I am now working on setting up easyDNC to communicate with the controller. When we dump an entire job over to the controller, we have no issues. The job is copied over entirely and the machine runs with no issues. These jobs are smaller in size, so they fit on the built-in memory.
When we attempt to drip feed a larger program, we start running into issues. First off, it would stop at 180 lines and alarm out with a buffer overflow. This turned out to be that the serial settings were wrong. We were able to straighten out the settings, but now the job stops at around 360 lines and alarms out with a buffer overflow. I attempted to increase the Block Delay, and this did help a little (getting to the 360 line point), but even increasing it to the maximum setting resulted in a buffer overflow.
DNC settings:
Baud: 9600
Data bits: 8 bits
Parity: Even
Stop bits: 2
Flow Control: Xon/Xoff
