Buzzer conected to out3

Tinchus

yes. I have done this:
M950 P0 C"out3" ; assign gpio port 0 to out3 for buzzer. control win M42 P0 SX range 0 to 1
M42 P0 S0 ; turnoff buzzer

@jay_s_uk I have included these lines at the end of my config.
When I tun on the printer, the buzzer starts beeping, seems like the M42 is not being read. If I send manually later
M42 P0 S0 ; turnoff buzzer
it turns off.
Im trying to see what Im doing wrong

jay_s_uk

you shouldn't need to use M42 in your config.g file.
Can you try removing that line so only the M950 is present?
Does the buzzer start to make a noise on reboot then?

Tinchus

@jay_s_uk
I removed the M42 and only the M950 line is left in the config. The buzzer starts to make a quick noise just when the machine reboots, so that is why I added th M42, trying to shutit down.

jay_s_uk

that will be a blip before the config loads, although I don't know why its doing that.
Is this a duet 3?

Tinchus

@jay_s_uk yes, I though it could be possible to hear something at the very start up, but the buzzer doesnt stop.
Weird is that is not accepting the M42 command in the config for stopping it.

Silly question, but what happens if you just apply 12\24 volts directly to the buzzer ? does it make a continuous buzz\sound or just 'blips' on the connection ?

If the former, then you aren't getting an output on the Out3 pin, or maybe not enough current? if the latter, then you would probably need to define a frequency for the 'buzz\beep'.

e.g. for case lights I use fan2 (see relevant part of config.sys) but as its also for lights I've wired up an additional regulator to supply the required current for the LED strips

; Case Lights - Uses Fan 2
M950 F2 C"fan2" Q500 ; Create fan 2 for case lights and set frequency
M106 P2 F100 S0.01 B0.00 C"Case Lights" ; Set Case LED's (Fan 2) to minimum

Tinchus

@Dr_Ju_Ju If I apply 24V directly to the buzzer, it sounds continuosly without stopping.
out3 have more than enough current because it is a connection than can be used for a heater, the buzzer only needs 0.1 amps I think.
If I delete the lines from the config and manually send:
M950 P0 C"out3"
and then M42 P0 S1, the buzzer starts to sound without stoping, a values of S less than 1, changes the frequency of the buzzer, and a value of 0 stops it.
The problem arises when setting the 950 from the config file.
When the printer start, the buzzer makes a non continued bli: bip bip bip bip,
So you think I need to define a frequency on the M950? Setting a frequency of 0 makes the buzzer beep at a very low frequency at start, setting a value of 65000 makes the buzzer sound at a really fast frequency at the start.

Tinchus

Well, I solved it , somehow, dont know why/how exactly:

I changed the definition of the pin number from 0 to 5:
M950 P5 C"out3"

and now when printer starts, the buzzer is in silent...

@Tinchus said in Buzzer conected to out3:

M950 P5

Do you happen to be using M950 S0 for a BLtouch or something?

dc42

Please post your complete config.g file.

Tinchus

@Phaedrux No, I have a capacitive sensor, but it is not defined in conflict, I checked (I think)

Tinchus
