Support for ABS sticking to print, Top Z Distance will not solve it

Recently, I’ve been working Support for ABS trying to get a print to work.

When I use Bambu’s specified settings, particularly “0 Top Z Distance”, the Support material (interface) really sticks to my print instead of the support base. With a good amount of effort I can peel it off, but it’s too much effort for a larger print. To be clear, it comes OFF the support base, instead of my printing becoming detached from it.

The obvious solution, and the one suggested by BBL is to increase the Top Z Distance, but this is even worse. At any Top Z Distance other than 0 mm (including 0.01 mm), my print warps because it isn’t properly adhering to the interface (I assume 0.01 mm is jumping to a much larger minimum Z-step increment).

So 0.00 mm is too little, and 0.01 mm is too much. My print settings are identical to BBL settings in the Wiki for Support for ABS. The general Wiki section for all support materials only lists Top Z Distance as a method of adjusting adhesion tolerance.

What are some options here?

Found by searching in the forum:

Hey Mate, was this printed at 0.2mm layer height or higher? I’m finding that 0.2mm standard BBL profile is perfect, 0.12mm is unusable.

Also, make sure the filament is dry.

That was my comment lol

Turns out BBL has no advisory but 20 mm so far is the only successful layer height.
