UM3 loading print-core BB says AA is in?

How do you fix the problem of the print-core BB being read as AA? This is annoying because I cant even load pva with the BB print-core in because it thinks AA is in.

That is annoying indeed. Your printcore might be wrongly programmed. Please contact your reseller.

As dorky as it sounds, try to clean the back connectors with Isopropyl alcohol. I like to use 99% pure to cut down on contaminants.

I switched a BB core out with an AA core and then back again and I must have touched those tiny, delicate contact points in the back and it would not make the adjustment. Cleaned it with the alcohol and it worked again.

I now make sure that I do not touch that area, but it is good to clean every now and then as air pollutants (Dust, moisture, etc) will eventually crud it up a bit.
