CR10 V2 + octoprint initialize SD Card problem

What is the problem? (26.7 KB)

Hi everyone, i fiished my octoprint setup, everything works well apart from "upload to SD card" and also print from. When i drag and drop my files it says "sd card not initialized" even if i did it (sd card icon > initialize). M21 command doesn't seem to output any error, M20 shows the files on my printer.

My CR10 V2 is running the stock firmware, might be the problem ? Thanks ! :slight_smile:

What did you already try to solve it?

  • reboot
  • reboot in safemode
  • remove and plug back everything
  • search on GG and here

Have you tried running in safe mode?


Did running in safe mode solve the problem?


Systeminfo Bundle

You can download this in OctoPrint's System Information dialog ... no bundle, no support!)

terminal output

Not much errors when pressing initialize, doesn't seem to do much

  • M21 :
    Send: M21
    Recv: echo:TF card ok

I can see my files stored on my printer's SD card

Hello @Ghostcatcher64 !

Have you enabled SD-Card support in the OctoPrint settings?

But be aware that transfering gcode files to the printer's SD card can take some time and you don't have all the features of OctoPrint while printing from the printer's SD card.

Hi, yes it's enabled. And yup i'm aware i'll not be able to control everything but that's not a problem at all, start a print, monitor the print and cancel + shutdown. That's all i need :slight_smile:. I just want something reliable so SD card seems to be the best option

This doesn't say SD card ok as OctoPrint is expecting. I think I have seen a single file plugin that will rewrite TF => SD around on the forums, I will have a search. If not, I will create one

That didn't take long - here it is:

Heyyy you rock, so it was this plugin ! I posted reddit and FB posts asking if it might be the TF and not SD card pb on the firmware, but when i looked at the "affected printers" the CR10 wasn't listed.

Will try that whenever i can, thanks a lot !

I wont be able to test that today unfortunately, now when the printer is connected to Octoprint i get a maxtemp error, i'll tell you when i've fixed that issue. I guess firmware update is absolutely necessary, gotta find which one to get !

Fingers crossed i can check your fix tomorrow afternoon, pretty sure it'll work :slight_smile:
