Anet A8 X Axis Lead Screw Drive System

thingiverse

You can see my Anet AM8 Y Axis Lead Screw Drive System here. This is based off Leo_N's awesome Anet A8's X-Carriage Mounts. The first home of the machine is here. First Print Start is here, and First Print Next Layers are here too. Second print with TMC2208 and new settings can be seen here, and Second Print Second Layer is here as well. See it in action! With the Y axis too, here's a video for you to check out. #BOM: - 400mm long 8mm 4 start lead screw with Anti-Backlash nut is available on Amazon. You'll also need Couplers, which can be found here. 688-2RS-BU Bearings x 2 are required, and Locking Collars can be purchased here too. BTT S42B Closed Loop Control is the final item you'll need. #Installation Notes! I printed these in PLA with 20% infill. The closed loop is crucial for this to work properly. You can learn more about it on the 3DLS website. #I am releasing this into the wild! #Got an idea? Post it as a comment! #Thank you! - Update 11/29/19 First update, changed the bearing holders for increased clearance. All files reloaded. - Update 12/1/19 Printed the parts, ran into an issue. I couldn't find small enough lock collars. The ones listed work. You really only need one on the motor side. Use the spacer to press against the bearing and collar locking the screw back against the motor. The screw must be locked to prevent it from moving instead of the carriage. - Update 12/3/19 It's installed! Working out the firmware and system tweaks now. There's about to be a huge update! - Update 12/6/19 Released! All files updated to final versions. See description above for firmware setup notes. - Update 12/7/19 I found the nut on the carriage part hits the side frame when it homes so I switched it to the other side. Carriage Part updated. - Update 12/8/19 Updated the Right Side. Made the holes for the smooth rods deeper by 3.5mm for a little wiggle room. - Update 12/12/19 Updated design for more strength and easier assembly. Now it has separate rod caps so the rods can be slid in and out. Motor mount greatly reinforced.
