DIY TOUCH-MI , wireless autolevelling Z-probe.Wireless part can be adapted to BLTouch and inductive sensors

I despise dealing with unnecessary wires.The other sensors require 3-6 additional wires to connect to the ramps/MKS board.An inductive sensor is heavy and its cable is big and heavy too.So in order to avoid that I designed a DIY Touch-MI Z-probe for auto-leveling a 3D printer without any wires.Description: The signal from an optic probe(DIY touch-Mi) is sent wirelessly via an infrared light (IR diode) to an infrared sensor connected to a 3D Marlin board on the z-end switch connector.The power for Z-probe and IR led comes from the 12V power supply of the hotend fan.Materials: - Optical endstop switch.https://www.ebay.com/itm/Optical-Endstop-Durable-RAMPS-1-4-Board-End-Stop-Switch-For-3D-Printer-CNC/264371544080?_trkparms=aid%3D555018%26algo%3DPL.SIM%26ao%3D1%26asc%3D20190212102350%26meid%3D183188f7aeae4c2b9d0b626a4f047fd1%26pid%3D100012%26rk%3D8%26sr%3D1679245%26tmp%3D1666%26trkparms=aid%25255355018%2526algo%25253Dsim.alexa%2526asc%25253190212102350%2526meid%25251833188f7aeae4c2b9d0b626a4f047fd1%2526pid%2525130012%2526rk%25238%2526sr%25311679245%2526tmp%25231666%26trknxt=m2%257C0.00%7C0%257C1666%257COrg:113%254011340%257Csrc:anchor%257Cr3:content%257Ckw:%252BOptical-Endstop-Durable-RAMPS-1-4-Board-End-Stop-Switch-For-3D-Printer-CNC - An inductive sensor is heavy and its cable is big and heavy too.So in order to avoid that I designed a DIY Touch-MI Z-probe for auto-leveling a 3D printer without any wires.Description: The signal from an optic probe(DIY touch-Mi) is sent wirelessly via an infrared light (IR diode) to an infrared sensor connected to a 3D Marlin board on the z-end switch connector.The power for Z-probe and IR led comes from the 12V power supply of the hotend fan.Materials: - Optical endstop switch.https://www.ebay.com/itm/Optical-Endstop-Durable-RAMPS-1-4-Board-End-Stop-Switch-For-3D-Printer-CNC/264371544080?_trkparms=aid%3D555018%26algo%3DPL.SIM%26ao%3D1%26asc%3D20190212102350%26meid%3D183188f7aeae4c2b9d0b626a4f047fd1%26pid%3D100012%26rk%3D8%26sr%3D1679245%26tmp%3D1666%26trkparms=aid%25255355018%2526algo%253Dsim.alexa%2526asc%25253190212102350%2526meid%25251833188f7aeae4c2b9d0b626a4f047fd1%2526pid%2525130012%2526rk%25238%2526sr%25311679245%2526tmp%25231666%26trknxt=m2%257C0.00%7C0%257C1666%257COrg:113%254011340%257Csrc:anchor%257Cr3:content%257Ckw:%252BOptical-Endstop-Durable-RAMPS-1-4-Board-End-Stop-Switch-For-3D-Printer-CNC - An inductive sensor is heavy and its cable is big and heavy too.So in order to avoid that I designed a DIY Touch-MI Z-probe for auto-leveling a 3D printer without any wires.Description: The signal from an optic probe(DIY touch-Mi) is sent wirelessly via an infrared light (IR diode) to an infrared sensor connected to a 3D Marlin board on the z-end switch connector.The power for Z-probe and IR led comes from the 12V power supply of the hotend fan.Materials: - Optical endstop switch.https://www.ebay.com/itm/Optical-Endstop-Durable-RAMPS-1-4-Board-End-Stop-Switch-For-3D-Printer-CNC/264371544080?_trkparms=aid%3D555018%26algo%3DPL.SIM%26ao%3D1%26asc%3D20190212102350%26meid%3D183188f7aeae4c2b9d0b626a4f047fd1%26pid%3D100012%26rk%3D8%26sr%3D1679245%26tmp%3D1666%26trkparms=aid%25255355018%2526algo%253Dsim.alexa%2526asc%25253190212102350%2526meid%25251833188f7aeae4c2b9d0b626a4f047fd1%2526pid%2525130012%26
