Sorry for the late reply. Looks like the majority of what you still need to level is Prime things. If you weren’t already aware those can be acquired from Void Relics. A large majority of the ones you still need to level are vaulted. Luckily two frames and their associated weapons are un-vaulted each month. You can check to see which are from the market in your ship under Prime Resurgence. Or by going to Maroo’s Bazarr on Mars and talking to Varzia.
The next large chunk of items are the Kuva and Tenet weapons which you get from the Lich system. This would probably be the most time consuming behind the Prime items you’re missing. For a full run down of how that system works i would recommend just checking the wiki page.
The rest are kind of scattered about so you can always refer to the wiki as to how to acquire them. The one exception to that would be the compainion weapons which you will get from building the normal and prime variants, leveling the Sister Hounds (which you will get from interacting with the Lich system), and leveling the Moas from Legs in Fortuna.
Hope that helps!
LR4 here, the screenshots might help with suggestions on how to obtain things in a timely manner. One thing to note though is that a lot of veterans like my self who have been playing for close to 10 years have been able to pace ourselves with the release of content to some degree. So while the total number of MR based items may seem high, it wasn’t always the case.
This is really a head scratcher. I’m no Klipper expert when it comes to really tinkering with the printer.cfg, however if I was in your situation the next place I would go with troubleshooting would be on the firmware side of things. Klipper already makes regular backups of your important configs so maybe try making a copy of them and do a clean install of Klipper with a default printer.cfg for your printer and see if that helps narrow down the issue some more. Saves you having to spend money on hardware if you don’t end up actually needing it.
As far as weapons go you’ll want the Galvanized mods. You can get those by doing arbitration missions which cycle every hour. In those missions a specific enemy called Arbitration Drones will spawn. They are immune to all warframe abilities and give that immunity to nearby enemies. When they die they have a chance to drop a material called Vitus Essence, which is used to buy the Galvanized mods from the Arbiters of Hexis syndicate at a relay. The mods you’ll want to prioritize are the multishot ones.
As for your issues with your frame survivability, you’ll have to give some more detail on who you’ve been playing and I can make some suggestions for builds.
I would consider looking into Klipper. That would be a fantastic upgrade and there are plenty of videos on how to go about it. The documentation for the project is also easy to parse.
It was the first major upgrade I did to my Ender 3 that I got back in July. Way too spoiled by it at this point to go back to Marlin.
