diode laser has been stopping midway and resetting itself. This has really frustrated me. How do I ensure that the grounding is working. Or how can I detect where the exact problem is?
Hello, im using ortur master 2
Just instaled a new 80 w laser
And it wont stop burning on travel nor when it finishis the job iz Just goes to zero and still working and burning the zero point. I have followed instructions and have cheked the $$ and it was already at 1 . Is there any other problem?
Was this an issue with the previous laser module? Run through the items listed under "Short Version" here:

My Device Settings for the Workspace setting for X & Y do not match the console output for $130 and $131. On the console it shows $130=432 and $131=406 like you have in this video. When I try to update in the console and type $130=430, enter it returns with "ok", but upon confirming with $$ it still shows $130=432. Is this a problem that there is a mismatch and if so, how do I update it?
It should be an issue unless you are trying to squeeze those last 2mm out of your work area. The stock firmware may have been updated to not make this something you can edit. The only reason I could think of would be a 2mm tolerance buffer.
I need Help!! my laser was working fine but recently it began to do something weird. it doesnt last in the correct spot. for example, i designed a heart shape with a name inside of it. it did the heart shape great and then wrote the name outside of the heart. ruined my entire project. second time it worked fine. next project, same problem. the first round went bad and second time was good. why is this happening ?
ive been getting this problem where the power light keeps blinking on and off and the fan cant seem to stay on, and so i cant print anything
Is there any output in the console? If you are able to connect I would see if the laser is throwing an error.
It could be an issue if the power source exceeds the laser's current consumption ?. For example, requirement is 12V at 4A, but my power source is 12V at 10A.
As long as the voltage is matching, the diode will not draw more current than it needs.
@@lightburnsoftware7189 Thanks !
Hi , my aufero laser keep flashing and don't reconnect within Lightburn. Is there any button for connecting Laser? Thank you
There is a lock on the Aufero when you first connect. Try clicking the stop button in LightBurn or typing $x into the console.

@@lightburnsoftware7189 i fix it thanks
My sculpfun going not good,it suddenly moving but,no cut and just small power amount of laser going out even i put it in full 100% power,why ya?
I would check our guide under power output to see if the S-Value Max is correct or that constant power is set: docs.lightburnsoftware.com/Troubleshooting-Output.html
If it is not a hardware issue it is likely one of those two.
@@lightburnsoftware7189 dont really understand what it is,but i try to understand okay,tq for info,i will check
I have an issue where the laser fires when moving (very little power maybe less than 1%) how can I solve this? I suspect it is a static build up
There are a number of issues that could be causing this.
Knowing what laser you are using will be helpful along with if it was always doing this or it is something that recently started.

@@lightburnsoftware7189 I have a custom frame with a NEJE motherboard and a Sculpfun S30 Pro 10W module, and my garage outlets are not grounded, so I guess there's a lot that can be causing this. I'm in the process of grounding the frame and passing new cables to ground the outlets and see if it persists
After entering $32=1 to switch to laser mode, is this permanent or I have to perform this switch to laser mode every time I power on the machine?
In settings of lightburn these $parameters can be changed easily and saved on laser as well. Regarding your question - it takes 2 minutes to check by yourself. Would do it, but unfortunately will be back at home only after 3 months.
They should stick, but it also may depend on the way your contoller/firmware is configured. Easiest way to test would be to change the value and then power cycle your machine. Upon reconnecting enter $$ and see if it retained the $32=1 value.
hi i am new to this my laser is not working the laser come on and off like it runing but nothing happening pls help
So you are able to run the job but the laser turns off while running? We will need some additional information to troubleshoot. Please create an email with the specific machine, project file, and a short video showing what is happening and send it to support@lightburnsoftware.com

I have problem that the lazer stop working in the middle of the work
So my machine just engrave half of the work all time .. and i do not know why this is happening
Is the machine grounded properly? For engravings there have been instances with the machine building up a static charge during engraving causing it to stop after sometime. What does the console display when this happens? Please send this with any additional info surrounding machine, console output, which jobs are causing it to support@lightburnsoftware.com
@@lightburnsoftware7189 thank you for your reply
Do you have a video for grounding the machine

my laser is to weak to engrave anything, just started recently what is going on?
If it just started recently it is possible something happened with the laser itself on the hardware side. There are a couple of things to try in our documents on output: docs.lightburnsoftware.com/Troubleshooting-Output.html#power-output-is-not-the-same-as-other-software-grbl
You can also try to rollback your LightBurn settings to a previous version in case something was tweaked: ua-cam.com/video/OvuR0Uj1kL0/v-deo.html
My laser starts off fine then stops moving up and down, how can I fix this?
If it is not moving up and down I would check the wiring for the y axis motor, the belts, and the motor pulley. Belts should be tight, motor pulley should be tight and not able to rotate on the motor shaft, and make sure the wire connectors are fully seated. If you are still having issues after that email our support support@lightburnsoftware.com

Give up on this…Black background small white text, hard work for some needing spectacles aka glasses…especially when viewed on iPhone / iPad size devices.
It is going to be tough to follow along some of the software screen recordings from a mobile device due to scaling. Manual subtitles have been added as well as on screen text to help with this. Subtitles can be turned on within the video player.
Is it OK to manually move the laser head when the machine is powered on? Do the servo motors still report their digital location when moved by hand to a desired start point? Thanks for your advise. Specifically Algolser Alpha model.
These motors have no feedback at all, so moving them by hand will cause the machine to lose its position.
@@lightburnsoftware7189Thanks for the shout..
@@lightburnsoftware7189BUT, IF you were to use "CURRENT POSITION" for your starting point, then, it would/should not matter. Only if you try to use "ABSOLUTE COORDINATES" would the servos not know where they are/were since a manual move would corrupt the calibrated "HOME" location. Do you agree?
@@ainttakenanyshit - Correct, it shouldn't matter, but it would mean that the machine could not enforce limits and may collide with the side rails, whereas if you only jog using the jogging functions, all of these "software based" enforcements will still work, preventing damage to the machine.
@@lightburnsoftware7189You're correct. Use the move arrows and be safe. This may be old news, but, I normally use current position with a laser crosshair for pin point positioning. I just learned today that when I tried to burn a project that used the entire 12 x 12 inch board, using the absolute coordinates, is IS necessary to turn OFF the laser pointer offset because it throws off the entire build area. Scratch one board, turned off the offset, and had a good burn starting at X=0 and Y=0.... Others that may just be starting to utilize a crosshair may not know/remember to kill the crosshair offset....
Thanks
