I set 260mm/s and 15% max power. If the machine starts with the shoe the path to engrave is very short, resulting in many direction changes in a short time. If to fast, the quality suffers. For this part I can not set the speed any higher. However, for the rest of the image the speed could doubled.
Probably there is no out of the box solution for that. I do already use the fill all forms at once option.
If you want to have different settings, you need to cut the graphic into two parts.
But usually, you use overscan for this. Set the overscan high enough for the laser to reach the desired speed. Then small parts look identical to the larger ones.
Can you adjust the overscan setting? Default on my machine is 2.5%. I have gone up to 8% on occasion. That really makes a big difference for my GRBL machine.
Use as much overscan as you need to get your results, but don’t over do it as it will add that much travel time and length to the whole layer..
No, with Ruida controller this option does not exist. But, thanks to @misken I found the solution with some research.
For anyone stumbling across this post.
You want to open your machine settings(wrench / screwdriver icon), and switch to advanced options tab. There you want to change X engrave acceleration value.
lower value results in more overscan and longer engraving time. But it reduces the wobble.Mine was set to 50000 and with now 12000 there is a huge difference. Try it out and use the preview function of lightburn to see the time and overscan increase.
Sorry, I need to edit that. What I described above is only for lightburn preview function.
You must navigate to lasertools → machine settings > read from controller.
This are the settings you want to change. My X accelatrion Value was set to 100000. setting it down to 25000 is much, much smoother to solve the described problem in post #1.
Don’t forget to write the changes to the controller and change the parameter for preview in lightburn to the same value
