Gear train alignment

[bobthechemist]

Compound gear appears to get stuck on the driven gear. This issue can be avoided by adding two M3 nuts to the M3x25 bolt/compound gear shaft. The nuts are added between the gear and the motor assembly support plate (jamnut-style) and it provides sufficient space to prevent the compound gear from coming into contact with the driven gear. It may, however, present problems with the motor gear, but this hasn't been observed yet.
