High resolution Digital Setting Circles (DSC) for Dobson telescope GSO 10" and others (edit DSC-2-320T.f3d).
Use 10x Az-Gear-650T.stl.
Use rotary AB encoders and 608 bearings.
Use M4 screws for arm's axes and Alt-M8M4-Adapter into bearings.
I have used BluePill STM32 board, bluetooth module and based on the Dave Ek's files.
Why Bluepill? Because this stm32 has quadrature decoders buit-in.
Why Bluetooth? Because is low energy. Therefore is not Iphone compatible: only wifi is supported (I am working in it, an esp8266 version).
(https://eksfiles.net) to run with SkySafari in Push-To mode with 46.800 Az. steps and 23.040 Alt. steps (for 360 steps/rev. encoders).
Next update: enclosure for electronic board.
You can use PLA but use PETG for springs!.
Next version: without holes in mount for easy installation.
No brand PLA and PETG
V1.1 (12/03/2019): Schematics updated. Issue: Rx And Tx swapped in bluetooth module.
If you squeeze the shaft screw a lot, the springs may need to have a higher core due to the crushing.
Use Assembly_Test_A and Assembly_Test_B to check the correct print settings.
V1.2 (15/03/2019) Az. and Alt. springs 8mm high added.
