Duet 2 wifi RRF2.5 to RRF3 DC42 probe?



  • Hi all
    Had a DUET 2 wifi on my cartesian i3steel for a few years and its working fine
    Having read a bit here and there i'd like to try the latest RRF3 ( always trying to get the best out of my hardware) I understand the upgrade process version to version
    Where im struggling is how to implement my DC42 IR sensor

    My 2.05 config is

    ; Z-Probe
    M574 Z1 S2                                  ; Set endstops controlled by probe
    M558 P1 H3 F300 T3000                       ; Set Z probe type to modulated and the dive height + speeds
    G31 P500 X30 Y-10 Z0.55                     ; Set Z probe trigger value, offset and trigger height Bigger Z value = lower nozzle (55 rough/45 smooth)
    M557 X30:190 Y20:180 S40                    ; Define mesh grid
    

    The 3.0 config generated by the configurator is

    ; Z-Probe
    M558 P1 C"zprobe.in+zprobe.mod" H5 F120 T6000  ; set Z probe type to unmodulated and the dive height + speeds
    G31 P500 X30 Y-10 Z2.5                         ; set Z probe trigger value, offset and trigger height
    M557 X30:190 Y20:180 S40                       ; define mesh grid
    

    Im not at all comfortable with the new notation yet but the "set Z probe type to unmodulated " comment seems odd.
    Would appreciate some help
    Thanks in advance



  • @Phil-Maddox said in Duet 2 wifi RRF2.5 to RRF3 DC42 probe?:

    M558 P1 C"zprobe.in+zprobe.mod" H5 F120 T6000

    the probe only needs zprobe.in

    change to

    M558 P1 C"zprobe.in" H5 F120 T6000



  • @Phil-Maddox On my Deut 2 I have:
    ; Z-Probe
    M558 P8 C"^zprobe.in" H5 F120 T6000 ; set Z probe type to digital and the dive height + speeds

    That sets the IR sensor to digital mode.

    Plug into Z probe connector, signal to Z_Probe_IN. Power is from the connector, also.



  • Thank you both for the prompt reply and info. Much appreciatted
