Tiny-Touch NMPG

# Tiny-Touch NMPG This is a remix of my [Tiny-Touch](https://www.thingiverse.com/thing:3833861) (but Thingiverse won't let me publish a Remix for some reason). The NMPG appendix stands for "**N**o **M**agnets, **P**ure **G**ravity" ;o) In order to achieve this, you have to print the parts with a layer height of 0.1 mm (or less). Changes compared to [V1](https://www.thingiverse.com/thing:3833861): - needs no magnets - slimmer body / flag - slotted mounting holes - IR sensor cap added (optional) Wiring is the same as in V1. # BOM: Same as for [V1](https://www.thingiverse.com/thing:3833861) except you need no magnets, one additional 2.2 x 6.5 self tapping screw for the IR sensor cap and the M3 bolt has to be 25 mm in length. # Modders welcome The STEP file is included for those who need to add a custom mount. Therefore, the upper part of the mount is separated in the STEP file and it also contains some variations. # Setting up Tiny-Touch for Marlin If you want to set up Tiny-Touch on Marlin (2.x), don't use the BLTouch definitions! Here's a [really nice how-to](https://www.reddit.com/r/ender3v2/comments/nxm865/guide_for_bfptouch_on_ender_3_v2/) on reddit made by user **cpxazn**. The how-to originally describes the [BFP-Touch](https://www.thingiverse.com/thing:2890290) sensor but it's the same as for Tiny-Touch. Skip the hardware section and go directly to the **Firmware** section of this write-up. The only difference in the setup is the definition of the servo angles for deploying / retracting the probe. For the BFP-Touch these values are: ```C #define Z_SERVO_ANGLES { 100, 155 } ``` Whereas for the Tiny-Touch you'll need: ```C #define Z_SERVO_ANGLES { 170, 20 } ``` Please follow the instructions step by step to the end and you'll be successful.
