slow dive or fast dive F200/F800

  • hi guys,
    which kind of dive yields more accuracy and consistency with the Bltouch.
    The same question would also apply to the NPN inductive sensor, I currently got the the 5v 2mm sensor.

    Please Help.

    For the BLTouch the slower the better. I use a faster probe first to save time in case the bed is far from the nozzle, and then a final probe at F100 for greater accuracy.

    M558 A1 F350			; Set single probing at faster feed rate
    G30 				; Do a single probe to home our Z axis
    M558 A10 F100			; Set tripple probing at slower feed rate
    G30				; Probe again to get a more accurate position

    I can't say for other probes, but I think that would generally hold true. A piezo probe may have a minimum speed to register cleanly though.
