I keep getting random spots on my first layer where the lines don’t meet each other and leave transparent areas, every time in the same spots

what do you clean your print bed surface with?
dish soap, using a soft sponge, like in the tutorial from bambu
Read This:
already did that a couple of times
They do not recommend a soft sponge. Look here (Bambu Lab Textured PEI Plate Troubleshooting Guide | Bambu Lab Wiki), you need something stronger. This default textured plate has small pieces of plastic when I look at it and zoom in. Also quite hot water. It’s the only way I managed to remove those very small pieces of plastic, and possible oils or wahatever.
If those spots were not random, then it was probably a bed leveling issue. But you said those are random, so it could be the plate (dirty), it could be draft, or filament that is not dry or calibrated.
i am having a tough time at the moment but i will try as soon as possible
also, do i have to cover the plate every time i am not printing to avoid getting dust on it?
In my opinion its only nessecary too cover your build plate if you also deem it necessary too cover your sofa when not in use (In other words no just clean regularly)
Because of that reason and also the fact that without a good first layer stuff doesn’t stick I have actually started using glue and no longer have that issue there’s a good video on YouTube about using glue where you do the cover the whole thing One Direction let it dry and then do the perpendicular Direction next. I’ve also noticed that when I increase the speed but didn’t increase the temperature first and that’s the temperature of both the bed and filament
is the harder green part of a dish sponge good for that?
I guess but depends. Some of those sponges have a hairy green part, and that may cause more problems than solve. I don’t use the dishwasher sponge anymore, I use something stronger, more abrasive, and a brush. Seems fine.
Not going to lie, I use 2 pieces of paper towel (one for a splash of super hot water & the other to dry the plate). I do it every day before printing or if I start to see my first layer failing. Because we dont have to add adhesives to the textured PEI plates for printing, your only main concern will be oils and dust particles. Hope this helps!

I think this is within spec, do 2 layers and see how it looks. Ultimately it could very well be due to small imperfections in the bed, I have seen weirder things in the past. If your other layers seem to come out ok then you should be good. That amount of under extrusion on a first layer really isn’t cause for concern IMO.
If you are really concerned about it try raising your bottom flow rate to like 105%

I am having the exact same problem and I am trying to isolate it.
