Hello all.

The machine is a Doosan horizontal milling machine with an 18iMB control.

I've noticed sometimes while a subprogram is running from a memory card, all lines but the current and next block of the program are not displayed. The operator has also told me when this happens sometimes M0 doesn't halt the program and it continues to the next block. It doesn't seem like there has been an issue of blocks being skipped as this machine continues to make good parts, but most of the program is small movements in look ahead mode (G05, but it could be G08 -- I'll find out for sure here in a bit)

Does this sound like a data transfer rate problem? I have never seen DNC run in this shop since I've been here so I am not familiar with the symptoms of this type of problem, and this isn't the only machine that is running programs from a memory card here either, so I'm not coming up with good answers.

Edit. I was wrong about the look ahead mode. It is G08.
