Support Initial Layer not adhering to bed

I feel like I must be missing something, because some of my supports adhere really well to the plate, and others don’t at all for some reason.

Both supports are from the same print. The larger one is as i would expect it, however the smaller one always ends up like this. I’ve tried increasing the initial layer expansion with the same results.

This is with BambuLab PLA Wood filament.

Is it like this for everyone? is this normal? The issue appears to be that the first support’s base is printed at the correct “Initial Layer Density”, and all others seem to be printing at something like 50-60% density instead of what it is set at (100% in my case).

When I print the same model with Basic PLA, that smaller support seems to still hang on throughout the print, however when using PLA Wood, it comes off and the print fails. I’ve tried using glue, though it seems if the other supports had full bases like the larger one, this wouldn’t be an issue.

I am not an expert, but I had similar issues with BambuLab PLA Wood. First layer wouldn’t stick to the build plate, whether it was support or the part itself. Specially on small structures (like 2 or 3 lines thick), the filament didn’t stick.
What helped was

  1. clean build plate before every print with soap (plain, no skin lotion stuff)
  2. raise the build plate temperature by 5 degrees (or more)
