Makes sense, Wi-Fi Maestro with u.fl. and TMC2209 would be nice once the Duet 3 dust settles

What transfer speed do you get when uploading .gcode files using the web interface to your ethernet duet?
I am getting about 200KiB/s with a wifi interface.
That's low. With a strong signal, 800kbits/sec is typical for both the WiFi and Ethernet versions. It's affected by both the WiFi signal strength and the SD card.
To see whether the SD card or the network connection is the limiting factor, you can use M122 P104 to test the speed of writing to the SD card, see https://duet3d.dozuki.com/Wiki/Gcode#Section_M122_Diagnose. I get around 2.5Mbytes/sec for files between 10Mb and 40Mb.

Yes, we're looking at the TMC2209 as well.

ouch.. mine was around 0.6Mbytes/sec, my second on was the same.
Had another one around for use in a pi3, putting that into the duet got me to around 2.5Mbytes/sec too.
Another issue fixed ... Time to buy another SD card for my pi3 then. -

I tried the M122 P104 command and it gives me 2.28Mbytes/sec. I presume that the same as 2.28KiB/s which is roughly x10 times faster than the transfer rate I get through the web UI.
I tried once to move the printer, computer and router next to each other but no significant change in speed. I wouldn't mind to wait a little bit for upload but with large files Slic3r timeouts which requires me to do a more manual transfer.

Unless someone made a typo with bytes/bits vs B/b 2.28KiB/s is 1/1024th of 2.28Mbytes/sec.
Kibibytes (KiB) Megabytes (MB) 2^10 bytes 10^6 bytes 1,024 bytes 1,000,000 bytes 1,024 × 8 bits 1,000,000 × 8 bits 8,192 bits 8,000,000 bits
(from https://www.gbmb.org/kib-to-mb)
I.e the i in KiB indicates its a "binary kilo" as opposed to an SI kilo, the B indicates bytes. A lower case b would indicate bits which would add a factor of 8

Good catch. I meant SD writes 2.28Mbytes/sec which is about 2.28MiB/s which is about X10 of the 200KiB/s which I get from Web UI upload.

Just got the Maestro online to try myself, around 2MB/s for the SD card (not the fastest card). Unless the Maestro is expected to be slower due to lower specs then I can't say it adds up, being on a wired connection and the computer should be able to saturate the card speed.
Anyways, moot point for me, its plenty fast for the small prints I do.
-
The SD card write speed on the Maestro may be a little slower because the SD card interface runs at 15Mbytes/sec vs. 20Mbytes/sec on the WiFi/Ethernet. Also the SD card supplied with the Maestro may have a lower specification.

Good to know!
