Corrupt XY offset file


Recommended Posts

Posted · Corrupt XY offset file

I was wondering if anyone had come across an issue with the XY offset file becoming corrupt. Updating the firmware doesn't fix things, It'll always print this strange pattern. That's actually only half the pattern, I'll continue with the X rectangle at the top but tries to draw it too far back past the limit and starts grinding the gears a little. It always prints models fine, there's just no way for me to set the offset.

 

Ultimaker 3 with firmware version 5.2.16.20200331 (most up-to-date at the time of writing)

    There is a problem with the right print core, notice how this pattern isn't printed. I suspect the calibration data for the nozzle switching bay got lost or corrupted.

     

    Could you try the tests under menu: Maintenance / Diagnostics / Switching test

    When this shows problems, then calibrate the Switching Bay position under the menu: Maintenance / Calibration / Calibrate lift switch

    Thanks for the help CarloK. That first image wasn't the full calibration print. I didn't want to let it finish as the print head tries to print too far back and starts to grind against the back of the printer. See below for the full print with both nozzles. As you can see it's very random compared to what should be printed. I did the switching test and all seems fine with that. It prints files perfectly fine, just doesn't want to print a normal XY offset.

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

    This type of problem in the XY calibration print most likely comes from using a print core with a bad configuration (there is a small programmable memory on the print core).

     

    See this thread for how to re-program the printcore. Note that there are different files for Ultimaker print cores and 3dsolex cores.

    Looking at it again, the 3dsolex 'solution' will not fix this specific error. Leave a note here when you have 3dsolex so I can look into it.
