cults3d

Ender 3 V2 / V2 Neo linear shaft / LM8LUU mod. 10 minutes installation. The only downside - have to cut out like 20x10mm of the drawer front door so it can open fully. BOM - 2x 8mm 350-362mm rods, 4x LM8LUU, 8x M5x20mm screws, 8x T-nuts. Can reuse bolts / nuts from the original Y axis, but I would recommend to use standard nuts without plastic thread lock. If you use low temp plastic insulation may be needed. Carriages are in direct contact with the bed frame that may get hot. Lubricate LM8LUU - I use "Super Lube". - Insert LM8LUU into carriages. Insert 4x M5 nuts into carriages. Attach carriages to a bed frame but do not tighten bolts yet. Insert shafts into back supports - push them as much as you can so they are fully inserted. If you use 362mm shafts there is pretty tight tolerance. Install back supports with shafts already attached. Make leave small gap between motor an left back support - like 0.5mm Install bed frame with carriages on shafts Install front supports. Tighten all supports. Tighten left side bed frame screws. Move bed front and back and make sure that everything moves OK. Tighten right side bed frame bolts. Install bed and level it. Enjoy!
