Longer LKL4 Prod Linear Rails (X-Y-Z), Dual Z Motor, Direct Drive
Description
All Started with this project: https://www.thingiverse.com/thing:4258451 Longer printers are pretty close to Creality as they use same opensource project, but all dimensions and some of the construction is different so I had to redesign everything from the ground up with the correct dimensions. I ended upgrading all Axis to linear rails MGN12, dual Z motor. In the process I also switched to Direct Drive with some parts I had from before (works with original hotend and extruder too) Assembly video will be available soon on Youtube. Attached is BOM for all the parts from Aliexpress. Included Z axis mounting blocks, right gantry assembly backplate both for single and dual motor (Longer do not use one), Y-axis endstop modification to go over rail for proper alignment. Modified tool for Z-Axis vertical alignment as my gantry sits higher - original here: https://www.thingiverse.com/thing:4320411 Source in Tinkercad if you need to modify something: https://www.tinkercad.com/things/4KNUP1LDrkR-longer-lk4-pro-z-linear-rails You will also need: Adjustable motor mount: https://www.thingiverse.com/thing:4723087 Linear rail 12mm alignment tool: https://www.printables.com/model/505053-2020-aluminum-profile-12mm-linear-rail-alignment-c Optional: Cable chain: https://www.thingiverse.com/thing:6651436 Drawer system: https://www.thingiverse.com/thing:3740067
