Mostly-printed Z-axis for Neje 30W/40W laser modules
prusaprinters
<p>This Mostly-printed Z-axis for Neje 30W/40W laser modules is a mashup/modification and remix of a couple of designs: Silvester's 3D-Printed CNC Z-axis for Nema17 (Pinshape) and leadscrew/nut from 3DPRINTINGWORLD's Linear Ball-Bearing Stepper Stage V2 (TV).</p> <p>While this version uses printed linear bearings and raw 5/16" drill rod, 8mm polished rod and LM8UU bearings can -- and should -- be used. Here the Z-axis is being exercised over a 50mm range and should be more than enough to bring the laser beam into perfect focus on various thickness materials. Assembled with a couple of 608 skate bearings, a couple of 125mm long 8mm (5/16") rod, and 3mm machine screws.</p> <p>The r3 frame is less the tab on the bottom end, and overall shorter, with extra mounting holes on 20mm centers to better fit my machine.</p> <p>Testing -- <a href="https://www.youtube.com/watch?v=qxikYlaJYwo">https://www.youtube.com/watch?v=qxikYlaJYwo</a></p> Category: Machine Tools
