BFPTouch a Poor's man Remix

thingiverse

I understand that you may not need to spend much on a clone BLTouch, but the primary purpose of this project is for learning. Throughout the entire process, you'll gain a deeper understanding of how to set up a BLTouch in the Marlin firmware. Plus, this little DIY equipment is surprisingly accurate! I have several electrical components lying around, and I just wanted to put them to good use. You can watch my YouTube video to see the entire journey. Thank you, everyone!https://youtu.be/3aU_8-kGBhAA complete guide to confugirate a BFPtouchIf you use Platformio to customize marlin firmwarePlatformio.ini//replace mega2560 with STM32F103RET6_crealitydefault_envs = STM32F103RET6_crealityBFPTouch Marlin 2.0.9.7 settingsIn Configuration.h search for below values and uncomment/update where required.
