Other notes: Spoolman is also running on the rpi. No other hardware, no web cams, no adapters other than AC-to-USB.

Describe your issue:

I’ve switched from Marlin to Klipper a few weeks ago and everything has been good for the most part except I persistently get these TTC errors and I can’t figure out what the issue is.

I’ve read the article in the knowledge base but it seems like the root cause could be just about anything hardware related.

I’ve already tried replacing the USB cable with a brand new, shielded cable but it hasn’t fixed the issue. I’ve read through the logs and it looks like CPU load and memory are fine to me unless there’s something I missed.

Does anyone see anything in these logs that might explain the issue?

I’ve noticed that the AC-to-USB adaptor was only an 8 Watt adapter instead of a 12 Watt. I’ve tried replacing that and will see if that helps.

As already described in the article you linked, the (unfortunate) point is: From the log and this error message you cannot conclude to the root cause.

The points raised and collected are to our best knowledge the contributors that may lead to a TTC error.
