Hello,
I have tried to make the auto bed leveling feature work.
At first it worked fine with a manually installed z-probe.
I have now put the probe on a servo controlled arm.
When i now use the auto level feature it does not work properly anymore.
The main issue is that the printer height is not updated, it keeps the printer height from the eeprom, wich is a bit higher than the real printer hight to allow adjustment.
The second behaviour i did not notice in my previous configuration is that after the third measurement, the probe travels back to the starting point and at the same time lowers to z=0, that is z=0 according to eeprom printer height wich is too low ! so it cruches in to the bed.
Than the x axis moves the value of the probe x-offset, and this now becomes x=0 !
At last the z axis goes all the way up to measure the printer height, again does not update printer height.
I also tried to do the procedure without homing the axis before. So all values show red. I put G28 in the start script to see what happend.
In this case, the homing takes place, but all the values stay red.
It's like everything that happens within the G32 S2 command, is not accually written to the firmware.
Any suggestions ? I tried really hard to understand but i'm stuck, Sorry.
