Hi Tom,
So I got the AstroEQ from you. I just configured and tested it with my Losmandy G11 S.
While I plan to install Nema23 motors in the future, currently I'm still playing with the original motors.
It has Hurst motors, 7.5degree/step, 150:1 gear box and 360:1 worm.
The problem I only hear hiss from the motor but it seems not rotating. But when I try the slewing buttons of EqMod, while it only gives a stronger hiss when the button is pressed down, I did hear it rotates when I release the button. I guess it's a backlash compensation operation.
So I think the problem is it does rotate without any load (when compensating backlash). But when there's a load it doesn't work.
I've set the current limit to maximum (clockwise to the end). The Hurst motor has a voltage rating of 12V and current rating of 300mA. I don't think current is the problem. But could voltage be? This motor has high voltage rating than most motors.
Or is it because the wiring of the motors is different? Is the RJ11 wiring a standard which most manufacturers will follow?
Regards,
Yao
