Model originally uploaded to Thingiverse at https://www.thingiverse.com/thing:4933189. **Description** ==================== This is a remix of TinyTouch NMPG, a very cost-efficent alternative to BLTouch and other commercial products - adapted for use on Ender 3/Ender 3 Pro with stock extruder assembly Please note that even though this is a really interesting project for a weekend ***it might be hard to reproduce*** - minimal soldering skills, basic knowledge about firmware configuration (or will to learn about these things for one+ evening ;]) and a decently calibrated printer are required (problems are inevitable really) You will need to tap M3 holes in body, flag and sensor cap, this will require good layer adhesion - but you can always try to re-melt plastic in holes using a screw and a solder iron in case something goes wrong (be careful about it tho!) Although mount is BLTouch-friendly, it's not fully compatible with it - if you decide to swap to BLTouch at some point you will likely need a spacer between device and mount (TT is slightly taller) **Instructions** ==================== For full instructions see [TT NMPG](https://www.thingiverse.com/thing:4661556) and [TT v1](https://www.thingiverse.com/thing:3833861) **Servo and sensor models** ==================== Compatible servos are [Mosquito R](https://www.graupner.com/micro-linear-servo-14001.html) and GS-1502 R (R stands for Right - this is ***important***, but you can also buy a pair of L and R and find use for Left one later) Key words for alternatives are: Micro Linear V-Tail Servo As for optical sensors, there are tons of compatible ones if you search for 3D Printer Endstop Optical Switch, just look for similar models (I used Aokin/HESAI branded one) Both items are easily sourced from Amazon/Aliexpress/etc. Note that this is not a full list of materials, see original thing's BOM - most importantly, don't forget about JST XH 4POS header! **Corrections and notes** ==================== Make sure to print flag using filament that doesn't allow much light to pass through! My first try had flag in yellow PLA and optical sensor was getting semi-triggered, but not enough for printer to detect anything Probe offset for parts provided in this remix is `X-43 Y-10` `#define NOZZLE_TO_PROBE_OFFSET { -43, -10, 0 }` Actual angles for me were the other way around, `#define Z_SERVO_ANGLES { 20, 170 }` And also we will have a bigger mesh inset compared to original guide `#define MESH_INSET 45` I personally use it with vanilla Marlin (no forks), you can mostly follow a [guide by *u/cpxazn*](https://www.reddit.com/r/ender3v2/comments/nxm865/guide_for_bfptouch_on_ender_3_v2/) mentioned in [TT NMPG](https://www.thingiverse.com/thing:4661556) instructions with corrections above in mind - but make sure to read all comments for parameters you change in config files, don't change anything blindly. And yes, you ***must not uncomment BLTouch define***
