CR10S5 SKR 1.4 Turbo Y not homing

General Discussion
1

Basic Information:

Printer Model: VZBot 330
MCU / Printerboard:SKR 1.4 Turbo

having issues when homing the y-axis on CR10-S5 with SKR 1.4 Turbo.

in the printer.cfg i have Y setup as below

[stepper_y]
step_pin: !P0.19
dir_pin: P0.20
enable_pin: !P2.8
microsteps: 16
rotation_distance: 40
endstop_pin: !P1.28
position_endstop: 0
position_max: 500
homing_speed: 50

When I go to home, the motor doesnt want to move, makes an awful noise, and I hit the emergency stop.

I run M119 and it shows y endstop is not triggered. X works just fine for homing.

Any thoughts?

Hello @Noble8 !

You deleted some lines in the template. No good.

A code snippet does not help here.

Please attach the klippy.log to your next post as a file. Please no file servers.

Thank you!

Check the motor wiring.

also

[stepper_y]
step_pin = !P0.19     # <-- Remove the !
dir_pin = P0.20
enable_pin = !P2.8
microsteps = 16
rotation_distance = 40
endstop_pin = !P1.28
position_endstop = 0
position_max = 500
homing_speed = 50

Same for [stepper_z]

Sorry I had forgotten about those as I was playing with it trying to get it to work.

Removed and y will still not home.

Means?

No movement at all, wrong direction or something else?

7

No movement at all.

Loud buzzing like it wants to move but stuck.

I checked that the bed moves smoothly without power, checked the stepper cable, checked resistance on each line making sure it wasn’t a-b anywhere.

Stumped.

Homing X works just fine

You may swap the stepper driver to check if there is a fault. (e.g. Y ↔ E)

Also check Vref of the driver.

9

swapped the motor to x and confirmed it works.

Vref of the y driver was 1.2 measured from the multimeter

10

It was meant to check the stepper.

11

swapped that as well, it works

12

finally figured this out, stepper motor pinout was different than the board. Swapped the pins and is working fine now.
