7815 The machine is not initialized.
Then there is a problem with the Z axis, the Z axis can not be referenced. Our actions: try to change the hard disk with another earlier saved working copy. This does not help, the Z axis still can not be referenced.
Then we try to throw off the signal cable of the Z axis encoder, turn on the machine without the encoder. Then turn off the machine, reconnect the Z axis encoder and turn on the machine. After these manipulations, the Z axis begins to be referenced.
What's happening? The problem with the encoder or maybe it's in some kind of battery. The MC 422C has a buffer battery, maybe it's in it?
