Ok. Thanks. Will watch some more videos etc to get the hang of the features.

RE: T2 Laser Strange Behaviour?
Hi Zax. Thanks. I need to read up on the trace feature then as that makes sense. Help me understand the function. Let's say I have a simple circle that is filled in that I want to trace. What is the difference between auto and manual trace, and when I click or don't click inside this circle? I don't recall seeing an option to do manual trace (I'm not in front of T2 right now)..
T2 Laser Strange Behaviour?
Hi Zax. Just finished setting up my new A3 Pro and am using the eval version of T2 laser. I've noticed a few strange things in the eval version that I am not sure if there is an issue or if I'm just a noob. Namely with editing option buttons along the top working sometimes and not others. I understand there is a limit to 1000(?) lines of G-code. I had already successfully done some sample burns so know its working. However, sometimes when clicking the trace button nothing happens, but other times on the same image it traces. Sometimes clicking the resolution button will open the popup, but other times it wont. The same happens for other buttons as well. I also tried the menu equivalent of these options and they also do the same thing. I've tried re-starting the app. Some will work, but then seemingly stop responding. I can still generate G-code, but there's an issue with consistency of function. At first I thought it was because the trace feature was still working on the image, but there is no hourglass or feature that shows progress so I can't tell if the trace is done or not. The image is small 50px x 50px and simple and had already traced at least once.
I also got a warning that the trial had expired and it closed the app (I thought the only limit was the 1000 lines of G-code?). It opened again and let me work, but the above issues still existed. I'm running Win10 on a Dell laptop. Still trying to evaluate and would like to purchase, but this inconsistent behavior is unsettling. Am I doing something wrong?
RE: Laser powers to 100% power !
I recall reading about this a while back (not sure if this forum or Google). Being an Arduino guy it's likely the Nano is driving the PWM pin connected to the laser HIGH when USB is plugged in (this is when the Nano boots). There's a hardware fix (pulling the pin LOW with a resistor) but should be a software fix (haven't used my A3 yet so not sure if I have the same issue). I would hope the sofware sets the PIN to LOW in the Setup function. If not, that's where I would look, then rebuild and flash the new firmware. This is standard Arduino stuff, just haven't dug into it to confirm my assumptions.
RE: upgraded 5.5w laser will not fire
@AntonVE. This is a common issue with any project that share different power supplies. The grounds need to be tied together. If you are only providing PWM from the A3, it won't work as there is no ground back to the A3. So connect your separate PS GND to the A3 control board GND. Do this cautiously. I presume it's low voltage.
