How to tighten carriage?

[NedMan (Ned Hill)]

See my post here on replacing the x-axis belt. I describe how to tighten the carriage in the post.

Start here:

The laser head carriage is held on by the 4 carriage wheels. The wheels are mounted on eccentric posts so you need to first loosen the post screws on both sides. You can then use a 2mm Allen wrench to rotate the wheels away from the rail to drop and remove the carriage. If for some reason one or more of the posts don’t want to fully rotate you would then need to retighten the post screws and then remove the screws for the wheels and take the wheels off.
