Printcore 0.25 not recognised in UM3x


Recommended Posts

Posted · Printcore 0.25 not recognised in UM3x

I've finally used the official 0.25 Ultimaker printcore that I bought about 2yrs ago but never had the occasion to use before.

My printer is an Ultimaker 3 Extended, last stable firmware. Last Cura 4.6.1.

 

Problem: changing the printcore 1 from the standard AA0.4 to the new AA0.25 my printer always thinks to have attached an AA0.4.

I did try changing it two times, I cleaned with alcool the printcore contacts (but the 0.25 core was brand new and enclosed in a plastic bag). Nothing. Always recognised as an AA0.4.

I did calibrate the XY axis after changing the core: all did work.

I did override from Cura the not recognised 0.25 and it did print perfectly, no problems (great core for details).

 

Nonetheless I'd like to solve this problem, otherwise I must override the raised error for every print.

Any idea? Many thanks in advance

    Hi,

    there are a few printcores that have been programmed wrong. AFAIK, @gr5 knows a procedure to correct this.

    I hope, he recognizes this post and can help. I know it's simple, but i don' find the post anymore.

    Regards

    MATERIAL/PRINTCORE

    scroll down to

    PRINTCORE 1 but don't click it.  Look at the bottom of the display.  Repeat for PRINTCORE 2

     

    If one of your cores is programmed wrong (for example it's an AA 0.4 but the printer thinks it's an AA 0.8) then you can fix it by using the instructions here:
