New BB print core shows up as AA

Recommended Posts


I received a new BB print core for our UM3 extended. While I have been waiting for this print core I have had the extra AA print core installed in the second print head slot. Now when I change heads the machine still think it's an AA core installed, complaining about incompability with materials etc.

The print core is brand new and the connectors look clean. I updated to the latest firmware while I was waiting for my new BB print core.

It's possible to program it if you are good with ssh. If you are comfortable with ssh send me an email at gr _at_ gr5.org and I'll send you instructions.

Also look at the nozzle itself very carefully. It should have a tiny AA or BB on the nozzle.

Or you can just send it back to the reseller where you bought it.

    • Taking Advantage of DfAM
      This is a statement that’s often made about AM/3DP. I'll focus on the way DfAM can take advantage of some of the unique capabilities that AM and 3DP have to offer. I personally think that the use of AM/3DP for light-weighting is one of it’s most exciting possibilities and one that could play a key part in the sustainability of design and manufacturing in the future.
