Move along boundingbox ("Preview")
Some people might want a preview of the boundingbox of their design on the material. We could add a "Preview" button next to the execute button that only sends the outline of the complete job. The preview power could be 0% power and speed could be100%, but of course it would be great if this was configurable. I would place this button left to the execute button.
(I still think the VisiCam solution is a better one, but it's more work to setup)
I like this feature very much and want it myself, so as soon as I have time, I will implement it.
Quick Solution: Create a new Laserprofile with a name like "Preview" or "Move Outline" and select the "use outline option". Also disable any optimization by selecting "FILE" as optimization algorithm. In the laser-settings for that profile just select 100% speed and 0% power. Works for me. This also has the advantage, that it does use a tighter outline than just a bounding box. Didn't test it with complex shapes though, so it may be, that it will also move around "inner" shapes.
I tested the 'use outline' feature. But used the algortihm "NEAREST". It does something strange then:
This design has lots of numbers and text using a single stroke hershey font. The glyphs often are paths (that have a start and an end.)
To me it looks like a 'close all paths' feature. :-)
This is what I had loaded: (Photo above was taken before the laser finished)
Ruida devices apparently have a specific command built-in for such a preview feature. I retrofitted a control panel on an OMTech Polar (which features a 6442S controller). It has a "Frame" button that (like in LightBurn) runs move commands to show the bounding box of the object for the currently selected job.
I suppose this feature depends on a correct bounding box being sent to the device as part of the job, which the Ruida driver does.
As discussed in #711 VisiCut could just send a job doing the same (or in the distant future send these commands directly ad hoc).
