Please, improve the network transfer speed of the mk4 in a future firmware update.
7 minutes to transfer 20 MB on a gigabit cabled network (not even wireless) toward the mk4...that reminds me of my old 110 bauds TSR80 modem...
I have to attend the machine to load filament, remove prints and prepare the build sheet for the next print - I see no point in adding extra hassle by going to another machine to upload a file when it can be in my pocket ready for a manual transfer that takes only another two seconds.
Way back I installed a Pi on my Mk3 and ran Octoprint - after couple of days and a couple of videos I uninstalled it and found a better use for the Pi.
When my XL arrives I probably won't bother with network connection - I can't think of any use for it.
Cheerio,

With the final firmware 5.0, the upload of 44 MB takes 5 minutes. I think with Lan it should be similarly fast. Not blazing fast but ok.
If with version 5.1 the Octoprint integration is better I will not need wifi on the MK4 anyway. Although Prusa Connect is not so bad. If a USB camera would be supported I might use it permanently.

That is absurdly slow. Why is everyone making excuses for this??
RE: +1 vote for improving lan transfer speed...
It's slow, you're right. Better? 😉
Seriously, as it is now, I don't care. I sliced something, sent it to print and at some point it's finished. I walk away and continue working. I don't wait for the printer to start.
Faster would be better, yes.
Can I change it, no.
Do I want to be angry about it, no.
Can you ask yourself why it is so slow in 2023, yes
I normally use octoprint, so it doesn't affect me as much.But that shouldn't be an excuse for Prusa. This could have been solved better.But it is what it is.

I believe the lan speed is limited by the internal hardware. The Wi-Fi is definitively connected via old-school 90’s UART. Ethernet, I’m not so sure, but with 4.7 firmware I was seeing ~2Mbps, which is worse than “shitty drivers” alone could account for. Maybe they have SPI or I2C to the USB stick, which would make me sad. But bit-banging the thumb drive could explain the lack of USB hub support on the thumb drive port.
When someone asks you if you're a god, you say, "YES!"

Isn't it the case that the connection between the board and the display is the crux of the matter?
At least I think I read it somewhere. But I don't know anything about it. Sometimes they overdo it by keeping it simple 🙄
RE: +1 vote for improving lan transfer speed...
It's more than a little ridiculous that a $1200 printer with network connectivity also has the worst network connectivity of any networked appliance I've ever seen. Absolute bottom tier functionality on a feature that works fine on printers that are third of the cost.
RE: +1 vote for improving lan transfer speed...
Ok now that I've got my two MK3S's upgrade to MK4, I definitely see what you guys are saying about the wifi speed lol. It's not the end of the world, but it is a bit slow. It's not bad enough that I want to run patch cables and hard-wire the things though.

Use USB again. The fastest 😡
RE: +1 vote for improving lan transfer speed...
Well i thing is not a very good idea on the long run. I dont want to plug and unplug a usb on the printer. It may or may not at some point create a problem on the port.On my mk3s i added a wifi sd card which i get the impression that was faster than the 4000E XL wifi. Im not sure though that it can be easily fixed on a firmware level. I mean if it could be coded to run faster why leave it so slow.

Point taken!
RE: +1 vote for improving lan transfer speed...
I use Octoprint, which is fairly quick to get files from the slicer to the printer. Right now, the Prusa solutions are very primative.

I buy an fast usb drive and now i have no problems with lan...
RE: +1 vote for improving lan transfer speed...
the fact of running printer firmware checking for inputs checking for errors is hard enough for the board then you go chuck prusalink system which is also consistently checking for stuff is just too much for it the more features and more updates the slower its going to get I can almost guarantee it. there is no way without cutting features that I can see to make it faster it won't surprise me if prusa cut it in there next printer or have an additional board to run it. Its the truth technology hasn't got that far for a cheaper motherboard yet I know people will disagree with me but I can almost be certain of it it's the sad truth
Please help me out by downloading a model it's free and easy but really helps me out https://www.printables.com/@Hello_474427/models

Can you explain what you bought and how you have to configurate that?
RE: +1 vote for improving lan transfer speed...
Not to be the bearer of bad news, but the ESP32 module used for WiFi has a maximum speed of 5Mbps for it's serial connections that are used to talk to the processor on the xBuddy board. This will forever limit the upload speed to 512KB/s (give or take) over WiFi. The serial interface used on the STM32 has a max of 10Mbps, so even a different wireless module would only get you to 1MB/s.
This is a hardware limitation due to design choices. Not great, but engineering is an exercise in trade offs. If you want to go faster, plug a cable in, then you are using the STM32s built in ethernet interface.
Is it really that big a deal though? The size of a gcode file scales with print time. While I'm sure it's possible to generate a huge gcode file that prints in a relatively short time, that is what would be called a "degenerate case". The print I have running right now has 65MB of gcode, and it took a few minutes to upload. It's a 15+ hour print. Shaving two minutes off the print time with a faster WiFi upload wouldn't really make any difference.

Where did you see an ESP32 module on the MK4? The module used is an ESP-01, which is an ESP8266, which has lower specs than an ESP32. Here is a comparison between the two ESP types.

That was an (incorrect) assumption on my part, but the ESP8266 has a max serial speed of 4.5Mbps, so its not that much worse... 😆
