Anet A8 Rear Sensor Mount for TronXY Style Sensor w/ Height Screw STOCK EXTRUDER

thingiverse

***UPDATE 09/07/17*** I've revamped the design - it's now even more stable and only requires a few screws - I'm also quite confident that it can work with the E3D carriage! I've uploaded it as a Remix as the V2, instead of replacing this Thing for comparison's sake. <a href="https://www.thingiverse.com/thing:2426460">View the new mount here!</a> ***UPDATE 30/06/17*** I decided to make some tweaks and created "sensorMountC" which combines the best features of both the original and "sensorMountB". It uses the alignment block and has large flaps on top. I actually printed this one as the original twisted too much for my liking, so it should be much more stable. So, yeah - I recommend printing that one instead. (I also leveled the bed properly this time, which helped with the print quality) NOTE: The photos are of a test version - I made some minor improvements since they were printed. I've marked this as a WIP while I add a few photos/diagrams to the instructions and replace the blurry ones. Hopefully there should be enough written information and pictures to get you started. I'm using a lot of screenshots from Blender for now, which helps show the part layout better and isn't as blurry as my photos. With that out of the way... I bought myself an affordable autolevel sensor from GearBest for my Anet A8 (The "<a target="_blank" href="http://www.gearbest.com/3d-printer-parts/pp_591321.html?lkid=10919950" title="Gearbest Practical 6 - 36V Auto Leveling Sensor for 3D Printer">Practical 6 - 36V Auto Leveling Sensor for 3D Printer</a>", it arrived marked as a TronXY sensor), but the mount wasn't going to work with the E3D mount I printed, so I designed this rear mount with a screw for precision height adjustment in Blender. Advantages of this include: * Much lighter than the acrylic hunk that comes with the sensor * Sensor height can be adjusted with much higher precision using a screw and spring * Sensor is out of the way of the nozzle, allowing a good view of prints * Does not displace the fan at all, so you don't have to worry about whether your duct is in the right position * It's compatible with most other custom X-carriages as it doesn't mount directly to them What you need: * A 3D printer to print all these bits out * A small spring - I got one from a worn out pen * The M3 nuts and screws that come with the sensor * Another M3 nut (for mounting the "sensorBlock") * 4 M3*12 screws (usually leftover from the printer - I was one short, so I just used some spare tiny M2 screws for the "alignmentBlock", and it's holding fine) * A screwdriver to tighten everything up * A pretty long M3 screw (I used M3*30, but think you should be able to use an M3*20) You only need to print one of each part. Information about these in Post-Printing. To use the sensor with the Anet A8, I had to switch the brown and blue wires, such that the order was BLACK BROWN BLUE instead of BLACK BLUE BROWN. I found this out from to the <a href="https://www.youtube.com/channel/UC2Tc0TsvFxC83zF1w5x1PWQ?&ab_channel=3DMakerNoob" target="_blank">3D Maker Noob</a>, but thought it was worth noting here too. As a little side note, the sensor is inductive, not optical. I'd seen it asked on the store page, so I gave it a test to find out. I'm pretty new to 3D printing and this is my first uploaded Thing, so if you have any tips, I'd love to hear them! "sensorBlockB" is an experimental model that I've made, but not printed or tested. The idea is that it doesn't need the "alignmentBlock", though it could be more wobbly going forward and back. If you print it and it works, it would be great to see!
