I'm testing this version 2.05RC2
Now uptime 47:00:29 ago
I finished 2 long time prints and Used output buffers: 9 of 24 (24 max)
IMHO after 4 long time prints, buffers come closer to max and printer freeze... again =(

Why does DWC 2.0.4 dimming the screen brightness and do not press anything until you reload the entire page?

@dc42 said in RepRapFirmware 2.04RC4 released:

@Adrian52, thanks for your report. Looks like output buffers are still being lost somewhere. I will look into it.

Hello!
I want to write about buffer overflow problems.
I looked at the code of the program OutputMemory.cpp
I saw that each buffer has a time of its creation whenQueued.
And there is a GetAge function to see the age of a busy buffer.
You must make the M122 command show Used output buffers and show GetAge age for each buffer.
Maybe then it will become clear in which cases these buffers accumulate and how to fix it

@boldnuts Somtimes it happens in one day many times! And sometime nothing happins for a week ! This is some random bug.

@dc42 i'm use gcode generated from Kisslicer 1.5 and upload it to printer with browser Google Chrome without any plugins.
Now i have 2 printers with Duet.

First printer with Duet 0.6 working stable without any bugs and problems.
RepRapFirmware for Duet version 1.19 running on Duet 0.6
Used output buffers: 2 of 32 (32 max)

Second printer with Duet wifi
RepRapFirmware for Duet 2 WiFi/Ethernet version 2.04RC3 running on Duet WiFi 1.02 or later
Used output buffers: 5 of 24 (20 max)
There memory leak and used buffers increases and increases and later printer lost connection.

I think need remember what changes have occurred with the firmware in the functions of working with buffers? if you compare versions 1.19 and 2.04 ?

@dc42 no, i have one computer and one ip address

@mat100 Automatic reset (reboot) printer ?

@dc42 Problem with overflow buffers in longer prints is still there.
Used output buffers: 24 of 24 (24 max)
And connection with printer loss and freeze.
We really need you to fix this problem, because I plan to build 2 more printers with a Duet controller. They need to work stably 24 hours 7 days a week. And when the connection is lost and there are a lot of printers, it causes inconvenience and loss of working time.
And I can’t refuse use Duet controller because it is the best in the whole world!

@mat100 i'm using latest firmware and problem is still there =(
@dc42 hey ! help plz ! we need very-very to fix this problem. Longer prints now is a big problem with freeze printer =(
