bltouch and g28 head crash

[ckigar]

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
