Hi Tom.
Yes I used that schematic.
I downloaded the github repository, used the Utility to load the firmware, used the config utility to load the EQ6 file. Tested connectivity to Eqascom.
It connected to the mount, gave a home position and seems OK. However it will not park, just sits there parking, will not slew or track. As I said I get a pulse to the steppers when I connect to eqascom. Thereafter no response from the steppers.
Does the firmware depend on feedback from the driver board/steppers in order to update it's position etc?
Thanks for the help and great project. Have ordered a board/chips and cables to build the official version, it's good to learn the system until that arrives as I have all the Mega bits to hand.
