Core XZ - Motors Configuration

[Kiwi3D]

HI Team....

Me again

Having issues with the CORE XZ - with the axis movements

If I go +X it goes right and down
If I go -X it goes left and up

If I go Z+ it goes up and left
If I go Z- it goes down and right

; Kinematics
M669 K2 ; configure CoreXZ kinematics

; Smart Drivers
M569 P0.1 S1 D2 ; driver 0.0 goes forwards (X axis)
M569 P0.2 S0 D2 ; driver 0.1 goes backwards (Y axis)
M569 P0.0 S1 D2 ; driver 0.2 goes forwards (Z axis)

Belts are what I would call medium, definitely not tight, or lose. I understand the impact of tight or bad paths for thee belts, having built a Voron 2.4

Appreciate assistance

Ray

@Kiwi3D can you modify the M669 line to this and try again?

M669 K2 X1:0:1 Y0:1:0 Z1:0:-1

Not sure if this is relevant. I removed the belts to check the motors are not causing the issue.

The left hand (X) motor rotates very little on both X and Z movements, but the right hand (Z) motor rotates considerably more

Is this relevant information?

@Kiwi3D your steps per mm for z should be the same as X I would expect
