How to modify Futaba's new brushless servos?

[bridlewood]

I just bought a couple of these new brushless servos and want to use them for a robotics project where I need smooth motion. The servo seems rather jerky at times when running off a computer that generates the signal pulses, so I would like to try disabling the pot and using it like a speed controlled brushless motor.

Does anyone have any ideas how to remove the circuit board? There are several "through-hole" solder joints that looks to be the motor on the left and some type of sensors on the right. Perhaps using a desoldering braid on each of those points would help free it?

My God ! :eek:


did the idea That your PC signals could be " not so good " ever came to your mind ???

just think the servos do exactly what you ask them ... :D

Yours to give them nice commands ... :rolleyes:

Yes, you could be right. I am using my own written software with simple timing code and "time critical threading", but maybe I should check it with an oscilloscope. I think the timing is right, because the servo stays in one place when it comes to rest, but when moving it has it's own logic to decide how to accelerate or decelerate the motor. Sometimes it accelerates too fast and goes past the desired point and then reverses back. This is not good for my application. I would prefer to have complete control over the motor by replacing the pot with resistors.
