Issue with overhang first layer and support bridging
I'm having some issues with overhangs as seen in the xyz cube, the first layer of the overhang for the "X" and "Y". I think it is a similar issue as the first layer that use supports also don't turn out great.

Hey there again, maybe not directly related to your overhang issue but I'm seeing some bulging on the corners of the cube especially in that picture of the Y axis. Have you calibrated pressure advance?
No i haven't is there a guide to calibrate that? Yah on the Y that's where the seems end, and in the middle there's a gap, there's the way it ends up being sliced, I figure it was a result of that
This guide in general is a really good place to start tuning.
alright thanks, i'll try that out and see what the cube ends up looking like
I did the pressure advance which between 0.05 and 0.06 it looked good, it was originally 0.05 so I tried 0.06, there wasnt that much change, a bit for the corner but the hangover still isnt great
I got a video if it prnting the hangover https://clipchamp.com/watch/7pRLsfAW0g0

I would say it is just too high expectations. I consider examples as quite normal
Even the layer on the support? There isn't any way to improve that, even just the hole turns into a semi-triangle for the first few layers

My choice here would be 0.035

0.035?
im not that experienced but why not 0.06?

See the explanation of how to choose the right setting in the linked guide above. 0.06 in the test print has maybe too much gapping in the corner feature.
yah idk, to me 0.055 has the best gap, 0.06 it starts to spread a little bit. It was 0.05 when I first printed so I wanted to see the result of a slightly bigger change. To me 0.035 has no gap and you can see it is overflowing even. I'd like to hear his thoughts on why @asychev chose 0.035?
This should be higher megapixel if discord doesn't downsize it

Gaps between extrusions is clearly visible on 0.06
Still 0.035-0.04. Check end of lines too, they also start to fall towards the middle of model
0.05 is absolute max for me
Anyway, chose min and max usable numbers, print two parts, check what looks the best for you.
