Another option are second hand RPIs. Where I live, there’re plenty of 3B/3B+ in good condition at reasonable prices ( 40-50 euro). I got one for my Voron and probably I’ll get another for running Octoprint on my MK3S+.

Or the Orange Pi 5 is available fairly reasonable. I hear it runs Octoprint very well.

If you already have a Pi with Octoprint and can't get another one for a reasonable price now you can always put another Octoprint instance on the first Pi. Chris Riley has several how-tos for this.

The hardware choice and design is 100% dumb.

Unfortunately, I read somewhere that they spent a bunch of software resources to fully rewrite the ESP firmware. That pretty much means they have invested so much ego into both the hardware and software design, that they will never admit it's a dumb design and change it.

"10.43mb file sent in 74 seconds" So the 40+meg file I just uploaded to by MK3/OctoPrint in a few seconds would take 5 minutes, WOW!! In my eyes that makes the new "Ethernet and Wi-fi connection" and most likely the "Prusa Connect" useless.

With that news I am rethinking my Mk4 order!
If I do keep it, I will have to plan on putting OctoPrint on the MK4 as well and just disable Prusa's WiFi.

So here is Wifi off of my AC6-Pro

10.43mb file sent in 74 seconds

140.94k/sec

Channel1 (2.4 GHz, 20 MHz)

Signal-40 dBm

AP/Client Signal Balance Good

Standard WiFi 4

MIMO Configuration 1x1

Rx Rate 43.3 Mbps

Tx Rate 58.5 Mbps

Even though 43Mbps is slow as shit, its like 5mb/sec, but if we are maxing out the serial on an ESP at ~150k then hello octoprint. What were they thinking?

Could someone retest wifi and wired ethernet with new firmware?

"Developers have optimized file transfers between Prusa Connect and the printer resulting in higher transfer speed."

Unfortunately the ESP8266 even if it is fast if used on its internal memory, uses serial port to communicate (what it receives or must send on WiFi) with the ST Mini or MK4 board, and the reliable serial speed allows a network speed around ~100KB/s MAX.

I have a look at the schematic of the Mini and it has several STM dedicated line connected directly to the Ethernet chip, and it doesn't use any serial pin internally; so it must be fast.

I assume for the Mk4 it's the same as the XL and Mini, so yes, Prusalink requires a USB stick to be inserted.

So where is the file saved upon transfer - do you need to have a USB drive inserted so the file can be saved there? In essence its a transfer from computer to USB drive connected to printer?

This right here! Use hard-wired ethernet if at all possible. you don't want your wifi-router getting rebooted by your isp for firmware update while you've got a multi-day print going...
Prusa printers are not affected by that. They never print over LAN or over cloud. g-code file is fully uploaded to the printer (over LAN or over cloud) and only then print starts.
