Software Setup
  1. Download the firmware and put your settings in the configuration.h
By default , double check the following settings for FSR auto leveling.
#define TEMP_SENSOR_BED 5                                                                    // Heatbed sensor for FSR
#define BED_MAXTEMP 1000                                                                       // Max value for Heatbed sensor (FSR)
#define ENABLE_AUTO_BED_LEVELING                                                     // Enable Auto Bed Leveling
#define DELTA_PROBABLE_RADIUS (DELTA_PRINTABLE_RADIUS*0.7)        // By default is 0.9 , but in my case , 0.9 will go outside or crash my glass clipper , so I set to 0.7
#define Z_PROBE_OFFSET_FROM_EXTRUDER 0.40                                   // Increase this if the first layer is too thin. Default is 0.1 , that is too thin for me , so I set to 0.4
 
  1. Complie the firmware and upload to the Mega 2560
