I got the bed leveling running now. So many times of flashing and debugging and at the end it was just a simple number that was wrong in the firmware.
I try to explain
When you setup your probe you have to set the offset of the probe.
The location of my probe is X+33mm on the left side of the extruder and Y-10mm.
Then you have to write the probing positions of the bed like: 30mm left, 100mm right, 15mm front, 120mm back in the firmware.
My left position was not right and if I do a easy math 33mm(the position of the probe)-30mm (where I wanted a probe position)= -3mm.
This means the extruder want travel to x -3mm. That's why I had all the problems. I changed the wanted position to +40mm and now it work awesome.
Sorry if I make you all headaches, but my English is not the best and I want to write as easy as possible.
I don't no why you do not understand the principe of the bed leveling!?
Have you searched the net about it?
Let me try to explain again and forget this time the usual z endstop you have.
you want to start a new print and homing ONLY the X and the Y axis. Now the printer move the the endstops.
After that you have to start the auto bed leveling with G29.
Now the printer start to move to the locations you defined in the firmware, deploys the probe and measure the bed at each location( see the video I posted).
After that you get the measured values from the printer in pronterface or whatever software you use.
Then the printer start to print and use the measured values to compensate the print. You can see the z axis moving while printing.
The printer do not need a endstop longer, only the new probe. That's why you have to define the probe position in the firmware so the printer knows where the probe is and the nozzle.
I have the codes in my start gcode and everything do automatic.
My start gcode is(sorry don't have all gcodes right now because I write on my mobile):
-Set bed temp
-set extruder temp
-g28 x0 y0 homes only the x and y axis
-g29 do the probing
-wait for extruder final temperature
Hope you all understand now
