Hello everyone,
Recently I purchased a secondhand X1C after having stopped with 3D printing for a few years with a Creality Ender 3.
So far I really like the X1C, and it’s a world of difference compared to the Ender 3.
There’s alot less manual tuning needed for the X1C, but I still want to try to get the best quality possible and try to prevent misprints.
I tried looking for calibration tests that could be used to further finetune the printer and filament settings, and there’s quite a bit of information, but it seems the information is a bit outdated.
Most of the information I find refers to using the calibration tests from Orca Slicer to finetune the printer, but I don’t think it’s not really a good option anymore after the recent happenings between BL and OS.
I did try to export the pressure advance calibration from OS, and import it into BS, but when I printed the model there wasn’t any difference in the corners, and in BS there was no option to turn off pressure advance (I did turn off flow calibration).
So I wanted to ask those who’re more experienced with finetuning their X1C and filaments which kind of calibration tests they use, and where to find them.
I haven’t updated yet to the latest firmware exactly because of the lockout of Orca. When I feel the need, I will still use Orca and transfer the GCode with Bambu Connect. It’s just so much better than BambuStudio in many respects.
For tuning flow and pressure advance, I use the automatic calibration with the Lidar in either BambuStudio or OrcaSlicer. It gave and still gives me better and more consistent results than manual calibration with Orca. As I haven’t done calibration for all my filaments, most of the time I enable automatic calibration at the start of the print. That also significantly reduces the number of material profiles that I have to handle. E.g. I have only two profiles for PLA and 3 profiles for PETG instead of like 20 for every roll. That way I also don’t have to recalibrate flow when I replace an empty roll.
One more thing that I calibrate is shrinkage to get exact dimensions, using my model and guide: ShrinkingTest V4.1 by Alex_vG by Alex_vGMakerWorld: Download Free 3D Models
In the beginning, I did the max flow test from Orca for most filaments. As all filaments so far were more or less above 20mm³/s I just set max flow to 20 for all filaments. Since I have switched to the E3D Obxidian 0,4mm nozzle, I have increased that to 35mm³/s and reduced nozzle temperature by 10-20°C.
As a basis for 3rd party filament, I use the BambuLab filament profiles (not the generic ones).

All right, thank you for your reply. Sadly I bought the X1C after the controversy with Orca, so it was too late to downgrade the firmware. There’s probably a way to still do it, but I don’t want to brick the printer.
So far I’ve sticked with all the Bambu profiles for filaments, as I thought that that was probably the safest bet. I’ll try out the test you’ve linked. 
I haven’t tried it yet myself, but Orca + Bambu Connect should work just fine for you. It’s a few extra clicks, but not a show stopper.
I might buy the new AMS HT so I will be in the same boat then.
I read somewhere that there’s also some jailbreaked firmware version for the X1C, but like I mentioned above I don’t want to risk getting the printer bricked or anything, especially since I bought it secondhand.
I did try Bambu Connect, but that doesn’t seem to work, apparently there’s some mismatched 3MF versions between OS and BS
I tried looking for a beta version of BS to try and fix the error, but I can only find the latest official released version. This error happens when I export from OS to a 3MF, and import it into BS. If I try to import it through BH I just get a flat error message.
that is not what I would have expected 
No idea how to solve that.
