BIQU microprobe issues

@Craigrobbo who said anything about M950 P5?
I think you need to look at the gcodes dictionary as you're confusing M950 and M558

Craigrobbo

@jay_s_uk Sorry You're right I was just adhoc typing while I was in bed (been a long day)

But yes the code I posted in my first reply is the code I am currently using,

Unfortunately, its just not working for me and its driving me mad - I am open to suggestions to try

jay_s_uk

@Craigrobbo ok, let's reset. Post the current code you are using.
Also, consider upgrading to 3.5.2

Hi, So As per advice I have upgraded to 3.5.2 - It hasn't fixed the issue but at lest I am now on the latest firmware.

The current code I am using is what I have posted in my very first post, I am open to trying any other suggestions you have.

Thank you for the help

While I have been having a play this evening, I tried your S280 commands again from your guide and this just causes very erratic behaviour, sometimes the probe deploys sometimes it doesn't then sometimes it randomly deploys and retracts on its own...

very strange.

@Craigrobbo your probe might pick up electrical noise.

@Craigrobbo as I've already said, your M950 command is wrong. You also don't use M280 but M42. Make sure you're reading the info for the microprobe and not the bltouch!

@Craigrobbo Make sure you're clicking on the 'BTT MicroProbe' tab on this page: https://teamgloomy.github.io/fly_e3_pro_v3_bltouch_3_5.html#micro
And make sure you know whether you have a V1 or V2 MicroProbe; I'm assuming it's a V2.

As @jay_s_uk pointed out, your configuration is wrong. You have:

; Z-Probe
M950 S0 C"duex.pwm5"
M558 P5 C"^!zprobe.in" H3 F250 T6000 A10 R1.25 S0.008 ; Set Z probe type/mode 9. H=Dive Height. F=Speed probe speed,

It should be

; Z-Probe
M950 P0 C"duex.pwm5" 
M558 P9 C"^!zprobe.in" H3 F250 T6000 A10 R1.25 S0.008  ; Set Z probe type/mode 9. H=Dive Height. F=Speed probe speed,

Also, add the G4 P500 pause to deployprobe.g and retractprobe.g:

;deployprobe.g
M42 P0 S1
G4 P500

;retractprobe.g
M42 P0 S0
G4 P500

Don't use M280 to deploy or retract the probe. If it still doesn't work, post pictures of your wiring at each end.

What should my M950 be?

*edit I replied to the wrong quote sorry!

@Craigrobbo that's got nothing to do with the configuration, but how your wires are run; i.e. if they run close to motor wires for a longer section. Best to try and get rid of that by either rerouting the wiring or by adding a ferrite bead.

I thought this but its too consistent when it happens.

I tried this thank you.

Unfortunately this also does weird things, So it homes, the probe comes out then it retracts on its own before the bed even touches it...

Now for an experiment I tried to touch the probe myself as to mimic a bed home and it just instantly deploys again, and again and will just indefinitely deploy every time i press it in without ever homing...HOWEVER if i let it just randomly retract on its own then it saves the home position... very very very strange.

As for wiring its currently tucked away but I am confident it is right.

I have it wired identical to my BLtouch (which works perfectly if i plug that in, so this confirms my wiring is right)

s for if its a V1 or 2 I m not sure but i bought it about 6 months ago?

I tried both P5 and P9 as mentioned I am going though different suggestions of code, P5 gives me less erratic results but P9 just sends the machine heywire doing random weird stuff and deploys and retracts on its own.

Its really strange, when in P5 mode the probe detects when its been touched, however in P9 mode it does not p9 makes it randomly deply, but P5 deploys once then never comes back for its second touch and then i get the error (probe already triggered at start of move)

With p9 it just never homes

I thought this too, was one of the first things I checked, i isolated the loom but this didnt help, also the results while random are repetable in terms of how it reacts to different commands and the timing of them

Sorry, i replied to the wrong quote, I meant to reply to the next one - I did seperate the wiring to mitigate it, also tried an actual BL touch and this works fine

oliof

@Craigrobbo are you saying BLTouch works after separating out the wiring, or Microprobe, or both?

The BLtouch worked when the cables re within the wiring loom and the same when seperated too.
