SD Cards
What is your experience using SD Cards? Are there some that work better than others in the MK3S Printers.? The one that came with the printer works great, but my SanDisk 16GB Ultra's only seem to work now and then. Larger than 16GB unable to get them to work at all.
RE: SD Cards
After SD cards get larger than 16GB the filesystem changes. The firmware on the Prusa only understands the filesystem for the 16GB and under cards. As to your SanDisk only working occasionally, I don't have a good answer. I've heard of the SD card slot getting worn out (the thin metal shield starts to bow out and not press the card against the pins appropriately, or lets the card get inserted too far).
If the socket is starting to get worn out, you might want to try a flat-ribbon based SD slot extender like this https://www.adafruit.com/product/3687 to keep from continually inserting and removing from the machine's SD slot.

RE: SD Cards
My mistake. The threshold between the FAT16/32 filesystems and exFAT is 32GB. Larger than 32GB is exFAT and not fully supported in the Arduino world (Marlin is compilable in Arduino). I've only found one library for Arduino that claims to have exFAT support, but it is currently in early beta and the sdFAT portion of it takes up a lot of program space on AVR processors. https://github.com/greiman/SdFat-beta

RE: SD Cards
I use both 16 and 32 g cards with no issues.
The 32g card takes a bit longer when sorting files, but otherwise works fine.
RE: SD Cards
I am using a Toshiba FlashAir (W-04) 64GB partitioned into 32GB. The 64GB was less expensive than the 32GB on Amazon.ca. Go figure.
Now no need to remove SD from printer so no more wear and tear. Also like the fact that my gcode can be sent remotely from my workstation that is upstairs from the printer.
If you decide to go this route, I can provide you with the script (took me some time to figure out) that allows the card to be recognized on your network. Now works flawlessly.

Thanks!

I like that idea, please send the info you have to set it up.
RE: SD Cards
Will do once I get home this afternoon.
RE: SD Cards
Actually I found it on my OneDrive folder.
Here is the script of the config file that is found in a hidden folder on the SD Card. The folder name is SD_WLAN
Cut and paste this script into the CONFIG file and save.
My comments for what needs to be changed are next to the code lines.
[WLANSD]
ID=FLASHAIR
DHCP_Enabled=NO
IP_Address=192.168.1.103 (Choose an available IP Address on your network as DHCP is turned off for this card))

This should work for you. My friend followed the same instructions and it worked right out of the gate.
Glad to help. Took some tweaking because the documentation from Toshiba was less than stellar.
Let me know if this works out for you.

@barry-d3
Thank you for the tip and the script. I think i will try this 👍
How stable is the wifi connection?

@karl-herbert
It should be solid. I have not had any issue loading the files onto the card. With Windows 10, you have to map a network drive. Sometimes it does not see the drive and you have to manually enter the coordinates using a variant of the "map network drive option". Let me know if you encounter this Windows bug.
RE: SD Cards
@barry-d3
thanks for the feedback. I'm working with Ubuntu 18.04 and one W7 system; will try it.

Thank you for this! Only changes/differences:
Added a line with UPLOAD=1 before the UPDIR line
Copied the CID value from the original CONFIG file that was on the card because I did not see it on the back of my SD Card.
RE: SD Cards
FWIW: I have had good luck with larger (32, 64GB) cards when formatted using the SD Association Formatter. I run it on Mac, but it's available for Windows as well. I have noticed a speed difference with Octoprint responsiveness with slower cards, so use Class 10 or faster. These days, quality Samsung and Sandisk cards are quite cheap.

@barry-d3
It might be that you can tell your router to reserve an IP address for the WiFi-SD card. Windows will have an easier time reconnecting to it.
RE: SD Cards
Guys, my W-04 was working fine for a few months in STA mode. Then it started going downhill with intermittent periods when it was not working. Now is one of those periods. It seems to be connecting to my local network. As you can see in the screenshot, the bonjour service gets advertised (still with the name of my old printer).
When I ping I get this (I use DHCP which clearly gets resolver to its IP address):
When I try to connect I get this:
Does this give you any tips as to what the problem might be?
Thanks in advance!
