Hello all, I wanted to say thanks again for all your input and help bringing me up to speed!
I'm cranking away researching my Anilam 1100 retrofit, and I'm having troubles feeling secure about the parallel port as a robust enough device to control three or four axis of motion at modest 100ipm table speeds. I can see a PCI based I/O card doing it, but I'm feeling iffy about the parallel port. I know that EMC is super competent using either style device for it's main motion control I/O. The two axis Anilam 1100 machine I have now has a program/DRO resolution of 0.0001", and can machine up to 100ipm. I would like to retain these performance parameters after the retrofit at a minimum if possible. I think I read somewhere that EMC can control up to 8 axis (or more) of motion through the parallel port. What I'm concerned with is, how fast can it control motion compared to a PCI based I/O device. I read (I tried to anyway) a white paper on the specifications of the ISA parallel port standard. It really is not that fast of a device compared to the PCI bus standard. Well, it seemed that way to me. I'm looking to make this retrofit as reliable as possible, and get some decent performance out of it to. Is there a point in which the parallel port is not fast enough, or not a wide enough data pipe to do the job? Or is it fast enough for anything an automated machine tool would ever need? Parallel port? PCI I/O card as a port? Red pill? Blue pill? ;-) Sorry if this has been asked before: Are there any main stream commercial machine tool companies out there that use the PC's parallel port device for motion control? Companies like Haas, Mazak, Harding, Bridgeport, Hurco, Monarc, etc? Take care, David ------------------------------------------------------------------------------ Come build with us!
