I have seen that site before, google found it quite a while back. For what is almost a 1 off, figured I should be able to compensate the machine. I can make some teeny holddowns, but was afraid the small wood screws would gimp up the flatness of the jig about as bad as the pcb was warped. But its looking like that may be the preferred method for the next pass if there is one. I actually have one example that I think I can use right now, but it wasn't carved to even look like traces, just rectangular islands to isolate the connections needed, driving the mill by hand from the keyboard. Interconnections will be done in wire wrap, soldered. It is a 1 off, or possibly a 2 off if I get a bigger lathe & need another. Other than the opto's, the opto's led current limiting R's will be the only other parts it carries. By putting all 3 opto's on the same board, with the opto's held by 4-40 screws, it seems to me I can adjust the symmetry of the quadrature signals and the timing of the index by skidding the opto's around within the limits of the 4-40 mounting bolts, and do it considerably more precisely than having each opto on its own board and bracket, subject to being bumped during gear changes etc, at least until emc replaces the change gears. That is my eventual intention. Thanks Edward. To all the guys, it appears that 2.6.0-pre0 is running nicely on this new D525 based box. The single stick ram doesn't appear to be a problem. And a special thanks to Andy P. for the wiki page on isolcpus. It seems to have done the trick very nicely.
