made the changes you suggested, and it is getting it to a working state. there still seem to be a noticeable delay that changes from probe to probe. but none of them are long enough to error out the BLtouch.
so its working, but not sure if it behaving as intended. but maybe as good as it gonna get on a pretty unusual config.
Yup

@dc42
tried updating, and after that i also tried reinstalling duetpi-lite.
both have not changed my problem
so i have tried two things today.
first i tried running with the probe set as P8 and this seems to work just fin.
video
then i tried to switch out my current BlTouch 3.1 to an older 2.2 running as a P9.
this BlTouch does not have the same issue as the 3.1 but instead does a double bounce on retraction.
video
with both it does not seem to error out the Bltouch, but the 3.1 still seems to experience the hang up when deploying and retracting.
@dc42 Tried it, it did not change anything.
but i think the problem lies in deployment and retraction of the probe
because if io do a repeatability test with the following code it does not hang anywhere. as it does not deploy and retract the probe between touch off.

M402
is there maybe a way to get it to not retract and deploy the probe between each point in a G29, as a quick fix solution?
any instructions on doing number 1. as i at the moment i dont have a resistor handy?
edit:
is it this
@phaedrux
so tried removing my PT100 sensor and paneldue from my config to see if that was making somekind of problem.
it did not help.
busy grasping at straws here 
@nmsmith89
interresting, i was thinking it was something more to do with it being duet 2 and sbc
@phaedrux
my dive hight and speed was normally what you sugested but changed it trying to diagnose the problem.
but i have changed it back now to test
also changed the G31

it homed z fine, ran G29 2 times and both times it failed within the first 5 probes
Edit: just had it happen on a z-axis home

so i made a quick video that shows, a z home, x-axis level, and a G29 that shows they way it hangs at times
it also ends failing the G29
https://www.youtube.com/watch?v=p5xrNgZ7IoQ
the error the paneldue show, i have not seen before as i so far have only seen DWC in a browser that shows, ""probe already triggered before probing move started""
Hey
i have recently upgraded to Duet 2 wifi running in SBC mode (Raspberry Pi 3b, duetPi lite). and I'm slowly wokring my way through a few issues but atm i am having quite a lot of problems with my BlTouch.
it deploys and retracts with M401 and M402 and also worked perfectly before with out any problems .
but after the upgrade the printer hangs when it has to deploy and it hangs when it triggers before then retracting the probe, and sometimes during probing it will then fail and give a "probe already triggered before probing move started"
it seems to happen mostly when running a G29, but also sometimes happens with a G30, that i use to level the x axis, how not observed it when homing z.

no errors when i do a M98 P"config.g", after duing the changes @jay_s_uk suggested and the z axis is working great now.
iam how ever chasing my tail with some problems with my Bltouch
it deploys and retracts perfect with m401 and m402, also have not had any problems when homing the Z axis.
but when it does a G29. the printer hangs when it has to deploy and it hangs when it triggers before then retracting the probe, and sometimes during the G29 it will then fail and give a "probe already triggered before probing move started"
Thanks that fixed it, wonder why it was never a problem before
So i was working on it a bit more, and it seems i get this error when i try to home the z axis
Error: M350: Driver 2 does not support x0 microstepping with interpolation
Driver 4 does not support x0 microstepping with interpolation
and it seem to report that even if i change the microstep value
i am in the progress of setting up my printer to run with a Duet2 wifi +Duex5 in SBC mode, and i have got it connected and Working.
i do how ever have a problem with my z axis steppers not moving.
i have tried to send a "M564 S0 H0" and then move the axis, also did not work.
the 2 z axis stepper are connected to drive 2 and 4, and the jumpers are in place at drive 2
my config.g is just the same one i used before upgrading to SBC mode.

all the other axis homes and moves just fine.
when i try to home the z axis, the printer will do noting for some time, while i trys to move the z-axis up a bit, then it will move the X and Y to the center of the bed and deploy the Bltouch, and just stay there.

i updated from 3.1.1 to 3.2.2 earlier today and encountered a problem with the way i use a filament sensor i then tried going to 3.3B2 to see if the problem was the same and it is.
i only use my filament sensor as a check when i switch filament with a MMU2 and as such require it to be disabled in the M591 command
so my command is M591 D0 P1 C"xstop" S0
and in version 3.1.1 when checking with sensors.filamentMonitors[0].filamentPresent
it worked just fine.
but in 3.2.2 and 3.3B2 where the object model har changed to
sensors.filamentMonitors[0].status
it will only show the status as "ok" as long as the filament sensor is disabled in M591
to get sensors.filamentMonitors[0].status working i have to enable the monitor in M591 and that will give me problems during printing as a retraction will sometimes trigger it.
picture show my console where the status command only shows as "noFilament" when i enable the monitor in M591
even when a "M591 D0" command show it as no filament present
So i have messed with it a bit more trying to use some while loops.
pretty much this
while !sensors.filamentMonitors[0].filamentPresent
G1 V1 E1 F1000
and that actually works okay up to a point. the loading it smooth and continues. but the problem seems to be that it might be buffering some moves because it will continue moving a bit after triggering the filament monitor.
i then tried adding a G4 P100 or a M400
this makes it so that it triggers at the correct time but makes it run slow and chopping as it moves 1 mm stops, moves 1 mm, stops and so on.
@Phaedrux said in Stopping 2 axis with 1 endstop:
@lahn92 said in Stopping 2 axis with 1 endstop:
It can be done with stall detection to load filament.
https://duet3d.dozuki.com/Wiki/Stall_detection_and_sensorless_homing#Section_Using_extruder_stall_detection_during_filament_loading
Yeah that's the way i already have it working it's drives the filament untill it stalls on the extruder gears. And they drives the v and e axis 10 mm. And the uses the filament monitor to check for correct load.
But my problem is that the conditions change quite a lot making the stall detection hard to tune.
