Items You Will Require Infrared Sensor - Https://Miscsolutions.Wordpress.Com/Mini-Height-Sensor-Board/ 3 Wire Servo Extension Lead (2 X 1M In Length) Files Included Mount Stl Front Cover To Do This Modification You Will Need To Update The Main Board'S Firmware. You Will Need To Update Using The Arduino Ide Software. There Are Plenty Of Youtube Videos Showing You How To Do This, Just Search For Update Marlin Via Arduino Ide. You Will Need To Open Your Machine Up And Feed The 3 Wire Connector Around The Machine. The Sensor Uses The Z Minimum Endstop Connector, So Just Unplug The Current One. The Current Z Endstop Needs To Be Removed. Just Unscrew It From The Side Frame And Hide It Below. You Can Always Go Back Then If Needed. I'Ve Already Configured The Firmware To Use This Sensor, So You Will Only Need To Flash It. I Have Enabled The Eeprom On The Board, So You Can Save Bed Levels.. But I Would Level At The Start Of Every Print Just To Be Safe. To Level, You Will Need To Add Some Gcode Lines To Your Start Gcode Script. There Is Normally A Tab / Section In Your Software.. The Lines You Need To Add Are, Add These After The G28 (Home) Command. M851 Z-1.0 ; Z Offset M500 ; Save To Eeprom G28 ; Home G29 ; Level Bed Etc... The Z Offset Can Be Set Above. Z-1.0 = 1Mm.. So If You Want To Lower The Head Then You Would Do.. M851 Z-1.2 ; Z Offset This Would Then Be 0.2Mm Closer Than Before. You Don'T Need To Change The Tft Firmware, You Won'T Get Any Benefit From It As It Doesn'T Support Z Offset Setting The Cover, Just Slides Down Onto The Mount :-) It Didn'T Look Very Nice Without It.
