3D-printed R.A./DEC Motor Enclosure for CG4/EQ3 EQ Mount. The motors are 0.9° NEMA-17 with pulley ratio 15T:30T and 130-2GT belts.
I also designed and printed a hand-controller enclosure for AstroEQ V4.6 PCB from ABS plastic .
I use a ATTiny85 Arduino board and a five-position switch for mode and speed selection (long-push = cycle through ST-4 - 2x - GOTO mode, click LEFT - RIGHT - UP - DOWN = R.A.- - R.A.+ - DEC+ - DEC-). There is a red-green LED indicator to indicate the mode (green = ST-4, orange = 2x, red = GOTO). See 2:05 in the video clip below.
Hand controller , DEC motor drive, and R.A. motor drive can be seen @ 1:57, 1.28 , and 1:38 respectively in the video clip.
