I have 18 AX12+ servos. I acquired them back in 2012 as part a Robotis Hunanoid kit. I subsequent reused the servos to build a hexapod. The servos worked as expected. After a year or so of tinkering, the hexapod was put aside where it rested till I tried to resurrect it this year while I was in isolation. But the servos, that were working back in 2012, I can not get working now. They cannot be “seen” by any controllers.
Working with just one servo to try and isolate the problem, I have it hooked up to a usb2Dynamixel and my laptop running the Dynamixel Wizard software. I have a 12V power supply hooked into the three pin Dynamiel connector to the servo and the common on the usb2Dynamixel.
With this setup, when I plug in the 12V power supply, the AX12+ led blinks once. When I use the Wizard to do a search for the servo it can not be found. When I try to do a firmware recover (after disconnecting and reconnecting the 12V power supply) once again the servo cannot be found.
Im using Dynamixel Wizard Version / 188.8.131.52
I am stuck. Any thoughts of what I can do next? or where I can get more help?
