Describe your issue:

Dear,
I bought my printer just four weeks ago, so I would for sure call me a noob in these things. I have searched the board for these things, but couldn’t really find a solution. So - if I oversaw something, please guide me.

My issue is that my 0,0 is not where it should be, but the y axis is roughly 10 mm “to high” - so the home position should rather be 0,-10. I just realized this after trying to have a full plate print where the printer head got in conflict with the base for the nozzle cleaner.
Just to be on the safe side here - after I read here, on reddit and wherever else, I understood that I need to update my printer.cfg within the “stepper_y”-section.

Currently it looks like this

[stepper_y]
step_pin: PB8
dir_pin: !PB7
enable_pin: !PC3
microsteps: 32
rotation_distance: 40
endstop_pin: tmc2209_stepper_y:virtual_endstop
position_endstop: -0.5
position_min: -0.5
position_max: 227
homing_speed: 30
homing_retract_dist:0

Did I understand it right that it needs to be updated to

[stepper_y]
step_pin: PB8
dir_pin: !PB7
enable_pin: !PC3
microsteps: 32
rotation_distance: 40
endstop_pin: tmc2209_stepper_y:virtual_endstop
position_endstop: -10.5
position_min: -10.5
position_max: 227
homing_speed: 30
homing_retract_dist:0

If so, will that as well be reflected by the slicers (in my case Orca)?
And how would I need to (or do I need it at all?) change the “bed_mesh” section, currently like this

[bed_mesh]
speed: 150
mesh_min: 5,5
mesh_max: 215,215
probe_count: 6,6
fade_start: 5.0
fade_end: 50.0

Thank you for bumping my head into the right direction.
Regards
Gilhin

  • This printer comes with a modified and non-standard Klipper. Likely only Creality knows what they have done.
  • It should work out of the box as it is set up by Creality.

Before you start messing with it and potentially making things worse, you should check if there is a different root cause and consult Creality.

That’s a pity - however, I will try to find some answers on the Creality side.
However - thank you for your effort!
