I am connecting to a Moonraker API server via HTTP using the webwrite() function. This has been succesful when sending simple data such as individual Gcode commands.

The problem I am having is sending a complete .gcode file via HTTP. This is possible and is shown in the Moonraker documentation but i have not been successful ata implementing this so far.

From Moonraker API Doc (https://moonraker.readthedocs.io/en/latest/web_api/#file-upload)

POST /server/files/upload`
Content-Type: multipart/form-data
------FormBoundaryemap3PkuvKX0B3HH
Content-Disposition: form-data; name="file"; filename="myfile.gcode"
Content-Type: application/octet-stream
<binary data>

Hi,

Could you please elaborate on the response you receive and the specific MATLAB Code you are using for this?

Are you recieving an error if you send the contents of the .gcode file, or if you send "myfile.gcode" as a parameter?

请先登录，再进行评论。

Hi Will,

I understand that you are trying to send a GCODE file from MATLAB to a Moonraker API server. The Moonraker documentation snippet that you have shown indicates that a “multipart/form-data” HTTP request needs to be initiated.

Unfortunately, MATLAB's “webwrite” function does not support multipart/form-data requests, which are necessary for uploading files as described in the Moonraker API documentation. However, you can use MATLAB's HTTP interface to accomplish this task. The following resources from MathWorks should provide guidance on sending multipart form messages:
