« on: September 22, 2023, 10:13:19 »

Hello everyone!!
someone has a schematic for using driver TB6600 instead of DVR8825? I'm making my own DIY board.

Thank you in advance

Hi Tom,
I checked the solder joints and the jumper, and it seems to be ok.
I tried to replace the 8825 but nothing change.
I made 2 Astroeq and both have the same problem.

What do you think about?

Thank you a LOT

AstroEQ Support / Sideral Tracking

« on: March 31, 2021, 14:47:08 »

Hello!
I built my own version of Astroeq with ATMEGA162.
GoTo seems to work correctly RA and DEC and it moves quite precisely to the selected objects, but the RA sideral tracking is about twice faster.
I'm using a LX70 mount (the same as EQ5) with NEMA17 stepper motor 1.8°
AR gear is 26T to 48T
DEC gear is 24T to 48T
RA Worm is 144

There's something wrong with the calculation?
Thanks
