Thank you for sharing your successful experience with the Centroid controller, it's a welcome plan B.
The tool changer controller is of particular interest in that conversion, as Marty asks, it is interesting to know whether you retained the Emco TC controller?
Thank you for your advice on the potentially degraded capacitor; you have given me motivation to take a look and inspect rather than conclude that all is lost and move on. I now appreciate that having the PC expansion RS422 card and (mostly) working software is a fortunate starting point (there was an error message hanging around, then the smoking board excitement).
The axis controller is made of 3 parts (large PCB, small biggy-back PCB and the top connections panel); it was the small PCB that looked like the source of the smoke, does this small board have a particular function?
Do you know whether there is a WinCAM licence within the software installation? I'm a bit concerned over the long term viability of the old Win98 PC and wonder whether I can install WinCAM on a newer PC? I've read messages on the subject of trying to create an image of the hard-drive so maybe this is a pointer to new installation not possible.
Many thanks for all info
