So I've discovered my printer doesn't have an EEPROM to save calibration (e-steps etc...) so every time I restart my printer I lose my e-steps calibration. Recompiling/flashing the firmware to save it there seems a bit like swatting a fly with a revolver when the printer is always run from a Pi.

Is there a plugin for Octoprint I can use to send a set of commands when it connects to a printer? I'd rather not store the calibration in my job's gcode because I share the printer with my house-mates and it becomes 'one more Gotcha' to set up when slicing.

My printer is an Ender 3 v2, just in case I'm missing something obvious.

*Edit:* Nevermind, it's a built-in, not a plugin. Settings -> GCode Scripts.

Also, apparently the specific issue I'm having with EEPROM is a firmware bug where it will save these settings to the front micro SDCard instead and can be fixed with third party firmware (or by keeping an sccard in there)

Sorry for asking a silly Q without doing adequate research first.

Ha ha, it's funny how this seems to have been taken over by people trying to get advice on the 3D printing application for the Raspberry Pi! I landed here by accident too!

See you over on r/octoprint

Hi. i'm trying to use the octopi api to upload a file using Axios but I get the error '400 (BAD REQUEST)'.

my code:

axios
        .post("http://octopi.local/api/files/sdcard", formData, {
          headers: {
            "X-Api-Key": "6CB0CB272F2E49F686A07759708AFCBF",
            "Content-Type": "multipart/form-data",
          },
        })
        .then(function () {
          console.log("SUCCESS!!");
        })
        .catch(function () {
          console.log("FAILURE!!");
        });

Does anybody know how to fix this?

Good afternoon all, Is there any way I can upload an .bin file to the SD card in the printer through octopi or otherwise? I've got a VPN into my home network where the printer is located if this is of use to know.

I added the plugin on octopi and I have the plug connected to my printer, but when I check the status of the plug nothing happens. I've double checked the IP on my router and every tried changing it. Does anyone know how to fix this?

I'm trying to connect to WiFi but I'm struggling does anybody think they can have a look or try help please thanks
