Issues with Bus Servo Driver board & SCS0009

[Trymmelfink]

Building the Amazing Hand kit, I’ve reached the finger calibration step involving connecting the servos. Using the program FT SCServo debug 1.9.8.3, I can set individual IDs to the servos, but setting any rotation value makes the servo go completely haywire, making what appears to be random movements. Even when just connected, the monitored values are fluctuating heavily.

I’ve tried all connected/unconnected combinations of the jumper pins and backside pads, no difference.

“No matter, I’ll just use a xiao” I thought but that failed even more; whatever I try, I can’t even ping the servos.

Questions:

• Why does the servo go bananas when using the FT SCServo program?
• What’s the correct voltage? The product page for the amazing hand says 12V adapter, the servo spec says 6V but the enclosed adapter is 5V. I’ve tried a 6V I had as well but that made no difference.
• Does the topside jumper matter at all when going the xiao/uart route?
• What’s a minimum working program for xiao esp32c6?
• What am I doing wrong? Is the board defect or is it me?
• Is there a single Seeed product with worse documentation than the amazing hand? The level of “eh, you’ll figure it out” is breathtaking.

Is there a single Seeed product with worse documentation than the amazing hand? The level of “eh, you’ll figure it out” is breathtaking.

Hi there, yea, that about sums it up out here on the bleeding edge, expect cuts I think, but would agree in general for this such a new territory for seeed, IMO. it can ONLY get better

We can try, help each other until then

Did you see my video of the board and servos in action, maybe that will shed some light, I set each servo up first with the address, sounds like that may be part of it. Then the jumpers, it may be echoing all the commands and really driving the thing bonkers. Provide a picture please, let me see, what you got going on

Issue with Bus Servo Driver Board and Pico 2 over UART

Hi there, So I was able to perform all the tests and Work with both modes and two servos. Bottom line Everything works! USB mode = Jumper on Top & Solder Bridges on Bottom. Commands to move or init servos come from a USB host (terminal) by way of a Python script or dedicated control program. Find your com port… First step. I used a Python Script to change the ID of one of the Servos. (always power off after) I used another to verify the ID’s I used a third to Send position command…

Stay at it you will figure it out, your close.
