Posted · Anet A2 after Cura 4.8 just spitting filament

Loaded Cura 4.8 after 18 hours of 19 hour print diving print nozzle deep into print.

Uninstalled 4.8 reinstalled 4.5 now no matter what I try and print.

Nozzle goes to lower left corner and spews filament in the corner?!

Help!

Anet A2 v:2.0

    As you have probably guessed, it's likely a printer issue.

    Query the printer using the LCD and write down the Home Offsets, steps/mm for all axes, and anything else you may have customized (like z-offset if you have an ABL system).  If you are running a flavor of Marlin you can send M502 to the printer and do a factory reset.  That will put the firmware back to the "as delivered" state.

    Start a text editor (like Notepad) on your computer.  The file will only be four lines:

     

    M502

    M206 X?? Y?? Z?? ;This is for the home offsets.  Enter the numbers you recorded

    M92 X?? Y?? Z?? E?? ;This is the steps/mm.  Enter the numbers you recorded.

    M500

     

    Save the file as "reset.gcode" and put it on your SD card and "print" the file.  The firmware will be reset, the Home Offset and steps/mm will be changed to what you had, and M500 saves the changes.  Then try printing a calibration cube or Benchy and see how it goes.  If it is still a mess, then I suppose next would be to consider that something is amiss on the mainboard.
