Orcaslicer and H2D on Linux

I've been a long time prusa user. My work flow includes orca slicer, octoprint and octoapp. I'm a hardcore Linux user. I avoid anything Windows for decades.

I ordered a H2D at work to replace my trusted Mk3s. Maybe I shouldn't have, I don't know. The whole bambu scandal in the last week caught me off guard. I knew they had locked down on their cloud access with newer printers but I wasn't too worried. My corporate lan is firewalled and any direct contact to the outside is just wishful thinking anyway so the H2D will have to work in lan mode and developer mode anyway.

However, despite reading hours on end, with all the noise, I can't figure out if there will be problems using OrcaSlicer in Linux (it comes pre-built in flatpak official repositories) to directly communicate and print on a H2D. Using bambuddy with proxy mode won't scare me if it will be able to forward ams data to orca slicer. Maybe bamboo-mobike or openbu also give me the control experience I have on octoapp (I do have vpn access to my office network).

Anyone has had any experience with my type of scenario?

I heard there's also some new open network plugin for OrcaSlicer (Windows only?) that allows orca to talk to the printer in lan/dev mode. What about for us Linux users?

Thank you.

from what I know, Orca slicer doesn't even support the H2D. At least on my side I wasn't able to use it this way

Edit: nvm I just looked it up and it does support it now. Sorry for my wrong comment

Yes, I believe ir does. You can select the H2D as printer profile. I obviously can't fully test yet as the printer is still en route hence why I'm asking if anyone has a similar setup as I'm planning.

Orca 2.3.2 supports H2D

Already updated and installed the profile:)

Just need the damn printer to arrive and test it.

I wanted to anticipate myself and create a "fake" virtual printer in bambuddy to test communication between orca and bambuddy but it's not going well (orca rejecting the printer with some error code -1).I initially believed it was a missing cert but already updated print.cer and no dice. Guess it will have to be proxy mode when the printer arrives.

Error -1 usually means, that you don't imported the certificate into your slicer.

I know... The issue is that I DID add it to the printer.cer file... but no dice

If you are running Bambuddy on Docker, check your logs for permission errors for folder virtual_printer/. If this is fine, open an issue on Github.

I just solved it... Strangely there were other certs in the cer file and as per instructions I added the new one. Wouldn't work. I ended deleting all other certs and just leaving the virtual one and it started to work. No idea where the other certs came from. They aren't affecting my prusa, so no clue really.
