    An illustration of the location of the IR sensor and the LED would be useful.

    I can run through all the calibrations without error but when the R2 starts any print, the extruder buries itself directly into the print bed and errors out. I cleaned the IR sensor and the light comes on when paper is raised up just below it.

    After sending the M119 command I get this: 

    Recv: Reporting endstop status
    Recv: x_min: TRIGGERED
    Recv: y_max: TRIGGERED
    Recv: z_min: open
    Recv: z_max: TRIGGERED

    Any ideas? Bad IR sensor?
