To make threads is functional some times, but is not stable.
Sometimes we get Alarm no 185 (Feedrate overspeed).
Runnig about 20 items, then it suddenly do not work.


When we try to mill , example outer 6-edge , we get alarm 33 (Emergency stop), 204 (problem with control unit). Z4 overload, but we can drill holes with the c-axe.

If we tqake away YV16 (c-klamp) vi kan do outer milling , but can not drill with the c-axe.
