How are pass strips or corner solutions installed?

Hello I designed my Faktum kitchen with the online planner. Everything looks good. I have already read some assembly instructions and can well imagine how to assemble the individual elements (base cabinets, wall cabinets, etc.). What I absolutely cannot imagine right now is how to install filler strips or 65x65 corner solutions. In the picture, I entered a filler strip and a corner solution next to a base cabinet in the planner. How exactly is the filler strip installed? Is there an assembly instruction for it? When I create the parts list in the online planner, I see a 59.5x70cm side panel listed. I assume I have to cut it to the required width myself (or have it cut). Do I also need edge banding? How is the filler strip screwed on? What about the corner solution, since the online planner also only adds a 59.5x70cm side panel for it? Do I need additional legs for the baseboard of the corner solution? Or do only the base cabinets standing at the corner need two legs each on the corner side? Who can please explain this well to me? Regards Section Chief

In the meantime, I have found this thread here:

However, not all questions are answered by it, such as edge banding or corner solution?

Here

the question about fitting strips is actually already well explained, what I would still like to know is:
Do the end panels, when you buy them from Ikea, already have edge banding/veneers on the edges or do you have to buy and iron them on separately?
If I use a cut-to-size end panel as a fitting strip, then I need the edge decor on the side that faces the base cabinet. If the Ikea end panel has the edges already veneered, then I can only make max. 2 fitting strips from one end panel, right?

The cover panels are laminated/varnished/veneered all around. As far as I know, apart from the base, there is no edge banding included. However, I am not completely sure. You only need the edge banding if the alignment panel is not supposed to align with the fronts, but with the carcass. If you want it flush with the fronts, it would also be better to cut up a door, as the cover panels are significantly thinner than the fronts.

If you want them to be flush with the fronts, it would also be better to cut up a door, since the side panels are significantly thinner than the fronts.

Great, thanks!
How are filler strips/corner solutions usually done: flush with the front or with the carcass?
At first, I would have assumed they are always flush with the fronts. But the online planner adds side panels to the parts list when you insert a filler strip. So it would be in the same plane as the carcass.
I have to check once how this is solved at the Ikea display kitchens.
Cutting up a door won't work so well with Lindigö fronts because of the relief.

Edit: I have now checked it in the online planner. It places the filler strips in the same plane as the carcass, which is why it also adds side panels to the parts list.

By the way, in your dead corner I would support the countertop with an adjustable support leg. A ladder anchored to the wall serves the same purpose, but I find it not so easy to get it to an exact height.
