Not likely, especially if you are only using 1/255. The output isn't much more than a laser pointer and worst case you get a fraction reflected which would be diffused and less likely to cause any damage.
The typical damage from a laser diode isn't poor vision but rather a "blank" spot on the retina, over time your brain will compensate and you wouldn't even notice it unless tested or examined.
yes and no. It cant directly control a 3rd axis (there are is only an x and y on an elekspro so around would make 3). The reason is because the board can only control 2 axis motion. It can be replaced with the eleks mana 3 axis board. However if all you want is to engrave a round object you only need x or y axis motion. So if you disconnect either the x or y and plug in a rotational axis, you could engrave on a round object. There are no cheap rotary axis on the market for these machines though. Here is what I am talking about.
Notice the laser only moves in one axis and the rotary moves in the second axis. This rotary axis was 3d printed and isnt commercially available. Youtube Video
I have the 3-wire fan. Yellow gets 12V as soon as the 12V supply is switched on (button in) and runs the fan. Red wire is PWM to the laser. M3 S1000 sets full 5V to laser, M5 turns it off. Lower S numbers reduce the power level of the laser.
@LukaszL You definitely want to use bi-directional scanning, I was just pointing out that these options are useful for troubleshooting.
Once you get the machine dialed in it will run the full acceleration and bi-directional just fine, in fact my default settings aren't all that aggressive, I would say a 6 out of 10, some users turn it up to an 11 and get awesome results but to do that you need it to be mechanically perfect.
No wobble in the head or gantry due to wheels or bearings, everything square, adjusted for lowest possible friction and belts at the correct tension - then speeds up to 6000 are possible.
