| By: Grall | Posted on: Aug 21 2009 at 11:13:21 PM | I have been using EasyDNC-trial with our "new" (1998) Shoda-router using a Fanuc 16M controller, just as described above. Everything seams to work great for transferring program back and forth to my laptop, using a RS232-cable with an RS232-USB adapter, again, just as described above. We also need to drip-feed some longer programs, but we are having trouble making this work.
With the controller in "DNC", we push cycle-start, and then "send" in EasyDNC, the program begins to feed, and the machine starts, changes tools, and begins to cut, but quickly gives a "buffer-overflow" alarm. We have enough memory in the machine to easily fit a program with 35,000 lines of code, but even with all of the memory available, I have only been able to get it to run 300lines of code before we get the "buffer overflow" alarm. Is the "buffer-size limited to a smaller-portion of the "memory-size", can I change this setting somewhere? I have tried reducing the baud-rate, as described, to the point that the machine "stutters", but still it does not seam to help us get further into the program.
I have played around with the flow-control setting, always matching the settings in EasyDNC, the port-setting in windows and in the Fanuc-controller, none of this seam to help, although sometimes the settings make the DNC-software wait indefinitely for the machine. I currently have the flow-control on everything set to the default X-on X-off, seams to be the best results so far. When the CNC buffer-overflows, sometimes EasyDNC continues to feed the program until I stop it. I have disabled the FIFO in the windows port-setting also as suggested.
I love this software for it's reliability, easy of use, and of course your asking price, but I need it to drip-feed, do you have any ideas? I only have 5-days left in my trial-period.
Any help would be greatly appreciated, thanks. | |
