Octoprint not loading on Prusa mini

[Herman_Hock]

I have installed latest Octorprint on SDcard on PaspberryP1 3 B+ connected to Prusa Mini+

I can access http://192.168.0.37/#control and even see my webcam.

But Octoprint does not load on the Prusa mini screen. Also when using Prusas Slicer and sending file to print I get error : http://192.168.0.37/api/files/local (192.168.0.37) ERROR

Would be most grateful for any help in solving this.

Octoprint does not load on the Prusa mini screen.

Is that a feature of the Prusa mini?

Just error doesn't tell us much - but check out this post in case you have bgcode enabled

[Information] Regarding the the new bgcode file format in Prusa Slicer

Just a quick heads up to all Prusa MINI, MK4 and XL users who are using the latest Prusa Slicer. The printer settings in the latest Prusa Slicer have been updated and the bgcode file format is now the default export setting - which will probably cause confusion for some users, because OctoPrint doesn't support bgcode. quick faq: What is bgcode? the B in bgcode stands for binary. Regular gcode contains ASCII text (normal readable text), while bgcode contains (mostly) binary data. In additio…

Thank you very much. I had everything working fine until updating slicer and then also reinstalling Octoprint with newer image.

Yes on mini display the Octoprint interface (rather than the default Prusa mini interface) should be displaying, (or at least it did in the past while it still worked until update).

I have now been on the web and then unticked in Slicer the "supports binary G-code" and now when in Slicer "upload to printer and print" I get a new slicer message saying "COMPLETED" but nothing prints.

I have also in added the bgcode/ plugin, but no printing happens, even though Slider message says the file uploads and prints to printer

Thank you for link, but the Prusa write-up didn't solve it.

Another notable issue: I can connect to Octoprint (no wired connection, I have WIFI) in browser http://192.168.0.37/#control, but not with http://octopi.local/

I think the problem remains that Octoprint interface does not load to Prusa Mini display panel.

Hi, It is now working.
The problem was that in Slicer I had not added a printer but had used the default just as it was on the Octoprint image.
Also in Slicer, Configuration/Preferences/other I have unticked "use binary G-code when the printer supports it.
Also I added the b-code plugin to Octoprint

The last issue that remains for now is that with browser I can not log in Octoprint with http://octopi.local/ but I can with http://192.168.0.37/#control.

Finally I should add that Octoprint interface comes up on Prusa display panel when a printing job is being uploaded. Apologies that I had forgotten this default behaviour on Prusa mini display panel

Thank you so very much for your great support.
