Hey legends,

I've accidentally deleted the contents of //CNC_MEM/MTB1 and //CNC_MEM/MTB2 on my Chinese VMC650 ( i believe its a Doosan copy?) with Fanuc Oi-MF control
Now every time I call up a tool change I get errors and alarms

Would anyone here possibly have the files required so i can put them back into the folder?
Attached are some images of the ATC and machine for reference.

I have searched the forum and found a few posts about similar issues but most are related to parameter settings or unknown causes of ATC functionality issues.

Thanks in advance.

So far ive managed to try some macro codes ive found on here.
Both of these result in the same thing
stored in MTB1 as O9001
Both move the Z to the correct tool change height for the arm to engage the tool
The drum moves to the correct tool number in the change position
then the code hangs and does nothing, the arm doesn't move, the pneumatic tool retainer doesn't disengage.

Below are the macros I've tried, any help would be greatly appreciated.

O9001 ;
#149 =#4003 ;
G00 G40 M9 ;
G91 G30 Z0 M19 ;
M06 ;
G#149 ;
M99 ;
%


O9001 ;
G80 ;
M9 ;
G91G30Z0M5 ;
G30X0Y0M15 ;
T#4320M6 ;
G53 ;
G90G0G43G54Z[24.99-[#[2000+#4120]+#[2200+#4120]]]H#4120 ;
G53 ;
M99 ;

look in the manual
maybe you have an M code for lowering the pot from magazine before reading the M6 command that will move the arm and change the tool and also an Mcode for put back the pot in magazine
Should be in the book as command:POT UP/ POT DOWN

Try this. It works on both my OM and 18M machines. Will likely work on yours too. Much of this is likely redundant, but it won't hurt anything or slow things down enough to notice.

Another idea... when you use the tool change programs that were listed in post #2 above, when it hangs, what do you see in the buffer area on your screen? Is it waiting for a FIN signal?

I got this sorted out, the OEM came through with the macro, ill post it here tomorrow in
case anyone else needs it in the future.

Thanks gents.

Can you share macros that were placed on your machine since I had the same problem? Please
