Robo 3d Auto Bed Leveling (Auto Bed Height Compensation)
thingiverse
This video demonstrates the Marlin Auto Bed Leveling feature on a Robo 3D printer, which can be adapted for other printers. This function, better known as Auto Bed Height Compensation, greatly enhances the printer's performance, thanks to Marlin's developers. The printer now maintains consistent extruder height above the bed and allows easy adjustments via the LCD controller. Key components needed for the Z Probe include a printed frame, opto endstop, servo (e.g., SG90), printed horn, brass rod, and a probe set screw collar. The Z Probe connects to RAMPS board, with specific instructions available on GitHub. To enable Auto bed Leveling in Marlin RAMPS, follow the steps provided. The crucial parameter is Z_PROBE_OFFSET_FROM_EXTRUDER, adjustable by printing and testing. Servo angles for the Z Probe are typically 45 and 85 degrees but may vary. A printable servo horn may need filing to fit properly. Note that this setup removes the Z Min Limit switch and homing function. Add gcode commands at the start of the print file for bed probing and X/Y axis homing. Enjoy the convenience of automatic bed leveling and extruder height adjustment.
