  1. I tried the gcode and the print core has been correctly renamed. In the beginning the UM3E wouln't print the gcode from the USB. I just turned the printer off and on again with the USB still inserted and then it worked. Thanks a lot to you all for your help!
  2. Hi gr5, thank you very much for your help. The engraving in the nozzle is the same as on the print core. I have checked your reprograming files and I have a question: you say that the the files will rename the the core in the left slot. How can I rename the core in the right slot?
  3. 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.
