Hi,
i am trying to set up my (mechanically modified) Kossel with Marlin 2.1.2
Below are my Delta settings, Radius is correct.dd
// Enable for DELTA kinematics and configure below
#define DELTA
#if ENABLED(DELTA)
// Make delta curves from many straight lines (linear interpolation).
// This is a trade-off between visible corners (not enough segments)
// and processor overload (too many expensive sqrt calls).
#define DEFAULT_SEGMENTS_PER_SECOND 200
// After homing move down to a height where XY movement is unconstrained
//#define DELTA_HOME_TO_SAFE_ZONE
// Delta calibration menu
// Add three-point calibration to the MarlinUI menu.
// See [minow.blogspot.com]
#define DELTA_CALIBRATION_MENU
// G33 Delta Auto-Calibration. Enable EEPROM_SETTINGS to store results.
#define DELTA_AUTO_CALIBRATION
#if ENABLED(DELTA_AUTO_CALIBRATION)
// Default number of probe points : n*n (1 -> 7)
#define DELTA_CALIBRATION_DEFAULT_POINTS 3
#endif
#if EITHER(DELTA_AUTO_CALIBRATION, DELTA_CALIBRATION_MENU)
// Step size for paper-test probing
#define PROBE_MANUALLY_STEP 0.05 // (mm)
#endif
// Print surface diameter/2 minus unreachable space (avoid collisions with vertical towers).
#define DELTA_PRINTABLE_RADIUS 100 // (mm)
// Maximum reachable area
#define DELTA_MAX_RADIUS 102.5 // (mm)
// Center-to-center distance of the holes in the diagonal push rods.
#define DELTA_DIAGONAL_ROD 217.5 // (mm)
// Distance between bed and nozzle Z home position
#define DELTA_HEIGHT 247.8 // (mm) Get this value from G33 auto calibrate
#define DELTA_ENDSTOP_ADJ { 0.0, 0.0, 0.0 } // Get these values from G33 auto calibrate
// Horizontal distance bridged by diagonal push rods when effector is centered.
#define DELTA_RADIUS 147 // (mm) Get this value from G33 auto calibrate
// Trim adjustments for individual towers
// tower angle corrections for X and Y tower / rotate XYZ so Z tower angle = 0
// measured in degrees anticlockwise looking from above the printer
#define DELTA_TOWER_ANGLE_TRIM { 0.0, 0.0, 0.0 } // Get these values from G33 auto calibrate
// Delta radius and diagonal rod adjustments (mm)
//#define DELTA_RADIUS_TRIM_TOWER { 0.0, 0.0, 0.0 }
//#define DELTA_DIAGONAL_ROD_TRIM_TOWER { 0.0, 0.0, 0.0 }
#endif
At Autocalibrate, the printer probes 4 Points at the center of the build plate, then 1 point near the X-Tower, then it goes out of the bed and gets stuck. I have to power down the Mega2650 to be able to home the printer.
What could cause that? I can't find any other parameters for probing.
Thank You,
Adrian
