Communication timeout with Repetier Server

CR3D

Hi Guys,

I use Duet Wifi and Maestro in combination with a Repetier Server Touch Interface.

I really often have problems with an stopping extruder. When I take a look in the console I can see the communication timeout like in the picture.

What´s the problem here?

Thank you @dc42

But ist the communication timeout also a problem with the heating fault?

My main problem is the timeout...

To the heating fault

-> I have done a Auto PID tuning
-> I use a silicone sock
-> Temperature is really stable

The heating fault occurred nearly 2 hours before the communications error.

In recent firmware versions, the default behaviour when there is a heating fault is to give you a few minutes to sort it out, and if you don't then it assumes the machine is unattended and tries to shut it down.

Yes that´s right.

So whats the problem for the communication timeout?

The heating fault is a seperatly thing in my eyes...

You have some other problems. Twice there is the sequence:

es after '''S''', expected 3
Done!
Response while disconnected:

The first line is probably part of an error message from the Duet, but Repetier has chopped off the first part. I've no idea about "Done!" but I think that's from Repetier, not the Duet. After that, Repetier seems to think it shouldn't be connected and is surprised to see a response.
