Hi friends, I solve the problem finally ...

I made the changes you told me and finished my homing and config files.
Unfortunately, even so and with a whole new wiring for the BLTOUCH...Not working yet...

Then I got an idea, but I wasn't sure it will work: I bought a new SD card, I copied the config files directly from "Original" SD. and WOOOOW all works magically at the first test!!!

How is it possible ???

Now I'm really happy!!
Thank you for yours suggestions which have been a great help to improve my knowledge and my configurations files.

Thanks so much to everyone!!!

@Sindarius said in Duet3 Mini + BLtouch - Z Homing problem:

@fcwilt

M558 P9 C"^io2.in" H5 F200 T6000                   ; set Z probe type to bltouch and the dive height + speeds

This line looks wrong I believe it should be

M558 P9 C"io2.in" H5 F200 T6000

Yes,but i have try this modify.Thanks

My connection is the same as that in your guide of Ender3.Tomorrow i try to do a new complete wires connection from board to Bltouch.

The config file and Homing file are the same of the first post i write.Now the only difference is the IO_3.

The problems are the same of the first post.

Thanks.

Thank you for your answers.
I have read the guides that you write me last evening,I had already set (IO_3) but as it doesn't work,I change on IO_2 for a test.

Today i have done other tests,check another time the wires,the connections and replace the BLTOUCH with a new one.

To have a comparison,I have check the config files that i use successfully on my Duet3 6HC and i don't undestand where the mistake could be

The problem is still there...

Thanks

Hi Friends,today I have started configuring my new Duet3 mini. But I have a problem when trying to home Z axis,Homeall and Bed Level.

The Homing with Sensorless X and Y axis works very well for me and i'm very happy,because i read that some other users have problems with this configurations...

The Bltouch it's original Antclabs, wires and connections on the board are ok.
I have upgrade the firmware first to version 3.2 (Final) and then to 3.3 (Beta) : there are the same problems.

The case it's this..
-M401,M402 and selftest work perfectly.

-If i move the hotend at the bed center and send (G92 X155 Y155) first and then (G30) the Bltouch works and records Z0.

-If I send Homeall,the X and Y axis go homing correctly,except the Z axis.
It goes in the bed center and start with its downward movement without however deploy the probe.

-If I send Home X firs and then Y separately and then Home Z,the hotend goes in the bed center, starts with its downward movement but the probe doesn't deploy.

This happen with all the other command that use the bltouch too... (G32 ecc) : The Hotend moves on X , Y and Z correctly but the probe doesn't deploy itself and will maybe crush on the bed.

I share the links my config files:
config.g
homez.g
homeall.g
homex.g
homey.g

They are not definitive configurations files,because I'm still working on it and perhaps I'm making mistakes.

Thanks for your help.

Hi Friends, i'm Leonardo and i have a question about the possibility to connect and check, on Duet3 Standalone mode, printer status with 3 or more Neopixel Rings.

At the moment i don't have a Raspi Board, but only Arduino nano and Arduino Uno R3.

I have the original sketch of BLV MGN Cube and i think that it is only to adapt at my configuration. It's true??

Thanks
