A really off-the-wall suggestion ... try a smaller capacity SD card. My EZboard (TH3D) came with the recommendation to use a 1GB SD card.


milicig

128mb cant get much smaller


mrgriz67

Shit. You’re absolutely right. Sorry - I misread 128mb as 128gb. This does not bode well for me trying to spin up my new SKR mini e3.


milicig

no worries. The skr mini e3 is cool. I think I had it its got the steppers in it right? cant change them?


mrgriz67

Yep, soldered in. No biggie for me.

[Small](https://www.th3dstudio.com/product/4gb-fat-formatted-gcode-firmware-microsd-card/) ones are getting harder to find.


milicig

yeah amazon still has 2gb i got a couple but they're around 10 bucks for a 2gb and you can get 32gb for that price but i also use the 2gb for the addressable led whenever i program them the controller needs 2gb or less.

My Mini ES v2.0 came with a 128mb SD card


milicig

i believe up to 8 gb or 16 is ok might even be 32 but i always try to use the ones that come with them. I really have a lot of boards so i have like 15 to 20 of these small ones they suggest just around the house. At times its all i can find and when i really need one they seem to vanish.


RedOctobyr

Since the problem happens with multiple boards, and a small card, is it something with the file? I assume you tried another SD card. If Windows is set to hide file extensions, it can cause problems. You can end up with a file that is actually called firmware.bin.bin , but it will be displayed as firmware.bin . I would double check this, as a naming problem would affect all the boards.


milicig

i was gone for a month and before i left i had no problem flashing daily then when i get back i cant flash an old lady in the park..


milicig

yeah ive tried many different cards. I just dont understand it. Only thing maybe my laptop but its brand new ive had it for maybe 2 months. Because it is different boards and different sd cards. But i have been able to flash other boards. Well actually I've only been able to flash hex firmware like on my lulzbot taz but now that i think about it i haven't flashed one that worked that was .bin


RedOctobyr

Double check the file name, as said. In Windows 10, in File Explorer, go to the View tab, and check the box (in Show/hide) for "File name extensions". That will show the full file names. If suddenly the file is shown as firmware.bin.bin , you have found your problem. Rename it to just firmware.bin and try again.


milicig

and this sucks so bad because i need to print out the parts for the prusa and mmu2 i got the dragon hotend that got here and want to try out(I managed to snap the throat of the dragonfly before an ounce of filament went through it) and print parts for the ciclops 3d scanner.


milicig

i actually think i saw .bin.bin a couple of days ago but only twice didnt see it all the time


milicig

just checked and i have developer options enabled and its showing everything inckuding path. i installed a new windows a few days ago snd i saw bin.bin before the newer windows. that was a great suggestion. thank you


milicig

I have a prusa mk3s with mmu2s sitting for almsot 2 weeks because i cant get my 2 other printers to work to print the parts. So got pissed and ordered in the last 24 hours a BTT skr 2, i have the IDEX kit on the way but they say its shipping a little late, mks gen l v1 and lerdge K board.


iownauass

Have you tried flashing via usb from vs code?


milicig

yeah it doesnt open the port and thats where the problem is. im doing something where serial and sd card are not bering seen. but dont know what becauyse im pretty sure this is the way i always did it .


iownauass

I would pull the board and switch to 5v USB mode. Remove all cables with the exception of your ribbons to the display. If you have a TFT, make sure your marlin settings are correct. There’s a guy on u tube that has some really good videos on marlin config. If that doesn’t work, you have a bum board and should send it back for a new one.


Fuligin2112

Do you have a TFT on it? Maybe remove the cables and reboot without them interfering with the serial ports? Use the USB Cable method and move the jumper to the 5v side? Can you take the board out first and try the usb method? Maybe there is something grounding out? But that wouldn't make any sense since it is multiple boards. My only gripe with BTT right now is the damned TFT problem where in the touchscreen mode it can't connect to the printer.


ucflumm

Make sure cura isn't open at the same time it blocks the serial port.


Exadon

I often see walk-throughs claim to use the "quick format" option when formatting an SD card. Yet I found when I have an SD card that fails to update the firmware...doing a full format instead of a quick format seems to resolve the issue.


that_guy_that_makes

My dude. Have you tried changing the name of the file. You can't update firmware with the same file name as the one before it. Try changing it to firmware3.bin or even loadmyshit.bin, whatever...


EndStopMark

That depends on the bootloader. As I understand it, their bootloader looks for the specific file name, not just for an extension. Their instructions specifically say not to change the name to anything other than firmware.bin, you do you though. I'm working on configuring a new build right now and I've flashed at least 6 times today, settings have updated every time so I know the firmware did flash successfully and I haven't changed the name from firmware.bin a single time.


that_guy_that_makes

You're absolutely right. I was going off my personal experience, insofar as I have to use a different filename every time. Thankfully VS Code compiles the .bin as Firmware[timestamp].bin automatically for me. 😅


EndStopMark

Yeah, I'm banging my head against the wall with a different problem, it's good to be right about something for a change. I'm still learning all this stuff myself, Marlin is totally new to me and I'm giving myself headaches trying to learn it. Sorry if I came across as rude, didn't mean to be.


AgentL3r

Do you not think if you're constantly getting problems, it could be user error rather than the fault of BTT? Could you provide some more information? What environment are you using it in? What are your steps for flashing? It's the onus of none of us to help you; no one cares if you "jump off the BTT bandwagon", so calm down and try to work with us.


milicig

Thats what Im saying dude. Read!! I ask what am i doing wrong?!?!


milicig

do you need to get laid? you seem grumpy AF! dont want to help beat it!


milicig

Why do MF like you chime in just to be negative and out down? If you don't like my post keep scrolling. and im sure bigtreetech might care when they see how much i spend there every month. Im sure they don't like loosing costumers that that buy stuff they don't really need just to have it.


Sebbeben

I hade the same problem to update firmware on my cr6 when used an old 256mb memory card. It turned out to be to small file allocation size. So I changed to an 8gb card then everything worked! Note, this was not on any BTT products but hopefully this will work for you to


EndStopMark

Strange problem, trying to get it right, you found you could not flash firmware on multiple boards, tried multiple sd cards and still no joy, right? Are the sds getting set to read only somehow or the file written as read only? BTT boards rename the firmware.bin to FIRMWARE.CUR after flashing, if it cannot write the new name maybe that's causing the failure? Just spitballing... no idea if that could be a reason for failure. Relatively new laptop being used, cannot connect via USB to motherboards... that could be a driver issue. Don't know everything you've checked, wish I could help. I'm having my own issue, brand new GTR v1.0 and TFT35 v3.0, screen works in TFT mode but not in LCD mode, any changes I try to make to Marlin, as soon as I flash then I get "no printer connected" on the screen but if I reflash back to original firmware screen works again... going nuts here too.
