Describe your issue:

Hi everyone,

I am trying to get my CR10 V2 working using the example config config/printer-creality-cr10-v3-2020.cfg. I have uncommented the config details for the bltouch in the printer.cfg and run the initial flashing, Octopi installation on my RPI 3B+ and configuration steps as described in the guide. Besides the bltouch everything else is stock. My printer is creating weird results as it is not extruding as it should (the skirt line is printed with multiple layers), parts of the calibration cube test objects are missing. I am using CURA as a slicer, GCODE has been set to START_PRINT and END_PRINT.

Printer with Marlin FW 2.1.2 was working fine before. Any help or a working CR10 V2 printer.cfg would be awesome!

Hello @Ashen !

@Ashen

parts of the calibration cube test objects are missing.

That sounds like under extrusion. A picture of the printed model could tell more.

Have you already tuned the printer in?

You may check the rotation_distance of the extruder by

Extruder Calibration

or

Thanks, yes that might be the issue. I will test with an asjusted config.

@ EddyMI3D: I have tried a new config with a CR10 V2 rotation_distance setting. When running the BED_MESH_CALIBRATE, I run into this issue: Move out of range: -0.250 -0.650 6.000 [0.000]

I have tried a BED_MESH_CLEAR before and restarting the whole system, but keep getting this error. Can anyone help please?

Could solve it myself by incresing the bed_mesh values
to mesh_min: 47.50,1.75 so it was in bounds.

Thanks again and printing a calibration cube right now.
