When I watch videos it shows the laser moving in the X axis only on the preview.
When it’s moving on my preview it’s showing the laser moving on the x and y.
Example if I have letters it shows it on the preview doing each letter 1 at a time. When videos I watch it does all the letters at once on the X axis only. If that makes since
You have a fundamental misunderstanding here. The head travels on the x-axis only, but the rotary IS the y-axis and does turn instead of the head. So there is no difference between normal operation and rotary from the LightBurn perspective. You will see the same preview in both cases. The only difference is, which physical axis is used.
I know this can be difficult to imagine in the beginning, but once you get used to it, things get clearer
When I look on YouTube and they show the preview the laser travels the x axes and lasers turn on at each letter. Y rotates the Rotory and the laser goes back across lasering each letter and so on. Mine just shows the laser head traveling the y and x doing each letter separate. Wish I could take a video.
I think you are talking about the fill modes here. Select “fill all shapes at once” in layer settings, then LightBurn won’t do letter by letter but go over the full text at once. This is also recommended for rotaries.
I have both a chuck rotary (came with fiber machine) and a PiBurn wheel/roller type rotary.
I always use the scan option with the wheeled rotary… if I want a vector engraving, I’ll use the chuck, if it fits. I use which ever I deem best for the operation, be it fiber or co2.
