I won’t go through the instructions on how to build a 3D printer. They can be found pretty much everywhere online. What I will do is show the progress that has been made so far with my garage printer. The first thing is this is a Wolf / Gantry style 3D printer.

I made every attempt to insure that the bearing pairs were parallel to each other by using 1-2-3 blocks when mounting them.
The whole frame is within .010 of inch of being perfectly squared. This is really in the preparation work before hand. I have fairly large caliper that allows me to inspect each part after I cut it. This is what allowed for easy assembly. I have always found that the tighter tolerances that you demand of yourself the better the project will turn out. In this instance I insisted on .015 for the wooden pieces.
In the long run don’t let little setbacks wear you down. Just keep on trucking.
