UM3 y axis calibration / the printer is almost printing outside the bed

[Niles 0]

Hi

My UM3 Extended is almost printing outside the bed ( y axis )

How can I fix this?

What type of print core are you using? Is it an original Ultimaker print core?

When the print core is not an official Ultimaker core, then I suspect the print core was programmed with wrong data.

 

I don't see the second print core printing material. Why? I'd like to see that for reference as well.

I just found your other thread where you report print core problems.

My conclusion is that there is a problem in reading the configuration data from your AA 0.4 print core.

 

You can re-program your print core by:

- Disable Active Leveling (not required, but saves 5 minutes).

- place the core to be programmed in the slot on the left.

- print one of the files below.

- Remove the print core. When you insert it again the new configuration will be read.

 

Note that on this forum there are alternative methods for programming the print cores, but these have the following problems:

-  Only the print core  names are changed. Other parameters that should be there are ignored which create problems in XY calibration like you posted above.

- The checksums are not updated. When a new firmware will check this for errors, then the printcores will be rejected.
