Duet 3 RRF3 BLtouch
-
@baird1fa Duet 3 ? Or bltouch?
-
@mrenz999 both. I’ve got a BLTouch and a duet 3. Sorry the interference I think was between the duet 3 and the BLTouch.
-
I don't suppose you have an oscilloscope?
-
@Phaedrux Sorry. I do not

@Phaedrux
The z probe is showing triggered on the machine tab, and it's value is 1000 on the dashboard.
Does it matter that I am using io3 ? Should I change it to 7 ? -
It might matter. The documentation says to use io4,5or7. I’m using io4 and it works.
-
@baird1fa That's what I was thinking. Going to just swap it to 7 and see what happens. Will update either way.
-
@baird1fa Ok changing it to 7 had this effect. Homed x and y fine. No change. Moved to center of bed and before it headed towards the bed it probed the retracted the probe and stopped moving with an error that the z probe was already triggered. So it triggered at the beginning of the start of the bed movement. Bed is still far away from the probe.

I rechecked all wires. Unplugged and replugged it in. Hard cycled the power and now it seems to be working. Thank you everyone for your assitance
-
I’m glad we were able to help and you are up and running.
-
it bet that internally that pin4,5,and7 are the only ones able to do a servo signal.
it would be helpful if there was some error handling built into the firmware that would throw an error when you try to configure an incorrect pin to do servo commands.

I only checked that io3.in was able to analoge in, my bad!
