We bought a early 2000s mill about a year ago with a Siemens 840D controller and had some problems getting it up and running. One of the repair guys who came in removed the network card and the guys who managed to get the machine running couldn't get it re installed. So they set us up loading programs using the serial port and a DNC program.
All of our jobs are one offs and almost all are 3d so the files tend to be big. The transfers take a long time but our machining cycle times are long as well. It took 80 minutes to load the toolpath than is running right now that has been running for the last 5 hours and probably has another hour or 2 to go. The long load times would not be that big a deal if I could load the next program while the machine is running. Would this be safe to do? We run the jobs from the controller hard drive as they are too big to "load" we would be uploading and downloading to the same hard drive.
We are transferring at a baud rate of 57600. The technician set it up faster for us but the first large file we tried uploading, it cut off the end of the program.
