check out my build thread, amazon 2.3 watt in Canada.
it should give some examples of whats capable at that wattage. I’m happy with my amazon laser. let me know if you have any questions
I bought my laser from Amazon, 2.3 watt, constant current driver, which made things very simple. https://www.amazon.ca/gp/product/B07H98XHWN/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1
I just updated my machine to the latest Ramps firmware available , 414.
If you are going the RAMPS route, here are the changes in firmware I did to make it work. you wouldn’t have to modify the steps per mm.
just hook up your laser control pin to pin 44 after that and you’re good to go.
