No more than 4 motors run at once
So, no matter how we try to control 5 or more motors at once, none of them work. For example, if we just run drive code (for a total of 4 motors) it works perfectly fine, no problems. However, if we try to add in code for a mechanism that requires a single motor (going up to 5) neither that mechanism or any of the drive motors run. We have tried this with 5 single motors at a time, 4 in drive and 1 stand alone, or even a 4 motor system and a 2 motor system.
A second problem is in our basic drive code. Our drive system is mechanum, and it works fine, for the most part. We can drive forward, backward, left, right, and we can rotate left. However, once we get past about .23 power for rotating right in the Holonomic Drive (Cartesian), it causes all 4 motors to stop working. To fix it, we need to redeploy the code. Thanks for the help! ~Team 3408 Software Team

Re: No more than 4 motors run at once
The standard question is:
Are the three DSC power lights all bright green?

Re: No more than 4 motors run at once
Was your DB-37 ribbon cable one of the bad one's?
Did you have to re-do it? Do you have an older round cable DB-37 you could swap in? Any Diagnostic messages on the Driver Station?

Re: No more than 4 motors run at once
We bought a new cable (the one that came was assembled wrong, we tried to fix it, and broke it). So I have to imagine that one works. Also, I do have an older cable I could try swapping in, I will do that. There are quite a few diagnostic messages, but we are being kicked out right now (our supervisor wants to go home
 . ) I will post them first thing tomorrow.

Re: No more than 4 motors run at once
Have you powered the Digital Sidecar with a 20 amps breaker from the PDB? If so, your team light should be working; does it?

Re: No more than 4 motors run at once
So, we tried a different cable, there are no error messages on the DS, and also we have powered the digital sidecar with a 20 amp breaker. What do you mean by the "Team light?" If you mean the RSL, it is not working
.

Re: No more than 4 motors run at once
Double-check that the 12 volt power is actually getting to the Digital Sidecar. Your symptoms point to that being the problem.
Except that you said all three power LEDs are lit. Please confirm that you're talking about the BAT, 5V, and 6V LEDs on the Digital Sidecar.
