PLR Klipper

YUMI_PLR for Klipper is a simple print recovery system for Klipper, a 3D printer firmware. It allows you to resume prints after a power loss or other types of MCU disconnection interruption. Please note there is no guarantee that it will work in 100% of cases because the Z-axis must not have moved, so do not touch the machine in case of a power cut.
