Automatic bed leveling probe foldable

thingiverse

March 5, 2014 update: Johann designed a new calibration concept that is better than the previous one as it doesn't require mechanical parts. Check it out here: http://reprap.org/wiki/FSR and https://groups.google.com/forum/#!topic/deltabot/6fxnM20nYKc. Introducing my automatic bed leveling probe for the Kossel, which is also compatible with the Rostock Printer using Johann's firmware. For more information on auto-leveling: http://reprap.org/wiki/Kossel; and about my leveling probe: http://6brueder.wordpress.com/2013/10/20/klapptaster-vorteile/. Here's a video demonstrating the functionality of the probe: http://www.youtube.com/watch?v=eXu27z3Sgg4. As for improvements, now the probe supports 10mm longer hotends (9-12-13). For those using a microswitch, I suggest utilizing M3 screws instead of M2.3-. Find my added functions in Johann's firmware for deploying and retracting the z-probe below: ```javascript void deploy_z_probe() { feedrate = homing_feedrate[X_AXIS]; destination[X_AXIS] = 30; destination[Y_AXIS] = 75; destination[Z_AXIS] = 40; // Adjusted to 40 for Kossel prepare_move_raw(); feedrate = homing_feedrate[X_AXIS]/10; destination[X_AXIS] = -10; prepare_move_raw(); st_synchronize(); } void retract_z_probe() { feedrate = homing_feedrate[X_AXIS]; destination[Z_AXIS] = 40; prepare_move_raw(); feedrate = homing_feedrate[X_AXIS]; destination[X_AXIS] = -35; destination[Y_AXIS] = 75; destination[Z_AXIS] = 40; prepare_move_raw(); feedrate = homing_feedrate[X_AXIS]/10; destination[X_AXIS] = 12; //destination[Y_AXIS] = 82; //destination[Z_AXIS] = current_position[Z_AXIS] + 30; prepare_move_raw(); feedrate = homing_feedrate[X_AXIS]/2; destination[X_AXIS] = 0; destination[Y_AXIS] = 0; destination[Z_AXIS] = 40; prepare_move_raw(); // Move the nozzle below the print surface to push the probe up. //feedrate = homing_feedrate[Z_AXIS]/10; //destination[Z_AXIS] = current_position[Z_AXIS] - 14; //prepare_move_raw(); //feedrate = homing_feedrate[Z_AXIS]; //destination[Z_AXIS] = current_position[Z_AXIS] + 30; //prepare_move_raw(); st_synchronize(); } ```
