CNC communication: RS232 vs. flash drive

The Fadal tech taking care of NJ, PA, and a bit of NY was surprised when I axed about RS232, his response was, Why go for 10 year old technology, when flash drives work so well, AND, he sez, can DNC!!! At least the one from CalMotion.com does. http://www.calmotion.com/products.html Not sure which product is which, but I'll find out when I call. Supposedly they make a portable version (wireless?? not sure), so that I can use one for both the Fadal and Haas, when it comes in. Any opinions on the "obsolete-ness" of RS232 vs flash drives? Previous threads on this indicated to me that RS232 was the better way to go, so mebbe y'all can remind me why this is -- esp in light of the tech's claim that these calmotion flash drive units (which replace the 3.5" floppy) dnc as well . This tech sez lots of his customers have the calmotion unit, and luvit luvit. Which, btw, he does not sell, so there would appear to be no bias, vested interest. I have RS232 communication with my Fadal and the other CNC machines in my shop. Cons: I have to switch between cables with a selector switch, I had to run cables to each machine. Pros: the cable was cheap. I can make up new cables easily and cheaply for new machines. The cable is cheap. Did I mention that the cable was cheap? Oh, and I can drip feed the machines through the cables if needed, but I have never needed to. Eric |

CNC communication: RS232 vs. flash drive

It's simple, reliable and inexpensive. Even a CADACAM monkey can plug in the cable without help, and most know enough to leave them alone so the boss doesn't have to call you out to fix it. Do any of them use USB to RS-232 converters? |

You fix your badly leaking roofs yet, Terrell or are you still trying to get someone to do it for free because you can't? |
