I’ve been noticing some delamination (layer separation), but only on solid infill and top layers, and only on larger surfaces

Initially, I tried reducing speed, but didn’t notice any improvement

There are no noticeable issues on short lines, so I think this is something to do with acceleration, which I didn’t realise was a thing, but there are indeed settings for this in OrcaSlicer

Update:

Reducing acceleration does seem to have resulted in less severe delamination, but it hasn’t gone away completely

So I think I need to reduce it just a little bit more

    Something to consider perhaps, Just a SWAG

    Printing temp? Too low of printing temps can cause poor layer bonding.

    Air currents. This is noticeable on open bed printers the most. But even enclosed printers can have issues with cooling fans being on too long and at too high of a speed.

      for this 230C - 250C PETG filament, i’m already at 250C (but i’ve been contemplating bumping it up to 255C)
