I was running a mold roughing program via drip feed this afternoon, and the very long program finished sending, however the mill stopped feeding in the middle of the program. I've never run a program this long before, but I imagine the issue is with the buffer in the machine (VMC w/Mitsubishi Meldas 64s control), but IDK maybe I've got baud rate too high? I think I have it at 19200. It's definitely transmitting faster than the mill can machine.

At 9600 it runs really jerky, so I sped it up. Was that a mistake?

Have you had this problem before? How did you fit it?
 
Sounds like you got one of those 'union computers' and it must have been about nap time.
 
What DNC software are you using? I use DNC4U with my Meldas control and there is a check box on DNC4U that says something like "Keep port alive after sending". That box must be checked. I think what happens is if the PC RS-232 port turns off after the data is done being sent, the CNC treats that as some kind of stop despite data still being in the receive buffer that has not been processed yet.
