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

Stephen

I just built a Kossel mini using radds board, the max end stop doing good. Just wonder how to setup the probe Z with min Z end stop?Do I need to set up the min Z end stop (pin no.) when downloading the repeiter firmware or modified the cong.h file after download?Please help!

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 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!

Repetier

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.
