CR-10 BTN Adjustable Z Stop

thingiverse

There are adjustable z stops on this setup for the CR-10, all but one don't have adjusters, so you loosen the screws while holding the plate and trust that you can move it point five millimeters then hold it tight while tightening the screws back up. Clearly, I'm not as coordinated as others because I couldn't manage it. So here's a "better than nothing" adjustable z stop for the CR-10. I use a three-millimeter by twenty-millimeter screw and two lock nuts. One goes in the little box to hold the screw in place, and the other goes on the bottom of the screw so it has a larger surface area to press against the base plate. You'll need to replace the M5 x 10 millimeter screw that holds the T frame support with an M5 x twelve millimeter screw to hold the base plate and the T frame support. I start by adjusting the screw to about the middle, so I can go up or down as needed. Then I tighten the M5 screws to hold it in place. After that, I do an auto-home and level the bed for that height. Next, I loosen the M5 screws a bit and make fine adjustments to the z stop by turning the three-millimeter screw and tightening the M5 screws back up if my extrusion flow isn't right without re-leveling the bed every time. I hope this works as well for you as it has for me.
