General Discussion / Re: What can AstroEQ do for me?
« on: May 15, 2021, 02:35:51 »

My mount is a budget CG4/EQ3-2 with AstroEQ v4.6 controller. This info may answer some of your questions.

Does it sit BETWEEN the mount and a computer?
- Yes, you'll need a USB cable to connect to a PC. In my case, it is connected to a wireless computer (ZWO ASIair Pro) via a USB cable. The controller is connected to R.A./DEC motors via phone cables.

IS it a stand alone unit that attaches to the mount?
- It is not a stand-alone GOTO controller. You'll need a PC connection for that. However, with a key pad, it can function as a stand-alone hand controller.

Does it go INSDE the mount after removing the old controller board?
- I don't think you can replace existing controller board without modification. AstroEQ box is normally attached to the mount, OUTSIDE. It has R.A./DEC ports that can control respective axes via phone cables.

Does it have a port for a guidescope ... can I use software to control a guidescope to guide my mount?
I found mention of ST4 port in FAQ but does it even NEED this?? what is EQMOD and does the board have this built in?
Will it allow use of guide camera?
- Yes it has an ST4 port that connects to camera's ST4 port. Star guiding is done via software like PHD2.
In my case, I don't use ST4 guiding/cabling. Instead, star guiding is via ZWO ASIair Pro.

Hope it helps. :)

All connection ports are listed in AstroEQ Arduino Mega schematic here https://www.astroeq.co.uk/doku/lib/exe/fetch.php?media=astroeq-arduino-schematic.pdf.

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
