Would like to know if the following are compatible for pan tilt system …
To be used as an altazimuth mount
Phidgets 3329 _0 x2
Servocity Ddp155 x1
Servocity Ddt560 x1
Phidgets 1067_0 x2
What other mechanical interface parts are additional required?
Can the ddp155 operate on a 45 deg angle?
Follow up note…
Can the pt785-s be used instead with the phidgets steppers?
I think the included servos would not be accurate enough.
Thanks.

You don’t mention the weight or object you are going to support.
The DDT560 is used with R/C servo motors, not steppers.
How about posting the links for the items you want to discuss.

I want to replace servo with steppers. Those listed above. Here is stepper motor link.

Someone did a conversion of the pt785-s, but i’m looking for drop-in type solution (if possible) for altazimuth mount using steppers like those listed above. Link to mod.

The steppers have the torque. The shafts are 1/4" rather then the servo horns of the R/C servos, so I wouldn’t call it drop-in.
The R/C servos are something like 67 oz/in, so you probably don’t need 600+ oz/in.
What are you going to drive the stepper motors with?
I have used tilt/pan parts with R/C servo gear drives from Servo City before successfully.

None of the pan/tilt systems we offer (either geared or direct drive) are made for stepper motors, so you’ll need to hack / customize a setup which will likely require mechanical modifications.
