Setting up probe Z & auto leveling function for my kossel mini

  In the endstop configuration you disable all min endstops and the pins. 

  
  

  In the Z-Probe configuration you use Z_min for Z-Probe Pin. 

  
  

  If it's a mechanical, normally closed "endstop" you are using for a probe, then you also need to Enable Pullup Resistor and Probe Trigger on High. 

  
  

  You also need to Enable Z-Correction and use a fairly small (60mm) correction radius. This is to use G29. 

  
  

  You should set your "Probe Height" to a reasonable number. Default is 40mm which will be way off. Usual probe heights are 1-5mm. Put in reasonable probe points: X0Y60, X-30Y-60, X30Y-60.

  
  

  Finally, I upped my speed a little on the probing z speed. Default is 2, I use 5. You may also want to increase probing repetitions to 2 or 3 if you want a little more accurate probing.

  Thanks for your reply UniversalRemonster!

  U mension "In the Z-Probe configuration you use Z_min for Z-Probe Pin. "

  This is what i want to know!

  Between when i type G29, there was no reaction!

  Below is my config.h

  // #################### Z-Probing #####################

  Well, there's a lot wrong with this configuration.h. First Z-Probe is disabled haha. Below, in red, are the correct settings you should use.

  I followed what u told me to update the config.h, but the probe Z crash on the glass, seems not working!

  Will that be endstop setting problem?

  Thanks UniversalRemonster ! The probe Z is working now, but i notice one more problem was the XY locaiton for auto level was not what i want?  But i check with the panel face moving the nozzle around and the XY location is OK!

  Check eeprom. You have the positions stored there and they get taken from there.

  I am having trouble understanding you. What do you mean xy location for auto level is incorrect? Does the nozzle try to move outside of your printer? 

  
  

  The locations should be: 

  
  

  #define Z_PROBE_X1 0
  #define Z_PROBE_Y1 -60
  #define Z_PROBE_X2 -30
  #define Z_PROBE_Y2 -60
  #define Z_PROBE_X3 30
  #define Z_PROBE_Y3 -60
  

  
  

  Are you using G29 or G32? They are different. G29 is for bed bumb mapping/z-height correct. G32 is used for autoleveling.
