Powered on my machine and had this error on the interface. I followed the on screen instructions but was not able to overcome the issue. Interface Firmware version 1.51 any help is greatly appreciated. I have a 1515 with blackbox interface and xyz probe.
1) Make sure you followed all the steps in docs.openbuilds.com/interface chronologically 2) Also test your BlackBox against a PC - if it also fails to connect its possible your BlackBox is damaged (in which case, go over your wiring and find any shorts)
