@Phaedrux hi!
thanks for the replay!
Yes the internal fuse burned, i don't know why!
All the other part of the printer stay up!

Is not a risk put this fuse inside?

Hi to all,
i'm Angelo and i'm devoloping a printer with 6 M23CL 3 for Z, 2 for Y and 1 for X.
I first powered the engines individually to correctly configure the addresses and then connected them all to the duet3d tool distribution.

They worked properly for about 30 minutes, after that all six engines stopped showing no flashing or steady LEDs and now even after a new poweup they do not give signs of life and the connection can time out. What could have happened?

No fuse on the distribution board is broken
Board 6HC v1.02
Motor M23CL no Brake v1
Tool Board Distribution 0.5v

DSF 3.5.2
DWC 3.5.2
RRF 3.5.2

Power supply 24V 10A
