Correction for minute 13:45 The trolley may start wobbling with time due to wear and tear. Most Laser Engravers have an eccentric nut that allows you to easily adjust the tension of the rollers. All you need is a small wrench often provided with the machine and twist the nut until the trolley feels tight enough and runs smoothly.
Thank you soooooooo much!! All of my angles were off, nothing wsa ever 90 degrees. Quite shocking to find that my left and right side of the Y-axis were actually 4 mm off! I applied the technique with the belts, and now I can use my laser cutter again. You are a life saver.
I have the problem that you indicated in the minute 11:37, double printing and deformed circles, I did everything you indicated but it remains the same, is there something to configure in grlb?
You are very precise in your explanation, I have a problem a little bit different, if you can help me to solve it I will appreciate it very much. I have a Neje machine and tryed to cut 3 mm MDF, it is ok in the Y but in the X doesn’t cut, I can send you pictures of the hexagon and in the 4 vertical inclined lines it cut, I but in the horizontal up and bottom do not. In advance thank you. Roberto
For me it was double image when I first assembled my x7 pro. It was just loose belts on the Y gantries. Thought it needed a lil slack but it needs to be not too tight but tight
i upgrade my laserhead to lu2-10a but has 3mm difference on y axis ... i draw 20x20mm square it cut wll de 3.2mm plywood but when i see the result x axis is 20mm and y is 23/25 mm.. comw rexomedation ?
Hi, thank you for your comment. I guess your y axis steps/mm is not set correctly. Make sure the $101 in the grbl configuration is set correctly; for most desktop laser engravers the value should be 80. I hope it helps. Ciao
Hi, BrieannaKroeger-eb1ys; thank you for your comment. Which software are you using? This may be caused by either the use of current/custom origin instead of absolute or you are facing dimension problems. Perhaps the design is in mm, and the software is set to inches. Does your project start the framing from where you point into the software and then crash or not? let me know CIao
I am experiencing ghosting on the bottom half of my 4x4 inch image. I'm going to try this method of re-tightening the belts, but I'm also hearing stories of it being caused to the diode not focusing. Do you have any videos on that topic? Thanks
Hi, @AbzentMinded, thank you for your comments. If by ghosting you mean line skips, this is usually due to slack belt, but in an image engraving the machine scans bottom to top, therefore this should not occur. Another problem could be thermal where the laser module basically drops in power while working to cool down, however in your case this does not explain the phenomenon in the first bottom half of your image unless the bottom half is darker or has more details, and therethore the laser works more there. Let me know the model of your machine and the engraving parameters of your image, also confirm if the image is darker or fuller at the bottom. Ciao
@@MiddleRoomWorkshop I'm using an ortur laser master 2 pro s2. I've tried different versions of the image, even cropped and blended 2 versions of the image. Ended up scrapping the idea and went with other images (sports logos) and they work great. Guessing it's just a bunk image to begin with?
I have a laser engraver with 2 stepper motor on y axis and I had irregularities when drawing circle. Problem was that the current was set to high from the drivers. I set it low enough not to lose steps and now it is smooth again. Maybe it helps someone
Hi, I am not sure and don't know which is x -axis tension problem or y - axis problem? How can you tell from the test results, I would like to learn that.
Hi, lewy; thank you for your comment. cipry1010 gave you a correct hint; look at the direction of distortion. the simplest way is to fill engrave some text in standard Horizontal lines; if it comes out okay, it will exclude the x-axis since usually is the fast axis used for fill engraving. Another method is to engrave a circle. In general, if an axis is fine, the diameter in that direction should be correct. I will give you a simple example and procedure to understand how to read tests. First, home your machine, then set the custom origin or position you circle project anywhere up and to the left of your home or laser; by doing so, you make sure that the leading meaning is the section of the belt going up and to the right is under tension. Say your circle engraves clockwise starting at 12 o'clock with both belts under tension on the leading side. The first quadrant, i.e. the arc up to 3 o'clock, should be perfect, then the x-axis will start reversing its direction while the y-axis continues going down, If you notice a flattened section after 3 o'clock, it means that the x-axis needs tightening. If the circle continues smoothly, meaning that the right side up to 6 o'clock is perfect, then you have no problems with the x-axis and measuring the vertical diameter should correspond to the diameter you set the circle. Now going on, from 6 o'clock, if you notice a flattened section or a variation in the shape of the curve, your y-axis or axes or the rod should be tightened. Check the preview where the circle starts, so you can apply this procedure. If you are using LightBurn, you can select the starting point and choose the direction of the engraving. With LaserGRBL is not as simple but by applying the same logic, you can figure out the problem I hope it helps
@@MiddleRoomWorkshop Hi, thanks for your explanation in details, that's helpful. 😀 I think your explanation to read test results is worth to make a video to public because there is no people or forum explained as you did. Your way of sharing is brilliant!
Hi, thank you for your comment. A blurred engraving may be caused by a dirty lens or a wrong focus height; I suggest checking the lens and cleaning it if necessary first. A simple way to verify the least cleanliness is to raise the laser up all the way, fire at low power (0.5 to 2%) on a surface and check if the projection is scattered, if it is the lens needs cleaning or replacement. If the problem is not the lens and you are setting the focus correctly, I suggest running a focus test to verify whether the height is correct. Here is an old video showing how to perform a focus test. ruclips.net/video/GTuH27e4kWM/видео.html Let me know, Ciao
@@MiddleRoomWorkshop Thank you. I'll try it. 😁. I contact Customer service, they said it caused parameter software. But I Follow parameter instruction. And they said it cause timing belt is loosen in y axis right and left. But my timing belt is tight in all axis. And solve that I never try is from you. May be it caused the lens and focus. Thank you 😁

Your test file and walk through of all the various issues led to me fixing my problem.. Thank you very much for this video
Fantastic explanations. To the point, with clear examples
Thanks a lot. It worked. I was going to throw my machine away. But you saved my 1500 $. Thanks again. 🎉
Very useful! My problem was a loosen belt. Thank you so much!
Thanks for the video ! After long search your Gantry explanation fixed my issues very easy since they forgot to screw it together right :D
Amazing video! Thanks for sharing this information. Really helpful 👍🏼

Thanks a lot. Very ussefull for my zbaitu laser engraver
Thanks for the helpful video.
My question is how did you get the machine to engrave in a circular manner vs x axis motion then step up in the y.
Thank you. Finally I found it 7:54

You said a better model to avoid problems.
What model or brand would you consider to be better to avoid some of this.
I try and I try and I can't get it to work right. I get distorted shapes no matter what I do. Very frustrating.
For me it was double image when I first assembled my x7 pro. It was just loose belts on the Y gantries. Thought it needed a lil slack but it needs to be not too tight but tight
thank you!
