I have been using DC42's Mini Differential IR height sensing board successfully for a while but yesterday I did some maintenance on my printer and the probe no longer works correctly.
I get the 4 flashes on startup but the sensor readout on the Duet 2 board stays at 456 for the z probe readout, the LED lights when I put a surface close to the probe but the readout stays the same. Any ideas"
M558 P1 X0 Z0 F120 T6000 ; Set Z probe type to modulated, the axes for which it is used and the probe + travel speeds
G31 P500 X11.0 Y5 Z0.6
