3D Touch Sensor Auto Bed Leveling Sensor BL Touch BLTouch 3d printer parts …

Overview:The 3DTouch auto leveling sensor is a device that uses the Hall effect to achieve leveling. The position of the point can be obtained by touching the point on the heated bed, and then compensated by adjusting the z-axis height during printing. Printing can also be achieved even though the platform is not flat.Parameter:Voltage5VCurrent15mAMax current(peak)300mAShell materialPCShell colorWhiteCable lengthShort: 200mm Long: 1000mmWire3pin: Green: -GND Red: 5V Orange: Signal cable 2pin: Black: -,GND White: ZminMarlin Settings:Marlin settings( take Marlin V1.1.X as example ) 3pin cable connects to D11, 2pin cable connects to Zmin.(1) Set leveling pin, which can’t use the same pin as endstop. Generally, on Delat machines, we use Zmin pin for BLtouch, Zmax pin for endstop. On I3 machines, we use Zmin pin as BLtouch, Zmax pin for endstop or don’t use endstop.(2) Set leveling type(3) Enable Z_MIN_PROBE_USES_Z_MIN_ENDSTOP_PIN(4) Enable BLtouch(5) Set the offest value of the leveling switch probe from the nozzle in the XYZ direction(6) Set leveling mode(7) Set leveling points number(8) Set homing center(9) Store the leveling settings 1) Remove “//” before the “#defing EEPROM_SETTINGS”, start M500 to store the data.2) Open Marlin_main.cpp, find “case 28: // G28: Home all axes, one at a time gcode_G28(false);”, add this sentence: “set_bed_leveling_enabled(true);” It’s important to add this sentence, otherwise the leveling data can’t be stored.(10) Remove “//” before the #”define NUM_SERVOS 3″
