LK4 Direct Drive Modification
thingiverse
To print flexible filament effectively, direct drive mode must be enabled by modifying LK4 to bypass the stock gearing. The added weight of the modification does not compromise print quality. Following the modification, adjust your retraction value to 1.2mm for optimal results. This setup now works seamlessly with Flex98A filament, whereas 95A remains too soft for this specific configuration. Enjoy printing!
