The biggest thing you will be asked is what software you are using. The most common are T2 laser and lightburn. Also you can check out my youtube channel for some tutorials on starting with T2 laser.

I've just used black paint. same speeds as you are using.

double print issues are called backlash. You can fix it by making adjustments to your x axis. Adjust belt tension and wheel tension. The belts may need to be tighter or looser. The wheels should roll smoothly. If you raise one end of the machine with it off it should slide to the other side. If it doesnt the wheels are too close to the rail and binding.

uhhh how old? So on the old L7 boards there was a jumper under the nano you needed to move. which board do you have? can you post a picture?

yup painted first. just regular painters tape. I think I used the brown rather than the blue though.

reduce the max power. so if you are using 0-1000 power try 0-500. This will mean that 50% is half of half power or 25% This will give you more bands of grey.
