I've came a what feels like a long way on my quest to learn to use my first real control and VMC, which happens to be a Fanuc 0M ("B" version I think). I have finally ran a full program via DNC upload and also drip feed.
Since most of my programs are larger than the 16k of memory this control will hold I have been trying to drip feed programs instead of going through the hassle of splitting the files up and sending them through in batches and deleting the program and uploading a new one and restarting it every 16k.
What I am finding is I get data starvation when I have short moves, like curved profiles. Part of the problem is I cannot transmit faster than 2400 baud. The manual shows settings up to 19200 baud (setting value "12"), which I put into the machine, but no matter what speed I select on the PC beyond 2400 it throws a 128 error/alarm when I start the drip feed.
I guess the first question is, does anyone have any ideas to work around that issue?
Secondly, does anyone have any ideas on cam software that uses more of the native g-code to create the arc/curves instead of interpolating lots of very short moves? My parts don't tend to have a bunch of super short moves, but it does tend to have arcs/circles in it and those are where I have to set the feedrate to a very low rate to keep the machine from being hurky-jerky.
I know the best option would be write the code from scratch, but these parts are too complicated for a mere mortal like me to create given the 3d features they often have.
