DC42 IR Probe analogic mode on Duet3?

[ernstc]

My previous board was a Duet2 Wifi and there the IR probe was configured to work in analogic mode. Infact at startup it used to flash 4 times.

With Duet3 board the documentation says that the DC42 IR probe must be configured with mode 8, that is digital. Now at startup the probe flashes 2 times indicating the digital mode.

Why it does not work anymore in digital mode on Duet3? Or am I missing something?

Duet 3 has permanent pullup resistors on the endstop inputs to make them compatible with endstop switches and BLTouch. That's why the IR sensor starts up in digital mode.
