I just found out something interesting. I've implemented my own simple backlash compensation into my microscope Python test script that simply subtracts 0.08mm from the x coordinate when the head moves back and with this I was able to eliminate the x offset I always had on the center point. I now just see a very small movement in the y direction. Sadly the Duet firmware has no backlash compensation setting I could test.

@TheNetStriker said in BLTouch does not work anymore if M558 executed twice:

@fcwilt I've just tried that but that also doesn't work. The probe is just not doing anything after the second command.

As I suggested perhaps the firmware you are using works differently from what I was using when I was changing Z-probe type but I was able to change from one to another and back again.

The difference being I was not trying to change any of the parameters.

I would do this myself by I am out of town so Just as a test execute the M558 twice with the same parameters and see if that also causes the Z-probe to stop working.

On a second try the level was already better. I now reconfigured the z homing so it is probing against the z probe and not the end switch. Now the height map levels are quite good.
