Useful 3D printed parts for the Exos-2
Many of the early problems I had with my Exos-2 mount and ES 102CF OTA have been related to cables getting snagged or unplugged. A snagged cable can cause the RA or DEC steppers to break phase and a loose USB connection will cause a loss of communication with the PMC-eight box. These problems cause a lot of frustration and loss of valuable astrophotography time trying to find the problem then reconnecting and re-homing. I should point out that I control my mount using CDC with my desktop computer inside my house and a 20 meter USB cable running to the telescope out in my front yard.
I have pretty much solved these problems with several 3D printed parts that I designed. A short description of each of these parts is included below along with a link to a more detailed description and a printable .stl file on thingiverse.com.
1. A tray to hold my iPhone 7 parallel to the axis of the OTA so I can get fairly close polar alignment using the iOptron Polar Scope Align Pro
2. A USB cable clamp to make sure this cable does not disconnect.
3. A 2 inch diameter snap-on leg clamp to control the stepper and/or heater cables. I include a variation of this clamp which includes a simple power distribution panel.
4. A leg clamp that firmly grips the Exos-2 leg and has a feature to slide on the PMC-eight box. This replaces the aluminum block and velcro strap that comes with the PMC-eight.
Anyway, I wanted to share these parts with all of you. If you have a 3D printer, know someone who does or want to use the 3D printing services that exist online, you can print these and hopefully avoid some of the problems that I have dealt with.
Hope this helps!
