Hi. I had a problem with double images and found out about the overscan settings and sorted that. But now, as you can see above, the left and right edges are fine, but the middle section is still giving double imaging. I am only a newbie to this so am completely at a loss. Its a Creality Falcom 5w
Changing Overscan will not fix double images.
Tell us in detail what you have done to make the sides look good.
What speed and power settings are you using?
Show us your cuts layers window and your preview window.
Screenshots are MUCH preferred over cellphone pics.
Overscan settings were taken from this youtube. https://www.youtube.com/watch?v=dF8CgAjgUH4&t=612s. My first print similar to this one was really bad, Following this advice corrected a lot of it.
As for the sides, I have done nothing. That’s just what happens now with the overscan settings.
Just tried to upload screen and failed. However, apart from overscan settings, its basic setup with 3000 speed and 85% power.
WIN+shift+s opens the snip tool. Drag a box around what you want copied to your clipboard. Come back here and Ctrl+v will paste your clip.
For now, working without being able to see your settings, it would seem most likely that you have mechanical slop in the system.
If you turn your picture 90 degrees, does the problem follow the rotation or does it stay with the x axis?
It never hurts to slow down the laser while you are having problems.
Does the source have this? I would think these peaks should line up.. There is also evidence the whole image is off as some edge areas have less density.
If looks off, are you using crosshatch and or bi-directional scan? You can eliminate an offset issue by turning bi-directional scan off. The job takes twice as long, but it might help you. If you have crosshatch enable, might want to turn it off.
Thank you JKwilborn. The original image doesn’t have these twin peaks. This is the issue I am trying to resolve. As for the less density in areas, I assume this is an issue from burning bamboo. Other materials seem fine.
Did you try part of the image with bi-directional scanning disabled?
I have been trying to but it seems lightburn doesn’t have the option to turn bidirectional scanning off. The nearest I can find is to use offset fill, but this doesn’t give me a good quality finish.
Thank you to everyone who contributed to this. Following the advice seen on another similar question, I I tightened the belt that the laser runs on and it seems to have corrected it. Early days yet, but certainly better than it was. Bit disappointing when I only bought the n thing new in April. Anyway, once again, thanks to you all.
Constant vigilance is required when using high repeating motion machines. A tiny bit of weakness can rapidly become noticeable slop.
It is part of the hobby.
