#Please see the newer version [Here](https://www.thingiverse.com/thing:2766701) It features a much better design with more compatibility and better cooling! Updated 1-18-18 READY TO GO! See it run here: https://youtu.be/Nrn9100MQbY See my Rear Sensor Mount version here https://www.thingiverse.com/thing:2763157 All instructions are for the Anet A8. Reduced some sizes, moved some things and cleaned it up. I added some zip tie holes in the sides and improved tolerances. I made slotted holes because my printed X mounts changed the dimensions a bit. I have printed, installed and now used this part. Below are instructions on how to set it up. I printed them with 1.8mm wall and 30% fill. I also made a set at 1.2mm wall and 15% fill that worked perfectly. Both in PLA. This includes guides like my thing https://www.thingiverse.com/thing:2732685 built into the mount. Get the latest Skynet3D firmware from https://github.com/thijsk/Skynet3d and please update your firmware as follows: Enable RAMPS boards, this is for the common ones like https://goo.gl/XW91zh [Amazon.com link] PLEASE pay attention and be sure to choose the correct code for your motherboards. See boards.h in the Skynet firmware for a list. define MOTHERBOARD BOARD_RAMPS_14_EEB Enable dual extruders: define EXTRUDERS 2 Offsets for the extruders: define HOTEND_OFFSET_X {0.0, 35.00} define HOTEND_OFFSET_Y {0.0, 0.00} For the probe it's : define X_PROBE_OFFSET_FROM_EXTRUDER -35 // X offset: -left +right [of the nozzle] define Y_PROBE_OFFSET_FROM_EXTRUDER 4 // Y offset: -front +behind [the nozzle] define Z_PROBE_OFFSET_FROM_EXTRUDER -0.5 // Z offset: -below +above [the nozzle Set this to your machine. I used a .5mm thick print put between the bed and probe with the nozzle touching the bed to start.] You also need to set travel limits: // Travel limits after homing (units are in mm) define X_MAX_POS 240 define X_MIN_POS -15 define Y_MAX_POS 230 define Y_MIN_POS -13 define Z_MAX_POS 230 define Z_MIN_POS 0 And probe point offsets: // Set the boundaries for probing (where the probe can reach). define LEFT_PROBE_BED_POSITION 27 define RIGHT_PROBE_BED_POSITION 200 define BACK_PROBE_BED_POSITION 200 define FRONT_PROBE_BED_POSITION 20 See https://goo.gl/NkkGsb [3D print wiki] for the best instructions I have found so far on how to set your probe Z offset. I did this using the terminal in Octoprint via to Raspberry Pi on the printer. I am running RAMPS 1.4 with Skynet firmware. Anyways, this is getting out of hand so here's the important stuff: Many models to choose from! - No sensor mount - 18mm sensor - 12mm sensor - 8mm sensor Then choose you cap: - 2 stock fans with chain mount - 2 stock fans no chain mount - No fans no chain mount - No fans with chain mount - if you need them there's fan spacers too. I found my duct hit the extruder. If you go with one with a chain mount I have included the X axis chain links from https://www.thingiverse.com/thing:2193695 This is what I remixed from. You may get the other end mount from here or use mine at https://www.thingiverse.com/thing:2762145 Then choose you print settings: - Choose .AMF or .STL. I found .AMF more accurate and works in Cura. - Made one at .4mm Nozzle, .2mm step, 1.6mm wall and 30% fill worked great - Made a second at .4mm nozzle, .2mm step, 1.2mm wall and 15% fill, worked just as good. - Do your own of course! You guys know what's what. You will need: 1) E3D style extruders 2) RAMPS 1.4 or 1.5 3) Marlin/Skynet firmware 4) 40mm M4 Screws and Nuts for the cap, 3 of them 5) 50mm blower fan 6) Wires, connectors, crimpers, and a soldering iron helps. I have made a guide in PDF form available here https://goo.gl/1s8jSR for setting the offsets. You will need a serial connection to your printer and I found using Octoprint is really easy. Here's a crapCAD schematic of the optocoupler board I made to run the 12v probe completely isolated from the RAMPS board.  Thank you! Enjoy and please like, comment and share!
