Elephantfoot compensation for SL1S
Description of the bug
When i print a part directly on the buildplate i get a huge (approx. 0.5-1mm) elephant foot on the part on the SL1S. This was not so noticable with the SL1. Settings in Prusa slicer are 0.2mm/0.2mm for the elephant foot compensation. When looking into the slices it is noticable that prusa slicer only reduces size of the first layer, all the following layers are of full size. Also reducing the first layer time to reduce light bleeding makes nearly no difference.
Suggestion: Correct the e.g. first 10 layers with a transition ramp, like it is for the time of the first layers.
Project file & How to reproduce
How to reproduce: Drop attached stl file (like it is flat side on build plate) direct on the buildplate of SL1S without supports. Use elephant foot compensation options of 0.2mm/0.2mm White Elegoo ABS like resin with 25 sec for first layer isfdKnobGenericCover new.zip

SL1 upgraded to SL1S
Most resin prints should be printed with a pad and supports, where an elephant foot wouldn't cause any issues. But for models with a flat surface to place it on (even though this is not ideal), something like this would be useful, I agree.
I completely agree! Had the same thought. This and the ability to control rest time before the UV activates (separate from tilt time) would make printing parts against the platform much easier. Personally, I print all my parts directly on the platform if possible, as I print mostly intricate mechanical components, where sanding away support marks is not ideal, and all surfaces are critical.

Same here just upgraded and what a disappointment. My everyday prints are affected by this issue all worked perfectly before.. Control over transition layers is necessary ether with time or LED power output (not sure if possible) .
