News for version v2 and bom

Hello everyone, following new ideas and after reading many of your suggestions, this design now has three variations: the original version shown in the video and two new versions:

1. Version with a 1:5 planetary reducer only on the RA axis, while maintaining the possibility of having the Fysetc E4 inside the enclosure.
2. Version with a 1:5 planetary reducer on both the RA and DEC axes, but losing the possibility of housing the Fysetc E4 inside the enclosure.

Below are the links for the new files:

• Enclosure: For both new versions, use this file: https://makerworld.com/it/models/841759 and order from my sponsor PCBWAY
• And this is the top part (for every version):https://makerworld.com/it/models/841756
• For non-CNC builds: Use the same enclosure file but note that this will not support a counterweight shaft.
• For CNC machining in aluminum: Use the file above and also this PDF for threading the holes:

Choosing the Right Version:

1. Original v2 (from the video): Uses 2 NEMA 17 motors.
2. v2 with 1:5 planetary reducer on the RA axis: Suitable for medium setups (8–9 kg without counterweights).
3. v2 with 1:5 planetary reducers on both RA and DEC axes: Similar to an AM5 mount; this is CNC-only and includes an M12 shaft for counterweights.

Motors and Reducer Compatibility:

• Original Version: Requires two NEMA ZXS17/HBS17 motors with 5mm holes.
• New Version with one planetary reducer: Requires one reducer with a 5mm hole and one with an 8mm hole.
• New Version with two planetary reducers: Requires two reducers, both with 8mm holes.

Recommendations:

• Use Option 1 for lightweight setups with short focal lengths.
• Use Option 2 for medium setups (up to 8–9 kg).
• Use Option 3 for high precision setups (CNC version only).

Performance Improvements:

Adding two 1:5 planetary reducers improves tracking accuracy from 2 arcseconds to 0.8 arcseconds—a significant upgrade for just $30!
