Print quality

bierent

Hello guys,

I recently designed and built myself a new printer mostly based on the Ratrig.
Getting it running was pretty easy but getting it tuned isn't as easy as I hoped. The printer is designed to run faster and print more accurately and uses a duet2wifi.

On straight parts it is getting pretty good although I get some lines in the layer height that i cant quite explain. Maybe I am getting too precise with that. But looking at corners I have quite some bad print qualities. I posted some pictures below and my config code to make it more clearly because it is hard too explain but the pictures show it nicely. (all printed with 0.6mm nozzle, 0.2 layer height, 100mm/s print speed, wall speed 60mm/s). I just added a acceleratometer too look at vibrations, dont seem too bad with the naked eye but it is possible of course. But I just see those sensors weren't supported at 3.2 so tomorrow I will update my duet. Furthermore my webconsole is giving more problems lately. Suddenly it got problems with wifi signal, M122 gives low dbm of like 70 but like 2 weeks before it worked just fine. I just placed an extra range extender and now the dbm is like 54 so a lot better but still the web console is slow often and uploading files it gets often stuck on the 100% for like a minute. Connecting is a bit better though now.

So my most important question to you guys:
Do you have tips on what part I need to work to print more nicely?

it gets often stuck on the 100% for like a minute.

Please update your firmware to 3.4.1 and see if there is an improvement.

I have just updated to 3.4.1 however my connection issues continue. It also happens with just browsing the webcontrol. Like sending codes in the console can have a delay of like 10 seconds. Also simple G0 commands. Furhtermore the connection falls away often. Sometimes the Duet needs like a minute to reconnect to a wifi after startup. However the dbm seems fine. Just randomly webcontrol also has to reconnect. Next to updating the firmware I also just update the wifi and webcontrol.

I did try to add an antena like explained here link text
but that didn't help.

So you've modified the wifi module to add an antenna?

bierent

@phaedrux
Yes, I tried it to get better wifi. Before it was also bad.
The board today with the new firmware also gives this popup when it's first connected.

Failed to connect to 192.168.2.164
Unexpected token '<', "

Phaedrux

Where do you see that message?

bierent

@phaedrux
On the bottom when starting up, although it does disappear quickly.

Maybe I better make a new topic with the right topic name.

Not a bad idea.

I would also try refreshing your firmware and DWC files by uploading the full 3.4.1 zip file again.
