Here's quick video that shows basics of mirror alignment for CO2 lasers.
Keep in mind that aliment errors "compound" further down the line, meaning that small deviation on 1st mirror will have larger deviation on second and so on. If your CO2 tube is not aligned to 1st mirror, you might not be able to align your 3rd mirror at all.
