I am having an issue trying to get my new DTR 3w NDB7875 aimed. I am running it at 2.3A on a flexmod, analog, 3 element, arduino uno.
I know I am still trying to get the speed down as well.
How exactly do you guys aim your lasers? What are you using, jewlers loop, black paper? Need the actual process you go through. Also I don't have a Motorized Z axis, mine is more like the emblazer so I have been using a laser cut piece of plexi to set the height of the laser.
