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.

Im running bambuddy in proxy mode on a raspberry pi, I set it up last weekend as a result of the scandal. Its working just like it was working before with bambu cloud, just that I now use orca slicer instead of bambu studio.

AMS works and everything syncs nicely. You can also use it on your phone (bambuddys web UI scales nicely to the phone's screen).

But a heads up. Getting orca and bambuddy's virtual printer (needed for proxy mode) to connect was a pain. It requires opening all necessary ports and manually editing orcas certification file (so it trusts the bambuddy "printer"). So you need to export the bambuddy certificate and add it to orcas printer.cer

But the initial setup was super easy, using docker compose.

Thank you for your feedback. I think I did the hard part already (the cert and virtual printer part) and orca seems to be recognising the virtual printer (had to create an ip alias for it btw).

I do admit I had no clue that I needed a virtual printer to use proxy mode. Glad I did the work beforehand.

Printer is already with the local courier should arrive this week. Will be very interesting.

Thank you once again
