Printer Model: CR-6se

Host / SBC:klipper host lattepanda delta

Hello i have been having a number of issues with my cr-6se and klipper. the current issue is after printing all day yesterday i started my printer up this morning to receive ‘Internal error on command:“G28”’ and the firmware restarts.

if i get klipper running, turn it of and leave it for a day it would not work when i boot it back up. I have at this point, remade my printer config file and reinstalled klipper itself. several times, each time it works well until i leave it for a while, This is quite frustrating as i am trying to like klipper.

There is a hint:

KeyError: 'homing_retract_dist'

it’s in here:

[stepper_z]
step_pin = PB4
dir_pin = !PB3
enable_pin = !PC3
rotation_distance = 8
microsteps = 16
endstop_pin = probe:z_virtual_endstop
position_min = -1.5
position_max = 250
homing_speed = 10
second_homing_speed = 10
homing_retract_dist = 10
  1. The second_homing_speed should be slower, usually the half of the homing _speed
  2. Is there a reason you increased the second_homing_distance? It usually is 5mm

Thank you for the quick reply @EddyMI3D! and for the added context for those parameters. it had been on 5mm prior and i had changed it to 10 in hopes of seeing a different result( not understanding it had to be 1/2 the value).
klippy.log (6.5 MB)
made the suggested changes and it is still is giving the same keyError unfortunately

WAIT, i just noticed in my printer.cfg my values list
[stepper_z]
homing_speed: 10
second_homing_speed: 5
homing_retract_dist: 5
but in the log homing is set to 5? how can this be?

In the log now it is this:

[stepper_z]
step_pin = PB4
dir_pin = !PB3
enable_pin = !PC3
rotation_distance = 8
microsteps = 16
endstop_pin = probe:z_virtual_endstop
position_min = -1.5
position_max = 250
homing_speed = 5
second_homing_speed = 5
homing_retract_dist = 10

After attempting to re-save the printer.cfg file with
homing_speed: 10
second_homing_speed: 5
homing_retract_dist: 5
the log shows that the config is not taking. i reinstalled klipper on another RPI 4 i had and it seems to be working now. must be something on the latte-panda not worth tracking down. Thank you @EddyMI3D !
