Hi all,

it's been a long time since my last email,

but after all, i've restarted to works with my telescope.

It was an homemade equatorial 400/f4.5

I decided to start from 0 in order to review all the setup phases,

after update the firmware i've worked with motor tuning.

In the documentation:

http://siderealtechnology.com/ServoConfig.pdf

at page 24:

"Step 7, Run the motor at several speeds, and be sure it operates smoothly at all sp the motor at several speeds, and be sure it operates smoothly at all speeds

Step 7 the motor at several speeds, and be sure it operates smoothly at all speeds

Some questions:

1. must i use the slide 1?

2. Using slider 1 it stalls at around 75% of the range.

2. Why if i use the slide 2 (manual mode) i can reach a very high speed than the slider 1?

3. Finally, regarding errors, i cannot go under 2-300 ah high speed using slider 1,

are these acceptable values or there is something wrong?

Your help is very apreciated

Hi Gla,

The range of slider control may be more than your servos can sustain.  That is not unusual - it depends on the servo motor windings and the design voltage of the servos, as well as the settings you put into the Servo Control.

The range of slider one is much greater than slider two, so comparing the speeds of #2 vs #1 is not valid.  Slider #2 can't generally go as fast as #1, so it doesn't "go too fast" and trip the servo into blinky.

Yes you have to use slider #1, it is sensitive, but should allow you to run very slow to check the smoothness of running.
