you open the device tab and you see a white blank screen

(I am currently facing an issue with Orca Slicer where I cannot access the Devices tab on the latest version, as well as previous versions like 1.7.0. Whenever I try to access the tab, all I see is a blank white screen. I would greatly appreciate any assistance in resolving this issue.)

being able to send my Sliced files to my printer over my network from my laptop

I just updated to 1.9.1, and I am still having the same issue. My screen looks the same as Irishman0816.

Same behavior on windows 10. i was looking at the logs and there is no updates to the debug log at all when i select the device tab. it seems the tab does nothing at all... i see it loads the about:blank page, so i assume there is something wrong with the "url" where it starts loading the page.

i got that info by right clicking and selecting "print" and it shows the url on the top of the print preview. so it has something to do with the built in browser.

Could you show me where the "print" button is? I am not able to find it :D

I am right clicking on the blank screen and the print option shows up.

Ah I see thank you I also have just an 'about:blank' page in the print view and it doesn't show any obvious errors in the logs as well

It seems to happen if I've left Orca Slicer open for a long time

Mar 06 '24 21:03 norris108

Same here when trying to connect via PrusaConnect, while PrusaLink is working!

Orca bot: this issue is stale because it has been open for 90 days with no activity.

This has been fixed for me. I dont know about others but I think this can be closed.

Jun 20 '24 00:06 technomooney

Yeah I don't have this issue anymore as well I'm going to close this if I am even able to do that :)

Jun 20 '24 06:06 HandsomeToast

I've not had the issue for a while now

Jun 20 '24 07:06 norris108

Version 2.1.1 on an Apple Silicon Mac is showing the same behavior. Clicking on the printer connect button, restarting octoprint, and reinstalling OrcaSlicer all didn't seem to fix it.

I am seeing the same result - no connection to the printer and a solid blank screen - in 2.1.1 under Linux (Debian, Fedora, and Ubuntu). It was working in 2.1.0 BETA. Using a standard browser and connecting to the printer shows the Fluidd interface properly.

Not sure if this fixes your issue, I had the same thing with a white screen on the Device tab. It turned out that I was using octoprint over HTTPS with a self signed certificate. Switching to a proper certificate signed by letsencrypt fixed the issue for me.

I also see this issue with 2.1.1(amd) on M1 Mac. I don't have octoprint, so that is not a fix for me.

I'm a new Octo Slicer user. I get this on 2.2.0-rc on MacOS (ARM) 14.6.1 with a printer running via OctoPrint 1.10.2.

I'm a new Octo Slicer user. I get this on 2.2.0-rc on MacOS (ARM) 14.6.1 with a printer running via OctoPrint 1.10.2.

In my case, the problem was that I did not understand what to write in the "Device UI" field in the physical printer dialog. Once I wrote the hostname of my Octopi host ("octopi.local"), I did get the web page login in the Device tab.

It would have been helpful to get an error like "URL xxx could not be loaded" or something similar.

I'm also new to Orca Slicer and have 2.2.0-rc on an ARM Mac. I have successfully sent prints to one of my mk4s (with mmu no less!) via Prusa Link auth (both HTTP digest or API key work), but despite that the Device page remains a blank white screen.

I'm not sure where to even start debugging this. Is there a debug console for OrcaSlicer?

It appears that this is now fixed for me in v2.2.0. Thanks!

This is happening to me still on v2.2.0

Same problem for me, has no one found a solution?

I'm also still seeing this with a fresh build of nightly, but I sometimes receive an additional message from Webkit:

WebKit encountered an internal error. This is a WebKit bug.

Unfortunately there is no further information and no useful traceback/stack info in a strace run.

For my flashforge I had to add extra parameters when connecting the printer:

http://xxx.xxx.x.xxx:8080/stream_simple.html

I'm sure other printers have their own special urls. After I upgraded to Klipper I had to change this again. Nothing wrong with orca.

i am on latest version and screen goes to about:blank after i switch out of it

Apr 11 '25 23:04 NEOLabs-software

I fixed it by editing the code For the people experiencing a normal blank screen, try connecting though a browser For me, I found a if statement for the webview that checks if I switched away Removed it
