I set the FLUX out in the garage last night and did some engraving. Eventually I’ll try running it next to a painting hood or a solder fume extractor, but for now I can just set it on my tablesaw.
I had to restart the job 8 or 10 times because of the overly sensitive safety interlock, so I’ll have to experiment with the aluminum foil hack next. A note to the creators, can you make this sensitivity a time delayed trigger? i.e. instead of making that part of the code an indiscriminate if or when that flips a hard switch when it detects an open circuit, make it a while with a pause at the beginning of a 1/4 second or something like that. That way it would smooth out the hiccups and only indicate when there’s an actual problem. Is there an accelerometer in the laser module? Maybe use that to determine if the train runs off the rails instead of an electrical interlock.
The engraving looks good, overall. I can tell that I’ve got some tweaking to do with the power and speed, but that’s a given, and it will change with every material. My plan is to create a gradient pattern that’s about the size of a postage stamp to use as a test piece. Then I’ll be able to adjust the speed and power to achieve the best spread on each material. Hopefully I can do that with a pattern that doesn’t take a lot of time to do
