In regard to my previous post:
I did an extra test & disconnected the blue wire (signal In / Out)
With only Vcc & GND connected the mini IR Probe LED blinks 4 times.
My conclusion from this test is that the board does not correctly initialise the Probe.
Is this a correct conclusion?
Could this be because of the enstop configuration ("M574")?
I have a Duet Maestro mainboard with the latest firmware: 3.0RC1 (2019-12-16b8)
Ref: https://duet3d.dozuki.com/Wiki/Gcode#Section_M574_Set_endstop_configuration
M574 - RepRapFirmware 3 Parameters
Xnnn Position of X endstop: 0 = none, 1 = low end, 2 = high end.
Ynnn Position of Y endstop: 0 = none, 1 = low end, 2 = high end.
Znnn Position of Z endstop: 0 = none, 1 = low end, 2 = high end.
P"pin_name" Defines the pin name(s) that the endstop(s) for the specified axis are connected to. Needed when S=1.
Snnn 1 = switch-type (eg microswitch) endstop input, 2 = Z probe (when used to home an axis other than Z), 3 = single motor load detection, 4 = multiple motor load detection (see Notes).
==> What to do if you want to use a Z probe for the Z-Axis
Example:
M574 Z1 S1 P"zstop" ; Z min active high endstop switch
==> no need to refer to the pin_name for the Z Probe_In?
I would greatly appreciate if someone could help me with initialising the mini IR Probe in the config.g file for the Maestro board (firmware 3.0RC1)
