I run a '96 KiaTurn 21 with a Yasnac LX3 control.
I just today got the AL55 alarm and the machine will not run.
The paper thin book that comes with the machine has a big blank spot next to the AL55 alarm.....
I sure would like to know something before tearing into it.
No manuals and no tech support for this machine at all.
If a solution is found I will post it.
Personally,If I bought a CNC It would require ALL service manuals to be included.
