Hi everyone,
in order to print a thin PVA support structure I wanted to change the BB-0.8 print core with a BB-0.4. My UM3E sent a warning, saying that "AA-0.8" print core is not compatible with PVA material.
I double checked that the print core that I had just inserted was actually a BB-0.4. I have cleaned the contact points on the PCB with a cotton swab and some alcohol, but my UM3E stills wrongly recognizes the BB-0.4 print core as a AA-0.8.
Do you have any suggestions to solve this problem? Thanks a lot in advance for your help.
