Linear bearings

The Y-axis runs on a linear bearing. Here's a video on cleaning them:

If there is a rust build-up (oxidation), you can buff it out with Scotch Brite.

It was recommended to not use grease, because it can collect dust.

Calibrating Mirrors

This is often a slow and tedious process. When calibrating the mirrors, do in this order:

  • Mirror closest to the laser
  • Y-Axis mirror
  • X-Axis mirror

To determine if the mirror is aligned, add a piece of tape to the front of a piece of paper to easily tell where the beam it hitting.

NOTE: There might be a better way of doing this, but since it's a repeated process, we wanted something we could easily throw away to re-test with fresh materials.
