Then more of the missing head angle stuff. Show stopper.

[nilsbore]

We had the same problem just now, could have been computer load that caused it.

[nilsbore]

But we haven't seen it at all for the week that we've been running the system here now...

[cdondrup]

Had the same error today in the morning...

[nilsbore]

So this is a new one then?

[nilsbore]

Might it have something to do with the magnetic strip stuff?

[bfalacerda]

I don't see how, but @cburbridge ?

[cburbridge]

Not sure, I've forwarded to christian...

[creuther]

Don't really know how the new stuff could be responsible for this, especially across several robots, but I've forwarded it to MetraLabs. Just for diagnosing: Does the CAN bus/driver eventually recover? If not, what do you need to do to get it functional again? The next time this happens, can you see whether one of the EBC ports shows an error (in the status display)? Shouldn't be the case but who knows...

[bfalacerda]

Did we figure out what's happening here?
