Is there any advantage to using a bus connected Mesa card like the 6i25 vs using one of the Ethernet-connected cards such as 7i92M or 7i93
It seems that Ethernet would allow me to control the CNC Mill and lathe from any computer even the ones in the office and also from a computer that lacks a PCIe bus slot such as a Raspberry Pi or notebook PC But I ask because possibly there is some reason to stay with the bus-connected cards. That said, I am getting good enough performance from the parallel port. "Good enough" defined as the motors and mechanical parts being the bottleneck. But I want to install an encoder on the spindle and also experiment with 5 uM glass slide encoders on the machine. So I just might end up with 5 high-speed quadrature encoders (Spindel, x,y,z,a) and that is simply NOT going to work over a parallel port. BTW my "cheapest possible setup" Mini Mill is coming along. I am in fact noting some flex in the plastic parts and have some ideas for an improved design. I think it is normal that designs "mature". The Z and X-axis are solid but my dial indicator tells me I can do better on Y. It seems that a complete CNC conversion can be done for under $500 with little to no machine work required -- Chris Albertson Redondo Beach, California _______________________________________________ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
