Homing 2nd axis (sensorless) not working correct #198

Closed DerJOSh01 closed 1 year ago

DerJOSh01 commented 1 year ago

Hey there, i hope that I'm right to reach out in here.

I'm using the BTT Octopus 1.1 with BTT TMC2209 in UART with sensorless homing.

While NOT included klicky_probe my homing is working fine. Axis 1 moves to the frame, axis 2 moves to the frame. Each axis retracts a bit after contact. I attach the probe manually, home Z - everything ok.

I write axis 1 & 2 because the issue happens regardless which axis homes first.

If I include klicky it works like the following. Axis 1 moves to the frame, retracts a bit. Axis 2 moves a tiny bit in homing direction and retracts. Terminal sayes axis homed. This happens if I select home x/y only and if I select home all.

If I manually home axis 1 and after that axis 2 everything is working fine as well. After that i can home z properly - so the position of the dock is driven to correctly, it attaches, homes, docks and moves away. All like it should.

Before, I had an SKR Mini E3 V2 with physical Endstops and there everything works fine.

So could someone help me out with this?

Kind regards JOSh

what are your homing scripts. i believe you need to have a dwell time between homing X and Y, that's probably why it works manually

Hi, Thanks for the comment, but i need again a little push. I don't have any homing scripts except the original one, I think. The only thing I do is pressing the buttons in fluidd main screen. I don't know there or what the button leads to. Can you help me finding this or create a homing script?

Kind regards JOSh

check this guide https://docs.vorondesign.com/community/howto/clee/sensorless_xy_homing.html, should help. Klicky supports the _home_x and _home_y macros and uses them if they are found on the configuration.

Thanks, you got it. I followed the instructions and it mostly works. The thing I had to figure out is, that I for what ever reason, don't have to include homing_oderride. There my probe always showed as triggered so the klicky taught the probe is attached and homes instantly. So i went for commenting out the z option in homing_override but it didn't work. At last I don't include it and now it's working like it should! Thanks again and kind regards.
