Flsun3d auto bed leveling arm

Mine probe is: LJ12A3-4-Z/BX - 22mm mounting probe with 4mm distance detection. First prints worked fine. Still some fine tuning needed. If you are using standard given firmware you need to change following lines: 282 - check your polarisation of your probe: NPN - true; PNP - false; const bool Z_MIN_ENDSTOP_INVERTING = true; 335 - uncomment define ENABLE_AUTO_BED_LEVELING 384 - offset only on x axis: 38.78 define X_PROBE_OFFSET_FROM_EXTRUDER 38.78 define Y_PROBE_OFFSET_FROM_EXTRUDER 0 define Z_PROBE_OFFSET_FROM_EXTRUDER 0 Known problems in firmware: Marlin_main.cpp line 995 - just add brackets to values do_blocking_move_to((x - X_PROBE_OFFSET_FROM_EXTRUDER), (y - Y_PROBE_OFFSET_FROM_EXTRUDER), current_position[Z_AXIS]); Print Settings Printer: FLsun3d Rafts: No Supports: No Resolution: 0.2 Infill: 85 Notes: Adding two versions - with a round handle and square handle for the probe Post-Printing for post print you need to drill out holes for screws using 3mm metal drill bit (at least I needed to do it)
