dear sir

MO2 AND M30 BOTH STANDS FOR PROGRAM END
IN ANY MACHINE ONLY ON IS APPLICABLE
SO BEFORE PROGRAMMING PROGRAMMER MUST CONFORM THAT WHICH M CODE HE SHOULD USE FOR PROGRAM END

Fine correction : M02 = reset the program only; whereas M30 = reset as well as rewind to the start of the program. There is clear cut difference between the two.

Good catch guys. I will make the change to the original list so it reads correctly.

Thanks for the help,
Ivan

Good Morning sir ,
can you please tell me what is M58 .
regards

Hi
M Codes is different for different makes of CNC machines, G Codes are more standard. M19 on Tongtai Topper is spindle brake on. M11 on Efamatic is conveyor off, and so is M06 and M07 chuck open and close, and some more. By the looks of this, Machine Builders use M Codes to their like, not to a standard. This is sometimes very confusing if working with different Machine Makes.

Hi there.
On our machine (Doosan puma 400 LM) M58 is to close the steady and M59 is to open the steady.A bit late I know but maybe it will help

I dont think its necessary to correct Ivan as those seem to be the basic M codes and YES they do vary from manufacturers, Perhaps its best to first find out the machine type and or controls before trying to help identifying the code.

I found the best way to identify all the M codes on any machine was to try each one in the MDI or MDA mode, it really helps to know your machine better and also discover its capabilities.
