Flsun3d auto bed leveling arm

thingiverse

My probe is LJ12A3-4-Z/BX, a 22mm mounting probe with 4mm distance detection. First prints worked well. However, some fine tuning remains necessary. If you're using the standard firmware provided, you'll need to modify the following lines: 282 - Check your probe's polarization: NPN is true; PNP is false; const bool Z_MIN_ENDSTOP_INVERTING = true; 335 - Uncomment #define ENABLE_AUTO_BED_LEVELING 384 - Adjust only on the 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 Firmware issues include: Marlin_main.cpp line 995 - 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 - one with a round handle and another with a square handle for the probe. For post-printing, you'll need to drill out holes for screws using a 3mm metal drill bit (at least I had to do it).
