Clean build plate, dry filament, flow calibration done, pressure advanced done, temp correct settings, but this section always has this happen, next to it smooth as expected. Im clueless what can be causing it.
PLA+, 230c, 1st layer 80mm
TBH, it does look like even more cleaning is needed in that area. Use a brush and do not be too gentle.
In extreme cases, you can even consider a steel wool or steel cleaning pad.

Once print done i’ll give it another good wash

Please don’t use steel wool. Only cause it’s a lot harder the the plates covering. Use brass please. And seeing those marks there where there close to the center is a point of interest This could be debis on the underside of the plate. Scrub BOTH sides good with a brass wool. (might have to ask the counter for it depending on where you live. The stuff is used as a filter for smoking meth. Bad Apples.) I like to use dawn to soak them in and use the hottest water you can for a rinse. Then wipe down with 99% Isopropyl Alcohol.
As far as adhesive , the Bambu stuff is great. I spray the plate,(Eyeglass cleaner sprayers work great) with alcohol first and while wet spay on Bambu’s adhesive. (There’s a trick to getting their applicator off. PM me is needed. Mix it all up with a little chunk of rubbery foam and try to just get it everywhere. Then gently dry it with a microfiber and i should be good for a Bunch of runs with nly IPA wipe downs in between. Also do the last step when cool. And one last tip: if you find you need to use the other side of the plate but don’t have time to clean, just put a thin sheet of nonstick aluminum on the hot bed. Being Aluminum it won’t stick to the magnets, But I can’t express enough NON-Stick Renalds Wrap.Well, it’s probably pat everyone’s bedtime now. Sorry to be so brief. I’m old…

This looks like grease. Your plate may have grease on it (residue from your cleaning), so wipe it down thoroughly with a clean microfiber cloth and nothing else. No alcohol, as you’ll just end up smearing the grease around to an even distribution rather than actually removing it.
However, as it’s PLA+ there’s also a minor chance that this is too high flow rate. This issue can create the the waves you’re seeing here, but it’d be more even and throughout the first layer, and not only in some specific areas. But if wiping the plate with a clean cloth doesn’t change much, try calibrating your pressure advance (K-value).

I have read some reports of bad or non -flat HB’s. And it can effect the leveling as the plate can flex if the bed is not flat. Place a straight edge across the bed, edge to edge and shine a light from he back.If you see a line of light between, not involved with the magnet placement, it’s a bad bed .But those folks said a replacement was sent at no cost. They don’t post it publicly but even though I love my A1 i too have it locked down.But they want need to Rock The Boat Baby in the middle of a multi-gazillion dollar lawsuit. But I guess that’s why they are inexpensive relatively . Get your spare parts now.

Thanks for the tips and info, was late after print so im going to wash it down tomorrow as well as giving the actual bed a wipe also. Will do another K value also and make sure its correct.
Gave the plate a good wash, I changed to a 0.6 nozzle and first layer looks great, will test with 0.4 once swapped back. Thanks for the help.
Cleaned with hot water and dish soap, k value correct, temp correct, bed levelling done you name it.
0.4 nozzle still doing it 
This is after a cleaned bed etc, once first layer is done its fine, think its my textured plate?
Update again:
Did a full printer calibration, cleaned bed again, STILL getting wavey lines on first layer.
First layer is 0.2mm, could this be the issue? or is my nozzle done already after 4months? I dont use it that much to ruin it.
Have you ever checked the screws of the heating assembly since you bought the printer four months ago? See the wiki below for details.
Those waves might be created by a wobbly nozzle. Your first layer print looks a bit like the layer in the first picture on that page.
I checked the heating assembly about a month after I bought the A1 and three of the four screws the needed to be tightened.

Thanks very much, will give them a maintenance later once its all cooled down.
Weirdly, changing my K value from 0.018 to 0.016 and flow to 0.99 from 1 kind of resolved it, well, made it much much cleaner! will tighten the screws later though juuust incase.
No wiggley lines, just a taaaad over extrusion, but I can live with that.
I also disabled Scarf settings thats now is enabled by default in Bambu Studio latests Beta, before that was disabled in last public launch, so I have copied that over to beta and seems to be much cleaner now.

Okay, sounds good. A flow rate of 1 is in my opinion a bit high anyway. I have 0,96 to 0,98 for most of my filaments. In BS you can calibrate the flow rate as well. Maybe it is worth a try.
Weirdly enough I did and it caused more issues, but setting it back to 0.98 or 0.99 fixed the issue.
Not sure if its a bug or not, but manually calibrating the flow is what gave me the inconsistent lines… hmmmm
Solved.
Did a bed tram again.
Adjusted hotend belt
Adjusted bed belt also
I think this was the culprit, one of the 2 screws on the side where loose, belt was a little loose and the tramming was way off since the day I bought it.
Back to like day one.

I am yet to receive my A1 Mini (arrives tomorrow), so I am just needing out right now.
You folks all seem to be pretty knowledgeable at this and the troubleshooting. Do you have any tips for my initial setup, or will the QR Code and setup video suffice?
Also…should I be ordering extra beds now? How long should I expect one to last?
Thanks in advance.
That’s a loaded question.
Depends on many factors. How much you print, how you care for your plate, your filament, your printer. How keen you are to see things before they actually happen.
You’ll probably be fine for quite some time. I’ve got several hundred hours on a few printers using original bed plates. Extras are always nice to have on hand for swapping out plates to start a new print before the previous one cools down.
If you’re starting out with PLA, it’ll last and be fairly easy to maintain. PETG not much different.
Bambu really has a nice user experience compared to others. I’ve got others, their good at printing, but the user experience on Bambu is next level.

Much appreciated CRracer712.
I’m as green as it gets in this world. So I’ll likely take it slow.
Bought this machine so I can mostly make router templates for my carpentry work.
But I’m certain I’ll find cool stuff to do with it along the way. 
If you do carpentry work, you’ll get along just fine on your printer.
Iv owned printers that need full manual setup, so I have been use to tinkering. Bambu’s are different, solid little machines, having a dedicated forum to the machine you own is great also, where as other forums its all types of printers and getting information is deep browsing.
I like to ask on here still as most issues have been resolved by someone else if its “common” such as quality degrading after few months use, as its bound to happen as the printer has bedded in, things have loosen over time etc and its just knowing which to troubleshoot by looking at issues with say a print.
Welcome to the Bambu club, Im sure there is lots of models for you
