@Phaedrux i got everything wired up and the pin extend and retract but it does not light blue and it does not report a value. What could be wrong?
-
you will not see the bltouch value change, it triggers for a fraction of a second.
test it with g30 and triggering it by hand so you can power off if it does not stop.
-
@Veti i tried and the value on the webui will just show 0. I have tried while homing to and it will not report a value, so bed will continue even if the pin is triggered by me. Pretty sure it should light blue when active also.
I used these steps tio manually test also
"To test the setup with the nozzle maybe a 100mm up from the bed you can check if the trigger signal is reaching the Duet by attempting to extend the pin by using the following command:
M280 P0 S10
If all is well the web interface should report a value of ”0” or "N/A" in the Z probe column when the pin is extended. You can then lightly touch the extended probe pin to check that the value in the Z probe Column changes to “1000”
You can retract the pin again with
M280 P0 S90"
-
How exactly do you have it wired? And what does the M558 M950 commands look like in your config.g? Does it match what I showed above?
Are you wired to IO3 like this?
-
@Phaedrux it is just like in the picture, i made sure i have connection all the way to the probe using a multimeter so no broken wire.
i have not amde any changes to M950 or M558, It is just as the config did them.
M950 S0 C"io3.out" ; create servo pin 0 for BLTouch M558 P9 C"^io3.in" H350 F350 T4800 B1 ; set Z probe type to bltouch and the dive height + speeds + heater off while probing -
@Alucardi said in Duet 3 mini 5+ need help with wiring and config:
H350
Change that to H5. 350mm dive height is possibly problematic. But maybe not your problem here.
So just to recap. You're wired up to io_3 just like in the photo. Your config looks ok for io_3. And your deploy and retract macros look correct.
When you power on does the BLTouch do a self test?
Does sending M401 and M402 deploy and retract the pin?
Does sending G30 deploy the pin?
Does touching the pin after doing the G30 stop movement? -
When you power on does the BLTouch do a self test? Yes
Does sending M401 and M402 deploy and retract the pin? Yes
Does sending G30 deploy the pin? Yes it deploys during homing.
Does touching the pin after doing the G30 stop movement? It reacts to me pushing it but wont stop bed going up. -
Then I suspect a bad connection on the white wire to io_3.in. That's the trigger signal wire. Retest continuity. Recrimp it. Make sure it's in the shell properly. Make sure it's on the right pin.
As an additional check, please send M98 P"config.g" and report any errors. Also send M558 P9 and see if it reports back what you'd expect.
Also post your homeall.g

Gives me error

Homeall will be cleaned up and call for separate axels instead but i did it like this when i was trying to config sensorless homeing.

Ok how bout just M558

@Phaedrux M558

Try again after a reboot, and post your entire config.g please.

now it worked. M558 P9 still give same error though

Forget the M558 P9
Please fix the dive height M558 H5
Other than that it's down to the white trigger signal wire on io_3.in
-
@Phaedrux guess it decided to break it self then during me changing the card. I have continuity all the way to under the connector on the blTouch it self down to the end of the connector going into the card.
I will however before i order a new one make a short harness and try it on the bench. -
@Phaedrux it is working now. When i wired this up ages ago i connected ground further up so i only had to use one wire in the connector. I now reran one ground more. In the end i had 3 ground wires. that is why i had continuity on white.
Only reason i figured it out was cause i had the stick from the multimeter on the ground at the mother board and hit the white wire by mistake.
