Now… BlTouch, hope the penultimate...
-
There is some formatting of testing Bltouch….
I think if Bltouch work with macros... This part, these 3 wires are OK...
The problem must reside in z probe wiring....
Only ocurrs put an obstacle in probe before reach the bed.. For avoid crash...
Or some m command what test Bltouch the same manner there is a must command what test Endstops...
Don't know..
-
One idea…
This is posible to realice...
If macros work.. This means that strip with 3 wires, are Ok... Red, brown and orange.
Of the other strip, 2 wires, black and white.
.Black is GND, no signal... But white is Z PROBE.
I have few knowlement of electronic. But when probé is triggered, Bltouch emits current for the Z PROBE pin?
And this current will be 3.3v or 5 V if I have not cut the back track.I can meassure, with a multimeter, this current? Between Z PROBE(white) and GND(black). No? This signal will can be read when probe is pushed. No?
Thinking in high..
TEST MAKED
BlTouch works properly...
I have used a multimeter.... and conect to White and Black...
I have select Continuos Tension, 6 V range.
With macros:- When BlTouch is deployed, in multimeter can read 0 V
- When, BlTouch is retracted, in multimeter can read 3.14 V
Of this... can conclude:
*BlTouch works
*BlTouch rear track, for transformation of 5 V to 3 V, is correct cuted
*grsgdsgwgdw.... me cago en to..- I see two posibilities:
A- I haven't connect BlTouch (Black and white) in correct place
B- I havent a correct config, attach for review, please.
; BL-Touch
M307 H3 A-1 C-1 D-1 ; reserve pin 21 for M42 or servo use

;INCREASE VALUE WILL LOWER NOZZLE CLOSER TO THE BED, DECREASE THIS VALUE WILL RAISE THE NOZZLE FROM THE BED -
Hi,
In config override there is:
; Z probe parameters
G31 T1 P25 X0.0 Y0.0 Z1.20
G31 T3 P500 X0.0 Y0.0 Z0.70
G31 T4 P500 X0.0 Y0.0 Z0.00Erase and calibrate?
This… not work, another head crash

mmmmm…...
i think, i am close....
Well, searching in this forum, i have find this:
Sure feel free to use the video. I should have tidied up my workbench! I haven't seen any documentation related to using a BLTouch with RepRapFirmware, but it's pretty straight forward to get going…
BLTouch 5V leads are connected to expansion header pins 1-2, and the servo lead is connected to pin 21 (PWM for heater 3)
BLTouch endstop leads are paralleled with a 240ohm resistor as documented by Antclabs to make it safe for 3.3v logic and connected to E0 endstop header
M307 H3 A-1 C-1 D-1 is added to config.g to reserve pin 21 for M42 or servo use
M558 is set to probe type 4 and G31 is set for a very low trigger value since the BLTouch only triggers the endstop for 5ms
Deployprobe.g macro contains the line M280 P3 S10 I1 to deploy the BLTouch probe
Retractprobe.g macro contains the line M280 P3 S90 I1 to retract the BLTouch probe
Deploy and Retract macro]s are added to bed.g and homing macros
And I think that's about it...I think with this i have corrected a mistake… i connect White wire, in [E0 STOP/X STOP] and no…. seems, i have to connect to [E0
STOP/3.3v].Why i think this.... because when i have conected in [E0 STOP/3.3v], in web interface, in MACHINE CONTROL/SENSORS, now i can read this:
Sensors-Vin –>24.6V ;power of psu
Sensors-Zprobe -->1000 ;this means Bltouch is deployed
Sensors-Fan RPM -->0 ; normal... i have no fanbut....i think i am close, but dont work
-
I have read,with a multimeter,the voltage at the entrance of duet Wi-Fi, and I HAVE read 3,1v. It's enough for activate Z probe? Nominal tension there isn't 3,3v….
-
Hi,
I have not tested…. But the info in this url, seems very good...
Dc42, please, can you confirm what that info is correct?

I don't have a bltouch, but from what I know about it, that info looks ok to me. Most users without a DueX2 or DueX5 expansion board use Heater 3 for the servo instead of Heater 7.
-
i don't know to do…
i have made a thousand probes.... and none works.
1- HARDWARE: I think that (brown, red and orange wires(In Heater3)) are ok... Why? Because macros of retract, deploy and test BlTouch work.
2- HARDWARE:I am pretty sure the track is well cutted. BlTouch go in 3.3V. I have checked continuity with a multimeter
3- HARDWARE:Black wire, is not connected
4- HARDWARE:White, is connected to Z-Probe Socket, in Z_Probe_in PIN
5- SOFTWARE: I have included in config those:
M307 H3 A-1 C-1 D-1 ; reserve pin 21 for M42 or servo use
M558 P5 X0 Y0 Z1 H3 F200 T5000
G31 P25 X0 Y0 Z1.13 ; Set Z probe trigger value, offset and trigger heightSomeone call tell me if missing something?
Only one strage behavoir,,, Today, yesterday i can, when a multimeter measure voltage betewn White (3.3V) and Black(GnD) i can read 0,02, aprox, if BlTouch is deployed or retracted. Yesterday i can measure 3.1VAdd:
With this config.... when i can read 1000 in start screen, painted with a type o grey.... and when try to calibrate, touch the probe by hand, and retract, and deploy....but not stops nozzle... and when run macros, probe deploy or retract, but Z-Probe in start screen, not chages, rest in 1000, with a shaded background
I don't know to do.... Please need your assistance. I have forget something?

Black wire should be connected to the GND pin on the Z probe connector, as described in the wiki.
When the probe is deployed but not triggered, the Z probe reading should be zero, or close to zero,
-
HI…..
One posibility....
If BlTouch is Version 1... No version 2.
- Is posible that not work with i wait i i have cutted the track?
whats the solution...
- Solder cuted zone. ¿It will work?
-And put 480Ω (ohm) resistor betwen Black and White wires? - How i can know what version BlTouch i have?
- If i have cute the track, and apply tension.... BlTouch will be ok? or maybe is broken?

Its the same…. too i have try
