***** Some servos appear to have disabled theirselves when entering in a new form *****

—> Using an USB to Serial adaptor
Each time you enter in a new module, SEQ is asking the SSC-32 card the ‘current’ servos position stored on card (to make sure the card is on, and to grab 'real positions just in case SEQ was closed but not the SSC-32, so opening again SEQ, it will be aware of the ‘Real’ positions)
But…some USB to Serial cable are a bit slow to answer within the pre-defined Timeouts, so it could loose some data and think some servos are off.
FIX :

  • go to the 'Timeouts" form (SEQ V1.02 manual page 12)
  • increase the ‘Read interval’ value to 25 or more (default is 10 ms)

—> Using a Wiport
same as above but use a bigger value for ‘read interval’, try 100 or more

—> Using a Serial cable, an USB to Serial adaptor or a Wiport
It could be a power supply issue
FIX :

  • try to separate VS and VL, using a 9V battery for VL (check connections too), and a Wall pack for VS (6.0vdc 2.0amp). More current is ok, make sure it’s regulated.

Hi,

Since this thread is called SEQ Troubleshooting I wanted to post a question about the advanced play section. I’ve noticed that there is a significant delay from when I click a button (ex. Start) to the servos starts to move. The delay is for about 4 second! Is that normal?

I can see that SEQ is running through the whole sequences one time before the advanced play section starts to send commands to SSC32. The sequences I have configured to the “Start” button consists only of step 1 to 8 of a sequence of total 48 steps.

Has anyone noticed this delay?

I’ve noticed the same slow reaction.

could you export this project with the project form and send the exported csv file to [email protected], i will test here…
is it only in ADV play form ? np on the play form with the same project ?

thanks

Hi,

I’ll do that when I come home from work today!

Hi,

I’ve sent you the files now! It is only in the ADV play form, not in the SEQ play form (where you can play one sequence or the whole project).

Um,

Nothing in my email box yet ?

Hmm,

My computer (outlook) says its ok…
I’ve sent it again, also a version with just a packed .rar file. Hopefully you got it?? (also sent you a PM about this mailing part, I don’t think we should use this thread for mailing problems :wink: )

Hey I am SEQ user and having a little trouble with it till yesterday. But yesterday I read your post and try to solve it and you know what my problem had been resolved. Actually I had done a mistake in its settings which I made correct. If you know something more about Wiport than try to share with me over here.
