bltouch v3.1 help😞

jobesynoob1234

well that was a waste of time soldered wires made no difference!
i also forgot about the error message after i used the G30 S-1 that says the (Z probe already triggered at start of probing move) its very confusing how all macros work and the only macro that seams to work different is the self test because they say it keeps going until you give it another command. But for me it stops its self after a bit $:\$

post a picture of all your wiring

That makes me wonder if the pin is dirty or damaged? Try taking it out by removing the set screw at the top of the probe body.

i seams fine:/

Phaedrux

Is the pin straight or a bent? Does it roll smoothly?

Does the mount of the BLTouch hold it perfectly straight up and down?

jobesynoob1234

the pin is fine i carefully placed it in my cordless drill the probe seams to lean to the left a bit

Phaedrux

I've noticed a similar lean on my own BLTouch probes. Maybe not that pronounced though. I'm not sure if that's a design feature or a defect.

Can you try adding a small spacer to remove the tilt? I suspect that the pin is getting caught on the edge.

@Phaedrux i believe that I may have put the tread inserts in a bit wonky i will try some springs and abs

jobesynoob1234

thats better got to love abs and acetone

Phaedrux

If it fits, it sits.

But does it fix the trigger issue?

jobesynoob1234

@Phaedrux i will give it a go but i think i better let that abs/acetone dry a bit more first just in case

jobesynoob1234

there must be something wrong in my settings. what i just did was homed the X then Y then set the probe with pin out then homed it it then keeps flashing once homed then every time I push home z it keeps moving up 10mm or so

jobesynoob1234

i also added this line to homeall and homez M280 P3 S10 I1 ; Alarm Release and Push-Pin down i altered it but i always end up manually having to deploy the pin

Phaedrux

I just had a look at your homing files from your first post. Are you still using those same files? They are set up to use a endstop switch, not the probe.

Compare your files to this: https://duet3d.dozuki.com/Wiki/ConfiguringRepRapFirmwareCartesianPrinter#Section_Homing_Z_using_a_Z_probe

@Phaedrux i dont have a g90 or g30 should i copy and paste

jobesynoob1234

in my homez that is

jobesynoob1234

just incase homez.g homeall.g config.g

Phaedrux

In config.g you have M280 P3 S10 I1 ; Alarm Release and Push-Pin down
But I don't think you want to deploy the pin at startup. I think S10 is just deploy, not alarm release. based on the Antclabs documentation: https://5020dafe-17d8-4c4c-bf3b-914a8fdd5140.filesusr.com/ugd/f5a1c8_d40d077cf5c24918bd25b6524f649f11.pdf

Instead, try adding this to the end which will clear any error state and retract the pin. You can also add that to the start of the homez and homeall

; BLTOUCH PREP
;
G4 S1 ; pause 1 second
M280 P3 S160 I1 ; Alarm Release and Push-Pin UP just in case it's in alarm and deployed
G4 S1 ; pause 1 second
M402	; Retract probe just in case it's still down

Your homeall will become this:

; homeall.g
; called to home all axes

G91                     ; relative positioning
G1 Z5 F6000 S2          ; lift Z relative to current position
G1 S1 X-290 Y-290 F1800 ; move quickly to X and Y axis endstops and stop there (first pass)
G1 X5 Y5 F6000          ; go back a few mm
G1 S1 X-290 Y-290 F360  ; move slowly to X and Y axis endstops once more (second pass)
G90                     ; absolute positioning
G1 X150 Y150 ; move probe to bed center. Change as needed.
G30 ; use the probe
G1 X0 Y0 ; return to home position

And the same basically for homez, since you need to move X and Y to position the probe, you need X and Y homed first. So homez becomes redundant. Just use homeall. You can use homez for some other specific homing situation later if you wish.
