So I am seeing how fair I can get in the assembly without any rails.
So I started on the x-carriage assembly, and already I ran into an issue. One of the v-wheels has a bad bearing, so if it is attached it will not spin freely. You can feel something grinding inside the bearing when you hold the two inner races between your fingers and try and spin the wheel. I’m guessing this is probably a defective bearing.
Maybe a few spare parts should be included in the kit to deal with issues like this.
