Thanks @cloakfiend
I want to print the first layer perfect because I'm printing iPhone cases.
It will look terrible if the first layer is terrible.
Anyhow, I'm trying to adjust the bed on the fly now.

Got it.
Thanks @IRobertI
You should be OK, its only ends up terrible if you really mess up and print too far away for the first layer so its better to be too close than too far. as long as it covers the base dont worry if it looks thinner in places at the start as you wont see that after the second layer, it will look perfect when its done. thats why I think measuring it precisely is completely pointless in my opinion. It makes absolutely no difference to the final print. The first layer will be slightly melted either way as its the first layer that goes on and you want good surface adhesion for the rest to print well on top.
One difference it can make is to avoid having a bunch of excess melted plastic on the nozzle that can drip on the print later. If you're too close to the platform the nozzle will drag through plastic that sticks up too far and get it stuck to the side of the nozzle.
There's also the problem where pressure might build up so high that the feeder skips followed by a section where not enough plastic is extruded. That can lead to poor bed adhesion.
But yeah, after 2-3 layers bed levelling is out of the equation.
Yes have to agree that is true, but as you said after a few layers the blobs usually do get covered up, but that does happen to me on occasion I admit! lol but seeing as its only rare and usually one one blob, you rarely see it. also you don't want it scraping against the glue on the build plate as well!
I guess its takes a bit of practice and then you don't even worry about it later, its a beginners thing to get to grips with then not even an issue later on as you can usually sort it out in less than a minute.
I've never had the pressure problem, but have heard clicks which didn't appear to affect the first or any other layers, but am aware of the whole pressure retraction thing and try not to go silly close!

Good experience.
I will keep an eye on the nozzle to avoid having a bunch of excess melted plastic on it.
Thanks @cloakfiend
I agree with you basically.
But I think better leveling will be helpful for a better result, especially for persons who has poor experience to adjust the bed on the fly (like me).
Of cause, I'm learning.
Yeah its kinda like a tap, it builds up around the end of the nozzle and if it build up enough or hits anything then it comes off.
I might do a levelling on the fly tutorial when i need to adjust it as i quite enjoy making tutorials on 3d printing.
Edited by GuestThat's great, @cloakfiend
Looking forward to your turorials!
I find it distressing that of the "answers" only a handful were actually an answer.
