Tronxy X5S Z binding releaser

<p>It is (nearly) always a bad idea bind both ends of the Lead Screw Rod .</p> <p>X5S has heavy duty bearing on the top end which has a couple additional issues. Typically bearing is not seated properly by it is tilted, requires a significant force to make it straight (note, apply the force only to the outer ring of the bearing).</p> <p>The second issue is the worm screws for locking the lead rod. Most probably the screws will bend the rod because the rod is uneven surface.</p> <p>The best solution is to allow the lead screw to flex via two pivot points - stepper motor coupling and lead screw nut of the bed.</p> <p>This part fix the side lead rods upper ends but for center lead screw it has 2mm over size hole allowing the flex.</p> <p>I include test print (50x50mm, single 0.4mm wall, layer mode). The bottom section 5mm is printed 60mm (100%) speed, then the speed is tuned up to 200% (+temp 30C) and the top section 300% (+temp 15C). (the original board is struggling to draw constant curve with 300% but straight sections went full speed. Part was places typical 90 angle)</p> Category: 3D Printer Parts
