Preset includes well-tuned parameters for MK3s(&MMU2s) with V6 and Revo hotend, especially I had handwritten specific gcode to reliably print flexible filament with MMU2s.
It also includes fast printing profiles, supports Modex PLA, SpiderMaker PLA, 2718 PLA, 2718 PETG, Modex TPU(75A), and SpiderMaker TPU(75A), as well as well-tuned LA1.5 factor and flowrate for these specific combinations.
