# Wanhao I3 Duplicator BLTouch Bracket # Summary When I was upgrading my Wanhao Duplicator I3, I looked into adding bed levelling to the printer. To do this, I used the BLTouch unit and upgraded the Wanhaos firmware to incorporate this sensor. Doing this, I found that none of the Thingiverse BLTouch mounts fitted my specific printer due to the metal bracket being longer than the usual bracket. So I redesigned the frame and created the one shown above and below. # Marlin Firmware Probe Offsets ```C #define X_PROBE_OFFSET_FROM_EXTRUDER 52 // X offset: -left +right [of the nozzle] #define Y_PROBE_OFFSET_FROM_EXTRUDER -46 // Y offset: -front +behind [the nozzle] #define Z_PROBE_OFFSET_FROM_EXTRUDER -2.72 // Z offset: -below +above [the nozzle] ``` # Equipment List - [BLTouch Kit](https://www.amazon.co.uk/gp/product/B0748FJ48N/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1) - [Dupont Crimps](https://www.amazon.co.uk/gp/product/B07JBCKYPG/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1) - [Multithreaded cable](https://www.amazon.co.uk/gp/product/B07G72DRKC/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1) - No extra bolts are required; the original ones are fine - Bolts and Nuts come with the BLTouch for mounting on to the bracket # Useful Links - [BLTouch Guide](http://blog.osdev.org/3d/printing/2019/10/13/wanhao-duplicator-i3-bltouch.html) - [Wanhao i3 Duplicator V2](https://www.wanhao3dprinter.com/Unboxin/ShowArticle.asp?ArticleID=70) - [Marlin Firmware](https://github.com/MarlinFirmware/Marlin)
