Help Tuning Overture Matte PLA on MK4S + MMU3 for High Detail

Hi all,

I’m looking for help fine-tuning Overture Matte PLA on a Prusa MK4S with MMU3 using a 0.4 mm nozzle. My goal is to get clean, highly detailed results with minimal post-processing, especially for multi-material prints (The dream, I know).

I’ve been working from the 0.10mm FAST DETAIL preset in PrusaSlicer and need the results to work across all 5 MMU slots with similar filaments.

I’ve already tried:

• The built-in Overture PLA profile in PrusaSlicer
• The Overture PLA profile downloaded from their site (originally for MK3—adapted to MK4S)
• A wide range of adjustments in the Filament tab including temperature (195–215°C), retraction length/speed, deretraction, wiping, and cooling behavior

Despite this, I’m still getting:

• Stringing, especially between vertical features
• Zits on the backside and around thin parts surface
• Fuzziness on detailed areas
• Occasional “web walls” from consistent oozing between structures

If anyone has dialed in Overture matte PLA settings for the MK4S/MMU3 I’d love to hear your suggestions.

Thanks in advance!
