thanks in advance

can someone help me with some tips on where to fix the problem ?

Maybe cleaning of control modules could help. Clean the rack connectors also.

I already cleaned the connectors on the boards of the rack and still does not start
battery is 3.7v is ok

Check power supply stability or try other ±24V PSU. Try re-installation of Okuma software.

I changed the CPU board (200US) it helped me.
The lathe worked more then half year.

Change the board. But if you can no do it change CNC to China. It will be more cheaper then buy board.

Thanks what do you mean Chang cnc to China?
Which board I have to change?
Please name the board.

I remove all OKUMA CNC with servo motors and drivers and install new China CNC TD1000 with 2 new servo motor and 2 new servo drive.
I have no any problem now.

hy aike :) this is the 2nd time i hear about someone replacing the cnc

here is the other : https://www.cnczone.com/forums/okuma...ml#post2076724

i think is a god idea ( especially if you can do it yourself ), to bring back to life an older model; thus if machine/mechanical is ok, then why not just rewire it ? kindly :)
