What's the thinnest layer height the MK3 can print?

Right now I'm doing a print at 0.05mm layer height, and it seems to be coming out fine. Makes me wonder now just how thin the limit is. Anyone know?

Depends on material (filament) and also manufacturer of filament moisture, calibration data etc... lets focus on filament.
PLA (prusa and fillamentum): 0,5 on treefrog but better to use dynamic layer high and there is minimum 0,7
ABS (prusa and fillamentum): I never had successful print lower then 0,1 (mean whole one, not dynamic layer high)
Nylon Carbon (fillamentum): best results on 0,1 however manufacturer suggest layer high between 0,4 and 0,2
PETG (prusa): Never feel need to print lower than 0,1
CPE (fillamentum): 0,1 or 0,2 lower layer high has inadequate quality
FLEX 92 (fillamentum): only 0,2 and with huge problems on mk2s on mk3 no problem.

University: MK2S upgraded to MK3 with MMU2.0
Home: MK3
Materials: ABS; ASA; PETG; PET; PLA; Nylon; Nylon Carbon; CPE;
SW: Freecad 0.18; Slicer PE And still generating more troubles than whole forum together.

Since 0.05mm in PETG is lower than any of those numbers, I guess that's the limit then.

It may be possible to go smaller then 0.05mm with a smaller nozzle than the 0.4 but you would probably run into bed levelling resolution issues. Your bed would have to be ridiculously level without using the bed levelling feature.

Also the limit of 0.7 in variable layer height can be adjusted. In Slic3r it is in Printer Settings/Extruder 1/Layer height limits. 0.7 Minimum makes sense if you have a base layer height of 0.15. However for 0.10mm base layer height prints it can be safely reduced to 0.5mm. You may need to adjust the extrusion multiplier from the hard coded values (of 1 for 0.05mm and 0.95 the rest,) to 0.97.

Not really, you can still do a thicker first layer.
