Copy all you want. We are here to share experience.
This is what I do to ensure parallelism:
1. Stack 3 plates together and I used stapler gun to make sure it doesn't move (wood clamp would work but I don't have one:0)
2. Drill the hole for roller bearings + motor shaft using _drill stand_.
3. Remove 1 plate then drill the shaft holes.
4. Mount the plates + shaft + bearings and start fixing the u-clamp.
Whole thing (3-axis) takes less than 1 hour. |
