Hello forum! I have this ridiculous problem that I just don’t know how it happened.
All my printer presets just vanished out of nowhere and I can’t get them back. Instead it shows “default printer”:
What’s weird is that it shows my current printer I have selected when I check “Select/Remove printers”:
Which means that my printer is available, it’s just not showing in the select option.
What’s weird is that every time I close and reopen Bambu Studio, the setup appears (which is supposed to happen only once, when you are getting into Bambu Studio first time)
Before you say it, yes I already tried logging out and in and did not fix the problem. I don’t recall installing any updates before this so I like to say that this problem just occurred out of nowhere when it was running fine(I could be wrong though, I might’ve installed an update and I forgot about it).
So I am out of ideas and I would like some help please…
I had that happen once, I just went through the setup again (skipping what was already there) and logged in & everything was back.
Unfortunately, I already tried the logging tactic and it’s not working…
Ugh, I tried uninstalling and installing but it still did not fix the problem. I need to print something but without the available presents I cannot the correct information on my print
Did this ever get resolved. I am currently in this exact situation and Ive tried everything to get both of my printers back to no avail.

I have this EXACT same issue. It seems to have been triggered by Bambu Studio attempting to install an updated TPU profile for the A1 which I was prompted for when I opened a new model from Makerworld today. I have made no other changes to my machine or config and it was printing normally yesterday. Logging out and back in to Studio changed nothing.
I cannot detect nor select my configured A1 printer (it is in LAN mode) and when trying to setup a printer the A1 is already selected in printer types but does not appear in the printer selection dropdown.
This issue is found all over Google and Reddit with no official acknowledgement or fix given anywhere I can find.
Bambu you have crippled our printers, provide a fix.

Same exact thing just happened with me. I can see both my X1C printers in bambu handy on my iphone but can not see them nor can I rebuild the profiles in bambu studio. I can’t even add bambu printers under printer selection. I was just loading a 3mf file and this happened. What gives?
Same here. I can get my existing presets back after yesterdays software update. Thats a years worth of work and fine tuning.

Same! I finally caved on the TPU update thinking it was time… wouldn’t be there still if there were issues… right? Nope. Irritating. Now I can’t seem to get the new software that SAYS it fixed the issue to download - click the download button, it jumps from Bambu Studio to web browser with makerworld and nothing. 
Frustrated.
Same. Sooooo frustrated right now. I don’t even have an A1 mini.
