I have been reading the Klipper docs and currently, I am trying to attain a theory on why my T8 leadscrew is not moving the Z-axis gantry.

I used to have a "T7" or 7 mm rod that my gantry was handled by at the time...

  1. Since the "upgrade," I have noticed that my gantry does not move.
  2. I have a cartesian style printer w/ T8 leadscrew for the gantry/Z-axis movement.
  3. Since the upgrade, I have also noticed a slight hum that has been resolved w/ rotation_distance from the klipper docs.
  4. I erased my config, had to start over, and have a new OS.
  5. The motors for X and Y move just fine, i.e. exactly like they are supposed to move.
[probe]
pin: ar100:PH4
x_offset: 0.0
y_offset: 0.0
z_offset: 1.1
speed: 3
lift_speed: 6

[stepper_z]
step_pin: ar100:PL6
dir_pin: ar100:PE10
endstop_pin: probe:z_virtual_endstop
rotation_distance: 8
microsteps: 16
position_min: 0
position_max: 152.0
homing_speed: 8.0

In the above snippet, this is part of my main config reference, I have a [probe] and this [probe] has speed and lift_speed which require specific options.

My notes are gone. I cannot calculate lift speed any longer due to lack of instruction and I am thinking, from what I can remember, speed is traversing the XY plane.

The Klipper documentation and configurations were not at fault as I figured.

I went through the documentation, set up instances of different configuration options, and readjusted printer.cfg options.

Anyway, it turns out the lead screw was faulty and bent. Calculating Klipper configurations will NOT prove useful with a bent lead screw.

Also, because of the rotation of the lead screw per one turn, I had to adjust the rotation_distance in the printer.cfg file.

Also...rotation_distance for XY, Z, and E all need separate-real values that are configured and this set of examples can be found in many places online like w/ the Klipper docs, https://all3dp.com/, and the reprap wiki.
