You should try Polymaker ASA. It works fantastic with my X1C…
I have no idea why the X1C prints ASA as good as it does you’re not the only person who has mentioned about the X series just works. I only have a P1PS and now that I have had success using Bambu’s ASA with liquid glue I think I will continue to use it up till it’s gone. But you bring up a point about running those tests (another reason why I should have just ponied up and got the X series) the auto cali must be so nice on those machines.
I will be buying the High Temp Plate and Gold PEI Sheets to run more testing. Not sure how other people feel but when it’s working man I am still just blown away on how incredible this machine is. I am pretty excited for the future of Bambu.
