Voron trident Z stepper moves differently

[Azertime]

Hi, I am building A self-sourced voron trident (400x400x500 build), with a BTT Octopus PRO v1.1.

Everything is going great for now, toolhead is doing what it's supposed to etc.
Only I am now configuring the 3 Z-Steppers and they are doing completely different things.

1. front left is noisy and when buzzed only moves down
2. Rear functions exactly as expected
3. front right doesn't move at all

I followed the wiring guide correctly, and used the provided config file and I can't find a solution for this particular problem (I use TMC2209 drivers)

Here is Z-stepper config sample I currently have :

##  (+) value = endstop above Z0, (-) value = endstop below

I tried different things, the motor front right motor which doesn't move is still humming slightly. I wonder if it has something to do with the motors winding.

The first thing I'd check is the motor wiring. Then I'd check the pin assignments. Here's mine for my Octopus 1.1

Thank you for your reply, I'll check that and have a look at your config, also I initially didn't mention this but I am going for a klicky probe on my setup. Don't know If this has an influence for my problem or not but I guess not.

 

[claudermilk]

No, Klicky shouldn't be a factor at this point--you're just trying to get them motors moving correctly.

 

[Azertime]

fixed, it was my wiring some crimps had snapped

thank you anyway for your help, I am starting to test homing now XY is ok but for Z it prints "Move out of range: 207.000 405.000 10.000 [0.000]"

do you have any clue ?

 

[claudermilk]

Check your X and Y min and max. Is that 405 move actually within the defined range? Where is it trying to move to home Z in the safe_z_home section?
As an example, here's mine for my 250 Trident:

[safe_z_home]
#  XY Location of the Z Endstop Switch
#home_xy_position: 142,260
# Changed to middle of bed for Tap
home_xy_position: 125,125
speed:100
z_hop:10

Note that the original location for the spec switch was just off the back of the bed. For Tap it's the center.

 

[Azertime]

Thanx a lot ! I managed to get It working, Homed all axis and done a Z-tilt, But I am stuck again ...
I tried following the Klicky-Probe Guide and installed all macros and stuff, added my z endstop pin location, and also the dock location, but now It won't home any saying "Macro G28 called recursively"

As my knowledge of klipper macros is somewhat limited, I can't figure out where it gets looped.

Edit : After some research it has something to do with knomi macros renaming G28 to G28.1
