Configurazione bl touch antclabs

perfetto

Buonaseara, ho montato bltouch sulla mia scheda duet 2 ethernet . firmware version 2.03 , web interface version 1.22.6 la spiegazione letta mi mi dice di utizzare canale heater3 pin 8 sul configuratore rrf version 3.4 mi fa decidere dal menù a tendina E3 ma non funzyina.
ricaricando il file jonson lo ritrovo impostato a E2.
Gentilmente potreste aiutarmi come risolvere.
Grazie

Good evening, I mounted bltouch on my duet 2 ethernet card. firmware version 2.03, web interface version 1.22.6 the explanation read tells me to use channel heater3 pin 8 on the rrf configurator version 3.4 it makes me decide from the drop-down menu E3 but it doesn't work.
reloading the jonson file I find it set to E2.
Please could you help me how to solve it.
Thanks

You should use E2 (extruder 2). Heater numbers are from H0, which is 'bed heater'. So E0 = H1, E1 = H2, and E2 = H3, and you want to use H3 'heater 3' pin.

It's possible that the json file does not save the probe pin, and you will need to set it each time you go back to the RRF config tool. This won't be fixed, as we are no longer maintaining the old RRF config tool.

Consider updating RRF to the current version, see https://docs.duet3d.com/User_manual/RepRapFirmware/Updating_firmware#updating-from-older-firmware-versions

BUONASERA GRAZIE PER L'AIUTO, HO INSTALLATO FIRMWARE VERSIONE 3.3 ANCORA PEGGI NON FUNZIONANO NEMMENO I RISCALDATORI PROVERO' LA VERSIONE 3.5.4 , TENGO A PRECISARE CHE DAL 2020 LA STAMPANTE ANDAVA BENE, ANCHE NON ESSENDO UN VETERANO HO DECISO DI MONTARCI IL BLTOUCH.
QUANDO CONFIGURO RRF IL FINECORSA DELLA Y FACCIO BENE A DISABILITARLO O PUO' ANCHE RESTARE COME SICUREZZA, ANCHE CON LA NUAVA VERSIONE FIRMWARE IL PIN 8 DELLA PORTA DI ESPANZIONE HEATER E NON FUNZIONA ,SE CONFIGURO SULLA PORTA HOT AND E1= AD E2 IL FILO LO DEVO COLLEGARE SU E1 PWM V_IN ?
EVENTUALMENTE E' CONSIGLIABILE PASSARE AL FIRMWARE 3.6 SU DUET2 ETERNET.
grazie tanto per l'aiuto

Good evening thanks for the help, I installed firmware version 3.3 even worse the heaters do not work I will try version 3.5.4, I would like to point out that since 2020 the printer was working fine, even not being a veteran I decided to mount the bltouch on it.

Please post your config.g, and the response to M122. When you update to RRF 3.x, you have to update the config.g, as RRF 3 is different from RRF 2. You can downgrade back to RRF 2 if you find it too difficult. See https://docs.duet3d.com/User_manual/RepRapFirmware/Migration_RRF2_to_RRF3

Ideally, update to the latest release 3.5.4, then use the configuration tool to make a new configuration set of files. Then we'll help you fix the issues.

When I configure RRF the limit switch of the Y am I right to disable it or can it also remain as a safety device,

Endstops are only used during homing moves, so most of the time they are disabled anyway. You can set them up as 'triggers', so that they pause the machine if they are touched. See https://docs.duet3d.com/User_manual/Reference/Gcodes#m581-configure-external-trigger

even with the new firmware version the pin 8 of the heater expansion port and it does not work, if I configure on the hot port and e1 = to e2 do I have to connect the wire to e1 pwm v_in?

Are you following the guide here? https://docs.duet3d.com/en/User_manual/Connecting_hardware/Z_probe_BLTouch
See also the BLTouch troubleshooting guide here: https://docs.duet3d.com/en/User_manual/Troubleshooting/BLTouch_troubleshooting
Again, seeing your config.g would help. Make sure your deployprobe.g and retractprobe.g are correct, too.

Possibly it is advisable to switch to firmware 3.6 on Duet 2 Ethernet.

Yes, Duet 2 Ethernet will be supported by firmware 3.6, but it is still in beta at the moment. It should be releasing soon, though. Your config from 3.5.4 should work with 3.6 without changes.

@droftarts Buonasera, ho caricato il firmware 2.05.1 se voglio agganciare il filo giallo del bl touch ei =a e2 del configuatore rf devo utilizza il pin pwm v_ in o al pin +3.3 V.
grazie

Good evening, I loaded the firmware 2.05.1 if I want to hook the yellow wire of the bl touch ei =a e2 of the rf configurator I have to use the pwm v_ in pin or the +3.3 V pin.

The yellow wire is the control wire for the BLTouch. It should connect to a PWM pin, usually heater 3.

E2 in the configuration tool is heater 3. This is referred to as M307 H3 in the firmware and config.g and M280 P3 in deployprobe.g and retractprobe.g.

Your wiring should be:

Duet Z Probe connector pin	Duet expansion connector pin	BLTouch pin	Colour
IN		Out	White
GND		GND	Black
	5V (pin 1)	+5V	Red
	Heater3 (pin 8 )	Control	Orange or Yellow
	GND (pin 2)	GND	Brown or Blue

Your configuration should be
in config.g

; Z-Probe
M307 H3 A-1 C-1 D-1                     ; disable heater on PWM channel for BLTouch
M558 P9 H5 F120 T6000                   ; set Z probe type to bltouch and the dive height + speeds
G31 P500 X0 Y0 Z2.5                     ; set Z probe trigger value, offset and trigger height

in deployprobe.g

M280 P3 S10 I1

In retractprobe.g file

M280 P3 S90 I1

If you are still having problems, post a picture of your wiring at the BLTouch end, and at the Duet end.

@perfetto it is possible the wiring colours are different, or reversed. See https://docs.duet3d.com/en/User_manual/Connecting_hardware/Z_probe_BLTouch#pinout-and-wire-colours
