If the Lychee Slicer team has updated a printer/resin profile, the slicer will ask you if you want to update it during the next launch.
To force it, restart the slicer. You will be asked to update these settings and/or keep yours.
Select the parameters you want to keep/change using the arrow (the blue overlay means it’s selected.) and validate with the apply/accept/validate?? button.
If you skipped this step by mistake or want to reset a profile by default, you can open the profile and press the red icon to reset every parameter (top left corner) or by parameters.
