OS Version

n/a

Additional system information

Printer

Bambu Labs A1

How to reproduce

Select Bambu Labs printer
Navigate to Prepare > Process > Global
Note that under Prime tower many of the documented options are not available

Open https://www.orcaslicer.com/wiki/print_settings/multimaterial/multimaterial_settings_prime_tower to understand why

Actual results

https://www.orcaslicer.com/wiki/print_settings/multimaterial/multimaterial_settings_prime_tower shows options, including "No sparse layers"

Expected results

That page would explain which settings were not available for Bambu Lab printers and why.

Anything else?

Many prime tower options are described on https://www.orcaslicer.com/wiki/print_settings/multimaterial/multimaterial_settings_prime_tower However, several of these options are disabled in commit b0bd16e908 if is_bbl_printers. As these parameters are recommended by online sources to resolve some issues, the lack of user-facing documentation of this fact can result in fruitless searches.

This is not a request to change the behavior (ref: #8031), but to document the behavior.
