But can find one under m5i20 which is what I'm using. So I think I'm still stuck about how to pet/feed the dog.
Show all *dog* does reveal an m5i20.0.watchdog-reset which is set to FALSE. I've been unable to set it TRUE so don't know what to do next. Just as an aside: When I fire up axis and home and then try jogging the velocity shows while I have the mouse down and then goes to zero when I let up. However there is no attempt to drive the servo motor.
