If I have to do that, I might as well go back to the eagle files & square
one. I tried to lay out a series of holes along the end of the board for
for the cable termination but didn't drill the holes quite large enough,
making it difficult to get all the 22 gauge wire in the star-quad cabling
into the holes for soldering, nor was the via pattern I used large enough
to allow the correct sized holes, then throw in that the other end of the
board has a superglued strip on it with 3 teeny little pots to trim the led
brightness in the interrupters which reduces the noise in the encoders
output quite a bit, and I should just go back to square one by ordering
another bag of the opto's. A good winters project. And one I have been
considering before.
The cable itself where its soldered into the board has been inspected with
a very strong glass, no stray strands, no nicked insulation can be found,
but I don't feel good about the appearance either. And next time the
boards hold down bolt area WILL be isolated from the machines frame too.
That initially caused a miss-count or 3k. But a better ground fixed that
right up.
However, this doesn't answer the question about anyone else having written
a "peck cycle" using the G33.1 routine and had it work perfectly, or if
they too had encountered a duck that walks & quacks like this one.
Thanks Gregg.
Cheers, Gene
