RRF3 Configure Z probe?

chas2706

Can anyone enlighten me how to configure DC42's ir Z probe in RRF3?
I have it physically connected to io3.in and in config.sys it is configured as:

M558 P1 C"io3.in" H5 F120 T6000 ; set Z probe type to unmodulated and the dive height + speeds

but it is not working or recognised.

Thanks in advance

please post your entire MsDos 6.2 including autoexec.bat.

I don't have an IR probe, so perhaps the settings for it are different. I do have a microswitch based probe on Z on a CoreXY printer, and it is configured like this:

M558 K0 P5 C"io3.in" H5 A5 T6000 S0.02   ; Z probe - Set the height of the bed when homing G28.  Combined with content of bed.g as invoked by G32, levels bed. Also used for Mesh. 
                                           ; P5 = Switch, NC
                                           ; C  = Input Connector
					   ; Hn = dive height
					   ;   A bigger dive height prevents a situation where the bed is out of alignment by more than the dive height
					   ;   on any corner, which can crash the hot-end into the bed while moving the head in XY.
					   ;   Probing speed and travel speed are similarly reduced in case the Z probe isn't connected properly (or
					   ;   disconnects later after moving to a point) giving the user more time to stop.
                                           ; An = Number of times to probe each point. 
                                           ; Tnnn = Travel speed between probe points. 
                                           ; Snnn = Tolerance when probing multiple times. Two readings inside this window and we move on.

And the home.z looks like this:

; Home Z Axis

G90 G1 X150 Y150 F10000 ; Move to the center of the bed
M558 F500 ; Set the probing speed
G30
M558 F50 ; Set a slower probing speed
G30
;G32                         ; Run 3-point bed calibration defined in bed.g

Hope that helps.

@Danal
Thanks for your rapid reply. It works like a charm now. I just made a silly mistake.
Again, many thanks.
