Hi Harrison,

I tried both with and without pump board. This difference made no sense.(i.e. The same error occurred.)

I’ll ask Labmaker about this problem.

Thank you for the help!

Hi Harrison,

I firmly wiped out silver rings with alcohol and unpluged the sensor, but it didn’t work.
The same error sentences were printed.

Is there any other solution?

Thank you.

Hi Harrison,

Thank you for the reply.
>You said it worked well, but then at some point it started showing this error – is that correct?
Yes. It worked well until last Wednesday, and then every time I try to execute “bash cb.sh”, this error occurs.

I can’t know if the cause is due to one specific reactor because I have only one reactor.
However, even after wiping down the lid with alcohol, the same error happened.

Is there another possible cause?

Thank you
Tatsuya

Hi Harrison,

I took over Chi. Bio. from Nobuhiro.

I replaced app.py with newly released one, and pumps come to work well!
Thank you for updating!

However, after several experiment, I bumped into another problem.
When control board is connected with reactor and then execute “bash cb.sh” in putty terminal, it says “Failed to recover multiplexer on device M0”

Start up is successfully complete if no reactor is connected.
But I connect reactor and press “scan” in GUI, then the same error occurs.

Do you know any solutions?

Thank you.
Tatsuya
