Hi all! I used to engrave WiFi QR codes on a D1 Pro 20W, but I’m struggling to find correct settings (power/speed/mode) for S1 40W. Feeling myself silly but could anyone please share their settings? 
Two things:
- Your 40w will burn about 75% stronger than our 20w. Has to do with dot size.
- Your dot size will be somewhat larger on the 40w. That is why #1 above.
Any shared settings would only apply to the user sharing them. You need to test on your setup so you will know what is good for you. I would increase the speed or reduce the power. For example, if your 20w power setting is 30%, try 20% on the 40w machine. Remember proportions from high school math? Thought you would never use it?
