Automatic bed leveling probe foldable

thingiverse

Update March 5, 2014 Johann designed a new concept to calibrate. I think its better than this one, because it doesn't needs mechanical parts.http://reprap.org/wiki/FSRhttps://groups.google.com/forum/#!topic/deltabot/6fxnM20nYKc This is my Automatic bed leveling probe for my new Kossel. It works at the Kossel and also at the Rostock-Printer with the Firmware from Johann. More Information about Autoleveling:http://reprap.org/wiki/Kossel More Information about my Leveling-Probe:http://6brueder.wordpress.com/2013/10/20/klapptaster-vorteile/ A video about the functionallity:http://www.youtube.com/watch?v=eXu27z3Sgg4 9-12-13 Now also for 10mm longer Hotends. Instructions -For the microswitch i use M3 screws instead of the M2.3- -This are my functions in the Firmware from Johann for deploy and retract the z-probe. void deploy_z_probe() { feedrate = homing_feedrate[X_AXIS]; destination[X_AXIS] = 30; destination[Y_AXIS] = 75; destination[Z_AXIS] = 40; //NB vorher 100 für Kosselumbau reduziert 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(); }
