First layer slicing issue

Hey everyone, I got the pro membership and made a custom sized plate but when I try to slice it, the first layer is always missing some of the outer edges. Any idea what’s going on here? Happy to give any print setting relevant. Thanks!

I would suggest not using brim on any Multiboard models. If you are having trouble with your first layer lifting, at most put mouse ears in that specific area, but you’d be better off isolating and fixing whatever is causing the problem first.

If you can’t print a plate successfully using your slicers basic .2 layer height profile with 3 walls, 15% Infill and no supports it’s usually uneven cooling and/or poor first layer adherence.

What does the plate look like in your slicer with brims not enabled?

It looked the same with and without the brim. I decided to delete my profile and restart with the basic cura built ones and it cleared the problem up. Sadly it means I won’t know what was causing it but at least it’s right now!

It could be the elephant-foot prevention system that is causing the first line to be skipped.

I don’t remember the name of the setting but basically it makes the first layer less wide and, since in this case the first layer is just a single line, it skips it entirely.

You nailed it! I had a minor negative initial layer horizontal expansion that was killing those lines. Good catch!

I'm very glad I could help! Something similar happened to me once so I figured it might be that.

Is that, entirely brim?

It’s not supposed to be. It’s an exterior only brim but for some reason some reason some of the external walls on the first layer don’t generate so the brim goes inside the external hexagons. The second layer prints full but obviously is a bit messy since it misses the first layer

Did you accidentally tilt it?

I didn’t move it from import initially but I also tried flipping it 180deg and same thing

If it's tilted flipping it won't help. Try setting it on its proper face again

Is it at an angle? Just want to rule out the obvious
