Hi,
were they for control with astronomy software with ascom drivers to slew and track? if so which driver did you use in the software and how did you translate outputs from the software to inputs that the stepper controller would understand and use?
the controllers from jaycar, ocean controls and several others have built in serial interface hardware and software that comes with it that can be used to drive the stepper. but the challenge would be to use that interface with astronomy software commands, especially for autoguiding.
I guess its similar to DIY CNC machines where they get standard CNC 3 axis controllers and serial interface it to the software Mach3 which works with different hardware.
