Z axis problem


Printer Model
Voron 2.4
Extruder Type
Clockwork 2
hopefully you can help me because I'm lost. The Z offsets sent to the motors are not correct (see below) when running a QGL.

Making the following Z adjustments:
stepper_z = 6.572249
stepper_z1 = -5.637549
stepper_z2 = -6.653091
stepper_z3 = 5.718391
9:08 PM
Average: 10.051036
9:08 PM
Actuator Positions:
z: 3.478787 z1: 15.688585 z2: 16.704127 z3: 4.332645
9:08 PM
Gantry-relative probe points:
0: 13.265000 1: 5.712500 2: 6.242500 3: 13.855000

As you can see steppers z1 and z2 move negatively correctly, but z0 and z3 move in a positive direction. And to top it off z0 is double the offset any ideas? attached is my config file
. I'm running an MP8 with Steathburner and CAN bus.

thanks, any input would be welcome.

ok scratch that after taking more stock of the situation. The calculations are ok, its my stepper movements (physical) that don't correspond to the calculations. i have Z0=stepper 3 Z1= stepper 4, Z1 = stepper 5 and Z3= stepper 7. I must admit I'm perplexed will try again tomorrow.

Ok for any newbie's like myself out there just building a Voron2 with Klipper (coming from the Duet world) Here was my answer after many searches' trials and tribulations. All the following was my fault however I could easily see it done by other builders.
a) Reference X0 and Y0 have to be front LHS same as motor Z0
b) When doing a QGL follow the direction of the motors i.e. probe motor0 then motor1 motor2 then motor3.

and after 4 nights of frustration, it lives and does a QGL correctly.
Anyway, just thought I would add my findings and solution.
