Longer LK5 Pro FDM Printer BL Touch Tutorials, Make You Print More Easy.

BLTouch is an auto leveling sensor for 3D Printers that can precisely measure the tilt of Bed surface. It could work with any kinds of bed materials, such as glasses, woods, metals, and so on. Follow this video, install BL-touch in your Longer Lk5 Pro, make you print more easy, save your time in future print. also we have article version about this tutorials, Article Tutorias with photo, in official webpage: https://bit.ly/3eaTene . hope you like. Longer Facebook:   / longer3dprinter   Longer Instagram:   / longer3dprinter   What we should do with BL Touch install: Auto Leveling Sensor User Manual Preparation • LONGER FDM Printer LK or LK Pro series • BL-TOUCH, 3D-TOUCH or other similar sensor • Sensor attached wires(5 pin) • Sensor attached screws and nuts(2 pairs) • Sensor mount(printed .stl model) • USB cable • Pronterface or other serial port communication software • 50k ohm or 100k ohm resistor(LKx series users only) Wiring 1. Switch-off the printer power 2. Find the position of motherboard, then screw down the mother board cover. 3. Unplug the Z-MIN wire(2 pin) in board 4. Hook up the sensor and the motherboard. LKx series users need parallel a 50 or 100 k ohm resistor between 5V pin and PWM pin as the picture showing below 5. Screw up the mother board cover LKx Pro series board wiring LKx series board wiring need extra resistor Mounting 1. Remove the Z axis end stop switch as picture showing below Remove the z min end stop switch 2. Screw down left 2 screws of head module 3. Mount BL-TOUCH as picture showing below Mount sensor Power on 1. Confirm BL-TOUCH wiring and mounting is complete 2. Switch on the printer power 3. Connect PC and printer with USB-cable 4. Flash BL-TOUCH dedicated firmware. check the firmware update manual if you need. 5. Open pronterface software, select serial port(115200 baudrate). and connect to printer Adjusting z-offset 1. Clean up bed and nozzle, and ensure no materials stick on them. 1. Send G28 to homing XYZ axis. 2. Send M851 Z0 to reset Z offset value. 3. Send M500 to save current. 4. Send M501 load all saved settings from EEPROM. 5. Send M503 print a concise report of all current settings (in SRAM) to the host console. 6. Send G1 F60 Z0 to lower Z axis to the software origin. 7. Send M211 S0 to inactivate software endstop function. 8. Placea sheet of paper (or other block of 10mm approximately) on the bed and use the pronterface to lower the nozzle 1mm by 1mm then 0.1mm by 0.1mm until you feel a friction on the sheet of paper (the paper is not to be jammed but not too free either). Then remove the sheet. 9. Send M114 to get current Z height value(usually negative). the value is the z-offset we 10. Send M851 Z x.x to set z-offset(x.x is the value of previous value) 11. Send M500 to save current. 12. Send M501 load all saved settings from EEPROM. 13. Send M503 print a concise report of all current settings (in SRAM) to the host console. 14. Send M211 S1 to re-activate software endstop function 15. Send G28 Z0 to home Z axis 16. Send G1 F60 Z0 to test if Z axis could back to the actual Z origin by checking the clearance between bed and nozzle if is about 1 mm (thickness of a sheet of paper). If not, please repeat step 1 to 16. Activating auto leveling 17. Send G28 to homing XYZ axis 18. Send G29, and waiting for bed tilt measurement to complete 19. Send M500 to save measurement values of previous step. 20. Send M501 load all saved settings from EEPROM. 21. Send M503 print a concise report of all current settings (in SRAM) to the host console. 22. Send M420 S1 to activate auto leveling function Replace GCODE 1, Replacewith new START GCODE(in appendix section) in your slicer software(Cura, Slic3r, Simplify3D, ) 2, Have fun! :) Appendix -- BL-TOUCH START GCODE -- G21 ; metric values G90 ; absolute positioning M82 ; set extruder to absolute mode M107 ; start with the fan off ; confirm BL-touch safety M280 P0 S160 ; BL-Touch Alarm release G4 P100 ; Delay for BL-Touch homing G28 X0 Y0 ; move X/Y to min endstops G28 Z0 ; move Z to min endstops ; reconfirm BL-touch safety M280 P0 S160 ; BL-Touch Alarm realease G4 P100 ; Delay for BL-Touch ; bed leveling G29; Auto leveling M420 Z5 ; set LEVELING_FADE_HEIGHT M500 ; save data of G29 and M420 M420 S1 ; enable bed leveling ; prepare hot-end G92 E0 ; zero the extruded length G1 F200 E3 ; extrude 3mm of feed stock G92 E0 ; zero the extruded length again M117 Printing ; -- end of BL-TOUCH START GCODE -- Files Download: PC Software: https://drive.google.com/file/d/1Dudx...
