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

I don't know if the RJ11 is a standard, all I know is skywatcher use if for there D-A kit, so I used it to for compatibility. You can check if you have a multimeter - measure the resistance between pins 2 and 5 (or 3 and 4) of the RJ11 connector of the motor, if it is low resistance, then the connections are the same.

What settings have you used in the config utility?

Do the motors move at any speed? (e.g. 1x, 2x) or is it not moving at all.

I used 7.5degree/step, 150 gear ratio and 360 worm ratio for both RA and DEC, no ustep.

I just opened the motor box and found it has 6 wires. I guess two center pins are used. I also looked at the motor wiring, probably it's different. The two wires which looks like center pins are not connected to 1 and 6 of RJ11.

I'll consider either make an adapter cable, or just go for custom NEMA23 motors. Thanks!
