Chris, Your work is greatly appreciated. I use classic ladder on every machine. I tried the EMC integrated SFC programming and put it on the front burner to learn/use ASAP. I didn't work with it long enough to believe any problems were not my fault. Sorry for the lack of effort on my part. Ten years ago I used IsaGRAF with MDSI's OpenCNC. OpenCNC required the main program to be SFC and the other 4 languages to function inside the SFC program. I did not become expert at any of them. I used it to retrofit 3 Cinci 5 axis machines. I found it very flexible and powerful. The technical (and my personal) programing development ceased at the next upgrade. OpenCNC moved from QNX or Windows to run ONLY on Windows. I lost all interest in pursuing development in OpenCNC. I did (and still do) refuse to run my machines on Windows. One of the QNX/OpenCNC machines is still running. One broke and is sitting in a back corner disassembled. One of the QNX/OpenCNC projects is now running EMC2. I know - OpenCNC on Windows is a modified kernel running the Windows you interface with as an application. I thought my use of SFC/ladder was probably over when I started using EMC2. I am able to get what I need using C but the integration classicladder and now SFC is exciting. My C projects are not really recognizable as C but they seem to work for me. HEH :) :) I see so much nice and exciting work being done in the EMC2 world I wish I could clone (and educate) myself to be able to contribute to each and every project. Thank you very much for your work. Stuart
