What type of laser to use

Hi
I want to add a laser to my machine to enable me to line up at odd locations. I have been searching to find something suitable but have not found anything.
What does the plasma Gurus use?

I found some line lasers from a Hobby Shop over here. Small 12mm tube like modules. I am going to put them in a 3D printed housing of sorts and see how it works.

I used something like this www.aliexpress.com/item/1005005497606307.html

As I had 24V on the gantry, I used a small 24v to 5v converter to power it

Hi,
I did not use a cross laser but two Line Lasers, which cost me 4 Euro a Piece from amazon. Mounted them via a 3d Printed part to form a cross which is always perfectly centered no matter which hight the z axis is i found it easier than to align a cross laser module since it is height independent no matter the position of the z axis or material thickness .

regards
