I just updated my software and it won’t let me use the printer (mini)
It acts like I purchased a new printer.
What is Host Type
Device UI
API/Password
Thanks
Under Host Types, it gives 6 options.
I don’t know what to pick.
Log out and back in via the Studio home page.

I’m going to shut down everything, then see what happens
I shutdown the computer, logged out studio, resliced.
That cleared up the other problems
With old software 1 hr 30min, new software 5hr 18 min
There’s something I’m over looking.
I don’t know what the settings should be other then what I normally change.
Here is filament settings, is there something wrong that would extend the time?
The old software I used most of the default settings.
Should density be 0?
You created this profile from scratch?
I’m not sure what a density of 0 will do to the slicer, but you might consider making that a PLA type number around 1.25.
You cut off the part of the profile that’s most important when it comes to speed, the Max Volumetric Speed parameter. What’s that set to?
Also, while I’m not exactly sure what “shrinkage” is (other than the Seinfeld episode), 100% shrinkage seems like the wrong magnitude value. Just guessing at what it means, a value closer to 1% would seem more appropriate. I think it’s how much the plastic shrinks as it cools.

This is the first slice after the software up grade, the red circles is what I changed. I only change the most common settings. 90% I don’t have a clue what they are. Here is the other.
If you hover over a parameter you will usually see an explanation, or it may change color and become a link to more information.
A density of zero should not affect the print time. It is only used to convert the calculated length of filament to be extruded into an estimate of the weight of the filament needed. So the estimate would be zero grams of filament used but the length estimate should still be correct.
100% is the correct number to use for shrinkage until you have measured an actual print and have calculated the correct adjustment.
It’s hard to say why the estimated print time increased so much without comparing actual project files. I have noticed that OrcaSlicer has been inflating estimates lately. An estimated 11 hour print recently completed in less than 9 hours.
Thanks:
The slice doesn’t show cost or grams.
Seams like every time I up grade Bambu Studio things get worse.
I don’t know why the time would be so far off?
Could the …Quality…Strength…Speed …default settings be wrong?
I guess I could delete Studio and load an older version, but I would rather not.
No matter what you set the print speeds to, the slicer is going to limit the speeds to what it thinks can be pushed out of the nozzle. The max volumetric speed of “2” is much too low. That’s why your print time is much higher. Change it to 12, a safe value to use, and reslice.
OK. Shrinkage’s meaning was exactly opposite of my guess. Ignore that advice.

A flow of 2 can explain the time increase. Most normal PLA had 12 with high flow being 20+.
In my prints, I se a lot of flow limited volumes.
I thought the default settings got you real close. If I would have known, I would have copied all the settings of the old version.
The oldest version was best, no problems, then when I went to the next version it turned into a pooping machine (no AMS), now this. With your help I’ll get through it. THANKS
Generic defaults are usually a good starting point.
Flushing volume (i.e. poop size) is something to look out for with every Studio update. Bambu has been trying to optimize that for a while but frequently, things went wrong during updates. I had the flushing multiplier set to 0 during 3 different updates which can be a hughe pain with a print-forget printer.
Happy printing, 
and Merry Christmas

Changed some settings, that made a big change in time
Thanks

I’m printing, it drew a line around and away about 1/8" from the part, it’s still cuts the filament after the second layer.
I’m up and running, THANKS
Excellent 
That sounds like you have a single line Skirt. Depending on the printer, you can set the number of skirt loops to 0. However, having a nozzle prime line somewhere on the plate is helpful. My X1 does that at the front, my Plus 4 has a L-shaped pattern close to the part. Both are part of the Machine Start GCode (see later).
On a multi-color or multi-filament print that would be normal (depending on coloring/support interface settings). But on a single color print? That would be odd.
If you are certain that you have sliced for a single-color, single-filament print, you may want to check exactly when it is triggering the filament cut. Right at the start of a layer change? In that case, it may be worth to click on the two symbols I circled in the screenshot below and paste the Layer change GCode here in the forum.
I need to head off to bed but there are plenty of experienced folks here who know more about GCode than I do.
Printer is about 9 months old, it started cutting the filament, I think, the second up grade. I only get into the common settings, I’ll check it out, THANKS

Skirt Loops was 1, I can’t find if it’s single or multi filament setting.
This is all it shows for “Layer Change”
It might save some time and be easier for us to see what is happening if you could upload a 3mf that produces the problem. With no AMS, printing only a single color, it should not be flushing or cutting the filament at all during a print.

Single- or Multicolor is apparent from a screenshot of the preview with the “Filament” overview. Or the pop-up window when you send it to the printer.
The Layer Change GCode is much shorter than usual. There should be a few “if” regarding timelapse. Nevertheless, there’s nothing there to explain a superfluous cutting.
I agree with @lkraus that it may be neccessary to just copy and paste your 3mf here in the forum. The cherry on the cake would be a video of the cutting at layer , ideally with the display visible.
