My friend, I really thank you from the bottom of my heart for sharing all this information. I thought I would die with the machine out of calibration and now I have it perfectly calibrated thanks to you! greetings from Chile
Hello, I have the problem that the 9-point calibration is not dimensionally accurate. I also use a 200mm lens. If I calibrate my laser to 200x200, a 200x200mm square created in LB is also 200x200mm on the laser. A very small square of 5x5mm also fits. But a 100x100mm in LB is 102x102mm on the laser. I suspect that my lens is not linear. Or what could be the reason for this? EasyCad uses a 25-point calibration. This means that I also get a correct result at 100x100mm. Kind regards, Michael
Hi Guys Have you tried doing a 300mm lens? I cant get the job to fit on my work area. Does not matter what size I tell the software to run it is way off my work area so I cant do the test. Forunatly Cloudray have supplied core files for all size lenses but I am sure these would be a generic correction and I would like to get my machine spot on. I have searched and found others asking this question but so far I have not found an answer.
The LightBurn team is always working on improvements, there's a reason we love em lol. It worked okay before, even in beta before that tool was public, just not perfect. It's biggest issue was scale really, and thats now not an issue with the added scaling tool. With having the added tool to specifically address that to tune to perfection, its totally solid. I'm sure they'll keep pushing the envelope for improvements though which is always a good thing.
@LaserEverything this is the reason why I really like this companies. They listen and improving things. And in the end, the price is very affordable and actually very cheap for business owners.
damn, i was curious why my jobs are just incorretly burned (focal distance seems to be right, but sizing is still incorrect). thank you for clarification. guess i'll need to redo the calibration all over again.
You wont need to do the whole calibration if you've got the first portion done already for that lens, you can just do the scaling portion with a test square of an expected size, and what size it actually comes out. When you input the two values it should adjust the scale for you and sort that out :) Just make sure your testing at a reasonable size and keep it centered to the lens, and that'll give you the best consistent accuracy across the average of the whole lens.
@@LaserEverything actually i do, because i get incorrect square dimentions (messed up somewhere). using 180x180mm square i get one side 2-3mm bigger than another.
Hello, I'm new to your course, and I wanted to say thank you, you helped me and I learned a lot from you. I have only one question, I received with my machine a "markcfg7" file . Although I didn't use EZCad at all I directly imported the file into LightBurn. So do I still need to do these actions such as: Lens Correction , Lens Distortion, Timing and Delay..? Or does the "markcfg7" file already contain all these settings and I don't need to touch anything? This confuses me a bit. Thanks again!
That file is a great way to get going quickly with settings directly from the factory but they are not always the most accurate and do not include many of the aspects covered in these videos. For you to have a strong foundation of understanding and get the most out of your machine I would strongly encourage you to follow each step and find your own values for the various machine configuration options we cover. Hope that helps!
@@LaserEverything Thanks for the quick reply. I will do it! Do I have to do the process once throughout the entire period of using the machine or are there cases where I will have to repeat it? Can I save it? Thanks again for the big help!
@am-ge2kj much of it will remain the same, though there are some instances where you may need to retune some things. These are also tuned per lens, so these values won’t exactly match if you have or buy additional lenses.
I am having difficulty with trying to set up a 200mm lens. i go through the step process and set it up to do 180mm box. When I frame it x=250 and y= 262mm. I lowered the size of the box and it becomes an octagon shape. I tried changing the scale percent but no luck. Stuck like Chuck.
Well, there can be a few things that cause this. This tool and process tunes you, but If for example you have project mark (cylinder correction for LB) enabled, it’s going to warp your design intentionally, which will be exceptionally noticeable on a flat item since it’s expecting to mark around a curve. I would say that’s probably the most frequent cause, but ultimately if you can mark both a circle and a square line, and both are stretched either on the x or y axis, you need to revisit the scale portion of the video later in the video to specifically handle scale correction, which it doesn’t always get right during calibration through the first tool and why they have the second tool there. Another factor, be sure your material is flat, doesn’t have anything holding up or causing tilt to one side. If your tower allows for tilt adjustment, you’ll also want to verify that and rerun the calibration, if the lens isn’t on a parallel plane to the work bed it’s going to cause this and other problems as well. Hope that helps! If you’re still stuck, definitely join one of our linked communities and make a help thread so it can be looked into more thoroughly if needed.
thank you @@LaserEverything , will go back in and look after the weekend. Much appreciate you taking the time to reply. I am a member, sadly not a paying one, but love the support and stuff I can see.
