AstroEQ Support / Re: Side Real with LV8729 driver
« on: April 01, 2021, 11:36:11 »
Received LV8729 modules this morning. Have tried replacing 8825 modules on v4.6 AstroEQ. Here's the result:

- R.A. tracking noise is almost inaudible, so does the 8825's.
- GOTO noise is also about the same as 8825's.

Setup for both 8825 & 8729: v.8.20 F/W, CG-4 GEM, Pulley ratio 30:15 (40T pulley will hit the R.A. clutch lever) with 130-GT2 belts, 1/32 microstepping, current limit 1A, 0.9-degree/step NEMA17 motors .

Conclusion : Can't tell the difference in performance between the two modules for the above setup.

Thank you : Tamas & Tom.

Interesting. Is your hex code compatible with PCBv4.6 kit?  Thanks.

Can you share the covers for the nema17 motors?

I 3D-printed hand-controller enclosure for the V4.6 PCB from ABS plastic (see 1:57 in the clip). 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 for details.

I also 3D-printed enclosure for 0.9 NEMA-17 DEC (1:28) & R.A. (1:38) motors.

I printed motor covers and PCBV4.6 enclosure from ABS-plastic, all designed by myself. STL files will be published on Thingiverse.com
