    @martin-s said in hell of a bed or I missed a config step:

    M558 P9 H15 F2400 T1200 ; Set Z probe type to bltouch and the dive height + speeds
    G31 P50 X-27 Y-10 Z0 ; Set Z probe trigger value, offset and trigger height

    You are probing way too fast for a BLTouch. Try F100 instead. You also don't have a Z trigger height set in your G31. That will need to be measured using: https://duet3d.dozuki.com/Wiki/Test_and_calibrate_the_Z_probe#Section_Calibrate_the_Z_probe_trigger_height

    It looks to me that you haven't run delta calibration, or if you did then you didn't save the results. See https://duet3d.dozuki.com/Wiki/Calibrating_a_delta_printer.
