Recv: echo:busy: processing

I just started printing again after a 6-week layoff. I upgraded CuraLE to 3.2.32 (and cleared the cache) and flashed the firmware ( in my TAZ 6.

With OctoPrint 1.3.10 (running on a Raspberry Pi 3 with OctoPI 0.14) I’m getting:

Recv: echo:busy: processing
Printer seems to support the busy protocol, will adjust timeouts and set busy interval accordingly

and then a lot of:

Recv: echo:busy: processing

I’ve been told this is coming from the firmware. I believe the last firmware I used was and I don’t remember those messages (but at my age, I seem to forget a lot).

These messages appear to be harmless (i.e. the printer continues to print) but they are kinda annoying. Can anything be done?

In OctoPrint, you can set a terminal filter to suppress these messages. They still go into the serial log but the terminal window doesn’t show them.
