double check your power supply.
power is good, the robot is programmed and it works perfectly. I calibrated the servos into their right position manually but they’re not milimetrically calibrated - this robot has to climb walls, that’s why I want to be able to connect the SSC-32 with lynxterm, but I’ve been having those problems.
Can you show a photo of over top of the power terminals.
very interested to see a 4dof wall walking hex… 
so let me step back a bit. you have the robot working correctly but you need to go back and re-calibrate the servos so they are 100%.
Remember you need to change the baud rate when connecting to your Pc, although it does look correct at 115.2 kbaud and DB9. humm.
can i assume you are using a microcontroller, along side the SSC.?
I am using a microcontroller alongside the SSC. And yes that’s what’s going on, the robot is working properly and I just have to go back and calibrate the servos so it is a 100%.
Baud rate is ok, and I am powering the Logic board and SSC with different batteries.
If its not a power issue then im really not sure what it is. you say its working correctly otherwise. 
so can you get the LED light up again after you apply power again… before sending data?
To me it sounds like the SSC-32 has reset, and this puts weird characters on the terminal window, as the SSC-32 crashes, but i can only see that lack of current would do this.
To prove the SSC-32 is still functional after resetting hit return to clear anything from the buffer, then type VER and return. The SSC-32 replies with SSC32-V####?
Avoid using 30gage wire that can’t carry much current.
Are you using a separate 9vdc battery for the VL terminal to isolate VS (servo voltage) from VL (logic voltage). ??
Yeah, I have both boards isolated with different batteries, I even unplugged everything and only powered the ssc-32 with only one servo. The servo moved (3 pulses) and then I lost connection bet.the SSC and the pc. When I type ver nothing happens, I cant even type ver cause the lynxterm is constantly writing “y”
im all out.
if this doesn’t result in it being concluded as a power issue then ill head my hat. [size=85]i dont have a hat[/size]… ill buy one… and ill eat it.
sorry if i go over things again or ask the same questions…
ok. so the hexapod works perfectly fine before and after connecting it all back up.
But going back and simply connecting up the SSC cause the Y read outs…
baud set to 115k?
and connected properly the first time you “calibrated” the servos?
what about connecting it up with no servos attached?
Yeah that’s all right. I tried that already, no servos connected to it. I didn’t get the Y’s, but when I typed ver, I got nothing on return
That confuses things further. 
something is not right here, as you have already figured. but im really not sure im going to be much more help to you, without pointing out anything i havent already covered.
did you follow a tutorial when you first set your robot up? if so what one?

that one, I would like to mention that we are not using the default servos, we are instead using very powerful ones and we also have 2 relay modules connected to the SSC
Bingo…
Care to share the servo spec? 
Could the conditions for the relay modules be the issue?
have you tried without the relay modules?
I believe I tried without the relay module, I am 98% sure, I can try that again though.

We got 24 of those very powerful servos, and they are all connected to the robot, they draw a bunch of current, so much that we usually use a motorcycle battery for real testing. And we burnt an SSC-32 once and had to install a fuse.
Oh and I don’t think the relay module is the issue.
ok ok, I could have only assumed the conditions were normal…
Current Drain (6.0V): 300mA/idle is pretty ok and wouldnt be an issue, if you have the appropriate battery. SO, What battery have you been using when you get the Y error?
At what Voltage??
id start again. 
So the motorcycle battery is a 6V battery, so that’s fine. It just draws a lot of current, one cable from the power terminal got caught on something, touched the other cable, and they melted together shorted and boom. Very fast.
Anyway, the problem is still the calibration thing, I havent tried connecting the SSC-32 with the computer with the motorcycle battery though
Yep ok SO, What battery have you been using when you get the Y error?
6V battery that comes with the kit

by the way, thank you for your help and the quick responses!!!
The 7950 is optimized for 7.4V LiPo batteries. The 6V 2800mAh NiMh battery could never power a 24DoF+ hex made p of these servos. Each motor draws about 300mA at no load idle and up to 4.8A at stall at 6V (higher at 7.4V). The 6V, 2800mAh battery can provide a maximum of 2.8A for short periods of time. You’ll need a 7.4V, 5Ah+ LiPo battery capable of 20C discharge or more. Try one servo connected to the SSC-32, ensure the serial to USB cable is working properly (many of them don’t) and double check the baud rate and COM port (and of course power).
Hi CBenson. Even with the motorcycle battery we are having a lot of power issues. We had to switch from a 15 AMP fuse to a 20 AMP fuse, because the 15 amp was getting fried from the amount of current flowing through it. We are evaluating the possibility of powering each side of the hex with 2 different batteries of the type you mention.
Could you give me a hint on exactly what brand of that 7.4 LiPo should I use?
Thank you
We currently don’t offer any high capacity LiPo batteries, so we don’t yet have a reliable supplier we can suggest.
That’s Ok, I am going to get two new batteries and I’ll let you know how it goes.
Thank you
