BB print core coded as AA by mistake?

Recommended Posts

I inserted a new BB print core in my machine in slot 2 this afternoon, and when I attempted to load a reel of PVA, it said that the material is not compatible with an AA core...??

 

I unloaded and re-loaded the core, and the same with the material.  The core is clearly marked BB 0.4 on the black plastic but the machine seems to think it is an AA.  What should I do?

... Also, the hexagonal portion of the nozzle is marked with the letters BB.  Not that it would have anything to do with the coding, but this proves beyond reasonable doubt that the core itself is indeed BB and must be a software/firmware coding error.

I'm glad you mention this as I was going to ask you about that before you program it.  Well UM would say to return it to your reseller but you can easily reprogram it.

 

First put your UM3 into developer mode - it's in the menus on the UM3.  Your machine needs to be on your network (wifi or ethernet) if it isn't already.  Once it's on the network it will show the IP address at the top of the main screen.

Next you need ssh which is built into linux and Macintosh terminal but not windows.  For windows I recommend putty:
https://www.chiark.greenend.org.uk/~sgtatham/putty/latest.html

In putty you don't type the "ssh" part but just put the ultimaker@111.222.333.444 part and click "open".

ssh ultimaker@1.2.3.4  (don't enter 1.2.3.4 - enter the ip address listed on your UM3)
username/password:   
ultimaker/ultimaker   (much easier than root/ultimaker as it takes you straight into the utility to do sendgcode)

Choose the type and size from the list below - T0 is left slot and T1 is right slot so before running any of these make sure the core you want to program is in the left slot if it will be AA and in the right slot if it will be BB

After programming the core, slide it out and back into the slot at which point the UM3 will re-read the eeprom and realize it's new state.  The software that does X,Y,Z offset calibrations for a core goes by serial number and that can't be changed so you won't lose any calibration data when you do the below changes.
