Hi
Seems too quiet ...
Is anyone actively using this solution?
I would love some tips on setting up an eq-3
, manly which belts/pulleys to buy, etc

So... back to my daily catharsis.
The 8825 drivers are fc&%$&/ up I guess. Changed to another driver I had lain around, some A988 compatible-ish ones...
Now it runs much smooter..

So I found the wiring diagram from the step driver and I think my connections are correct...

Connecting the motors, a little help...
The board as the following labels on the motors pins:
2B 2A 1A 1B
From the motor specs, its says that:
CoilA = BLK and GRN
CoilB = RED and BLU
Is the correct connection:
(option a)
BLK -> 2A
GRN -> 1A
Red -> 2B
BLU -> 1B
Or
(option b)
BLK -> 2A
GRN -> 2B
Red -> 1B
BLU -> 1A
Plz see photos
Im asking this because currently I have option B. So even that in slew mode both motors spin, when in track mode the tracker motor just shakes back and forward.. Any clues?

Hi All
First thanks to Tom for this project!
I will be a proud owner of a plain, brand new SW EQ3-2 Deluxe (!) mount in a couple of weeks. Without any motors, etc.
So I came across this project and decided to try it, using only spare parts I have around.
So, I have:
- mega 2650 + ramps 1.4 with 8825 drivers, probably from Aliexpress or similar
- Wantai (?) step motors, model 42BYGHW811, specs in here: http://www.wantmotor.com/product/42BYGHW_EN.html
I'm not trained in electronic so bare with me... I'm a poor sysadmin
My first question is how to setup the configure values on program, and if any hw modification is needed on the arduino/sheild.
I'm still trying to read all tutorials/faqs/etc... But it takes time to catchup
Thanks
