      When I issue a g28 z the bltouch does not deploy and the nozzle hits the bed.

      My Z endstop exists and is attached to the board; however it doesn't indicate as triggered on the machine properties tab. (x and y do)

      Firmware Name: RepRapFirmware for Duet 2 WiFi/Ethernet
      Firmware Electronics: Duet WiFi 1.02 or later
      Firmware Version: 2.0(RTOS) (2018-06-05b3)
      WiFi Server Version: 1.21
      Web Interface Version: 1.21.1
      The printer is a Cartesian Makerfarm 'pegasus'. The bltouch is authentic.
      The commands:

      M280 P7 S160 I1; Alarm Release and Push-Pin UP
      M280 P7 S10 I1; Pin Down-- Send PWM channel 7 the s10 (angle) command
      M280 P7 S90 I1; pin up --Send PWM channel 7 the S90 (angle) command
      M280 P7 S120 I1; self test -- Send PWM channel 7 the S10 (angle) command

      work correctly.

      My config.g:
      0_1552929052793_config.g

          Here you go!

          I have the bltouch at ~8.3 mm from the glass to the shell. It is a bltouch smart.

            I suggest you update your firmware to 2.02.
            https://github.com/dc42/RepRapFirmware/releases/tag/2.02

            And remove M98 Pdeployprobe.g and M98 Pretractprobe.g from your homeall.g

            In config.g change G31 P500 to G31 P25

            And follow the directions here to test and calibrate the probe
